Ron Ananian shares insights from his remote broadcast in Pennsylvania, discussing the importance of finding a capable mechanic rather than just a good or honest one. He recounts a humorous encounter at a radio repair shop that leads to a deeper conversation about customer expectations in auto repair. The episode features listener calls, addressing various automotive issues, including a Nissan Kicks' mass air flow sensor problem and a Toyota Sequoia's four-wheel drive engagement issue, providing practical advice and troubleshooting tips.
Remote from “somewhere in Pennsylvania,” Ron turns a repair-shop counter chat into a bigger question: don’t shop for the cheapest or the flashiest—shop for the capable. Then the phones fly: a 2021 Nissan Kicks with a stubborn P0101 (use calculated load & fuel trims, don’t parts-swap), a 2024 Highlander maintenance roadmap (fluids early and often), a 1970 Impala idle-stop solenoid lesson, a 2002 Sequoia stuck in 4WD low (likely front-diff actuator/binding—stop driving, inspect), and a 2002 Cummins with dead batteries (charge correctly, then parasitic-draw test <50 mA).

OBD2 stands for On-Board Diagnostics II, a standardized system that allows external devices to communicate with a vehicle's computer. It provides diagnostic information about the vehicle's performance and can help identify issues.
"I want you to see what, what fuel trim is number one. All right. And, and where's fuel trim? Short term, short term, short term, long term."
Fuel trim is how your car's computer changes the amount of fuel it uses based on how well the engine is running. Short-term fuel trim is for quick changes, while long-term fuel trim is for changes over time.
Fuel trim refers to the adjustments made by the engine control unit (ECU) to the fuel mixture based on sensor readings. Short-term fuel trim adjusts the mixture in real-time, while long-term fuel trim reflects adjustments over a longer period.
"But calculated load is our, is our key denominator there. If this is a 2 liter engine at idle, we're going to see roughly 1.8 to 2.5 grams of air flow per second or calculated load."
Calculated load is a way to measure how hard your engine is working. It helps mechanics figure out if something is wrong with the engine's performance.
Calculated load refers to the engine's current workload based on various factors, including air intake and engine speed. It helps diagnose engine performance issues.
"Hey, Ron, I own a 2024 Toyota Highlander. What recommendations would you make for fluid changes?"

The Toyota Highlander is a midsize SUV known for its spacious interior and family-friendly features. The 2024 model continues to offer a blend of comfort, technology, and performance, making it a popular choice among families.
"The engine is a 2.5 liter with a supercharger. I believe Toyota's recommendations are too long if I want to keep the car from more than 10 years."
A supercharger is a part that helps the engine get more air, which makes it more powerful. It helps the car go faster by giving it extra power when needed.
A supercharger is a device that forces more air into the engine's combustion chamber, allowing it to burn more fuel and produce more power. This results in improved performance compared to naturally aspirated engines.
"And especially a supercharger, turbocharger, I think is what you're trying to say."
A turbocharger is a device that uses the engine's exhaust to help pull in more air, which allows the engine to burn more fuel and produce more power. It's a way to make an engine more powerful without making it bigger.
A turbocharger is a type of forced induction system that uses exhaust gases to spin a turbine, which compresses incoming air into the engine. This process increases the engine's efficiency and power output without significantly increasing its size.
"A big fan of oil changes every 5,000 miles. I think it's an absolute must."
An oil change is when you replace the old oil in a car's engine with new oil. This is important because it keeps the engine running well and helps it last longer.
Oil changes are routine maintenance tasks that involve draining old engine oil and replacing it with fresh oil. This helps to keep the engine lubricated and running smoothly, preventing wear and tear.
"Trans fluid at 50. Trans fluid between 50 and 60."
Transmission fluid is a special oil that helps the car's transmission work properly. It keeps everything running smoothly and helps the car change gears.
Transmission fluid is a specialized lubricant used in vehicles to keep the transmission system functioning properly. It helps to cool and clean the transmission while also providing hydraulic pressure for shifting gears.
"The front transfer case, if we want to call it that, or the power takeoff unit on that particular car, has less than a quart of fluid in it. And you can't imagine the abuse that it's taking in terms of heat and power distribution."
The front transfer case is a part of some cars that helps send power to the front wheels. It's important for keeping the car stable and moving well, especially in tough driving situations.
The front transfer case is a component in all-wheel drive or four-wheel drive vehicles that distributes power from the engine to the front wheels. It helps manage the vehicle's traction and stability, especially in challenging driving conditions.
"I think fuel system cleaning at 30. Where you're going to hook up the physical machine and clean the rail."
Fuel system cleaning is a service that helps keep your car's engine running smoothly by cleaning out dirt and gunk from the fuel system. It's important for maintaining performance, especially in certain types of engines.
Fuel system cleaning involves removing deposits and contaminants from the fuel system, including the fuel injectors and rail, to ensure optimal engine performance. This process is especially important for direct injection engines, which can accumulate carbon deposits more quickly.
A direct injection engine is a kind of engine that sprays fuel directly into the part where it burns, which can help it run better and use less gas. However, it might need more cleaning to keep it working well.
A direct injection engine is a type of internal combustion engine where fuel is injected directly into the combustion chamber, allowing for more precise fuel delivery and improved efficiency. This technology can lead to better performance and fuel economy but may also require more frequent maintenance due to carbon buildup.
"So doing a fuel system cleaner at every oil change. A drop or a drop in into the tank."
A fuel system cleaner is a special liquid you can add to your gas tank to help keep the engine clean. It helps remove dirt and buildup that can make the engine run less smoothly.
A fuel system cleaner is a chemical additive used to clean the fuel injectors and combustion chamber in an engine. Regular use can help maintain engine performance and efficiency by preventing carbon buildup.
"...there's an electric solenoid that bumps the linkage raising the idle. It's not the choke."
An electric solenoid is a small device that uses electricity to move parts in a car. Here, it's used to help control how fast the engine runs when the car is idling.
An electric solenoid is a type of electromagnetic switch that can control mechanical movements, often used to operate various components in a vehicle. In this context, it raises the idle by adjusting the throttle linkage.
"This is back when gasoline, octane ratings were changing and we were changing the quality of fuel and cars experienced..."
Octane ratings tell you how well a fuel can handle pressure without causing engine problems. Higher numbers mean the fuel is better for powerful engines.
Octane ratings measure a fuel's ability to resist knocking or pinging during combustion. Higher octane fuels can withstand greater pressure before igniting, which is essential for high-performance engines.
"and cars experienced, you know, dizzling and pre-ignition, detonation, a variety of gasoline performance issues..."
Pre-ignition is when the fuel in the engine ignites too early, which can cause knocking sounds and potentially harm the engine.
Pre-ignition occurs when the air-fuel mixture in the engine ignites before the spark plug fires. This can lead to engine knocking and damage if not controlled.
"and pre-ignition, detonation, a variety of gasoline performance issues..."
Detonation is when fuel explodes in the engine at the wrong time, which can damage the engine. It's usually caused by the wrong type of fuel or timing issues.
Detonation is an uncontrolled explosion in the engine's combustion chamber, which can cause severe engine damage. It often occurs due to improper fuel or timing.
"It was just an idle of solenoid is what it's called."
An idle solenoid helps control how fast an engine runs when it's not being accelerated. It adjusts the fuel and air mixture to keep the engine running smoothly.
An idle solenoid is a component in older carbureted engines that adjusts the idle speed by controlling the air-fuel mixture when the engine is idling.
"Now if this was an AC car, that was designed to bump out when you turn the AC on..."
An AC car is one that has air conditioning. When you turn on the AC, it makes the engine work harder, so sometimes the engine speed needs to be increased to handle that extra load.
An AC car refers to a vehicle equipped with air conditioning, which requires additional power from the engine. The idle speed may need to be increased to compensate for the extra load.
"You'd probably find it online at some of the carburetor rebuilders and some of the vintage car places."
A carburetor is a part of older cars that helps mix air and fuel so the engine can run. It's like a blender for the fuel that goes into the engine.
A carburetor is a device in older vehicles that mixes air and fuel for the engine. It was commonly used before fuel injection systems became standard in cars.
"... would look in some of the catalogs for cheveller Camaro because they have it as well. So, you know, it's ..."

Subwear in the mountains of Pennsylvania. And the quiet spot that no one can find. The car doctor's broadcasting remote live today. We're trying things out. We've gone a little bit west of New Jersey. And that's where I am. It was a great ride out here. The Pennsylvania Turnpike moves along very well at 85-90 miles an hour. As you kind of do that speed, trying not to get run over because that's the way it is.
And we're here doing radio today in a remote location hidden and unknown to everyone, including the government. So maybe this will be the future time we'll do government underground radio. But I had an experience this week that I wanted to talk about. And it's funny how we all try to go about communicating. I had to get a radio repaired. The Thunderbird, the CD player died. So I had to get the CD player repaired. And I took it into the repair center.
You know, I went to pick it up on Thursday, Friday, whatever day it was. And Mary, at the counter, started talking to me and we started chatting. And she said, oh, you're a mechanic. And I said, yeah. And you know, as I'm getting ready to walk out the door, my radio was coming around the corner. And she's asking me, you know, all sorts of question. And, you know, one of the questions was, are you any good?
I don't know how to answer that question. Anytime anybody asks me, am I a good mechanic? Because I just, I don't know how anybody would answer that. I told her I was terrible. I said, I'm a bad mechanic. I just kind of, I just kind of cheat and do the best I can.
And she said, wow, she said, you don't have a great opinion of yourself. And I said, well, no, not really. I said, just that usually the next question is, are you honest? And I said, this way, I figured if I tell you I was a bad mechanic, you wouldn't ask me if I was honest, I would avoid the second question because you would know that who would in the right mind would say they're a bad mechanic if they weren't.
And she's like, oh, she goes, well, she, and she was confused.
So I gave her my name and I said, Google my name, she Googled my name and she went, oh, wow, you're the car doctor.
She said, and this is the part that I don't understand because you were kind of half kidding around having this conversation. And she said, because you're a celebrity, are you expensive? And I was walking out the door because my radio had just shown up and I said, you know, it's not a matter of if I'm expensive or not.
I'm going to fix it right. Isn't that really what counts? Isn't that what you're looking for? Why, why weren't you with your last mechanic or why aren't you there anymore? She didn't have an answer for that.
It doesn't matter who works on your car in a sense. You know, why are you there? And I think you have to answer that question first time because everybody always says, or a lot of people always say, they're looking for a new mechanic.
Well, why are you looking for a new mechanic? What is it that you're looking for? And you know, if you, and we have this conversation a lot, you and I, we talk about this and we say, is it price? Is it, is it punctuality? Is it, is it honesty? Is it, you know, potential or the ability?
And I think it's all those things, but somewhere they has to come up in some kind of a stacked order. I really do. I don't think it can be. You're looking for all of it because it can't be. You can't be the cheapest, the fastest, the best.
You know, the most flexible, it just doesn't work like that. There's just too many variables in the automobile repair game. There's too many things, there's too many things that have to go right in order for something to be completed correctly.
So I don't know if that's the right question to ask anymore. Are you a good mechanic? Are you an honest mechanic?
I think the, I think the better answer is, are you capable? And I think that's what you need to really be talking about and saying to yourself, you know, is it, is it the ability to fix the car?
I think that's where you have to modify your language and be ready for that. So, but in any event, Mary went out the door and, you know, off she went and it was good and we kind of rolled along. So I just thought I would share that with you and some for another. I see the phones are lit up.
Tom, are we ready to go to phones here and remote? Yeah, let's go to John in Virginia. See what's going on here, John. Oh, no, John's not there. John's not in Virginia. So I'm not sure what's going on there.
But in any event, going back to my story about picking a mechanic, yeah, that's.
That's what we get, right? It's.
Um, it varies like that. So had a nice ride out coming out to PA. It, uh, I discovered, you know, the road being a very unforgiving place, you know, the way things just move along on the term pike.
And, uh, took the big plow truck. It was great. The plow truck kind of went from getting its 11, 12 miles to the gallon around town to all of a sudden it got 26 miles out on the highway. I have to take more road trips, I think. I think that's probably the better way to do it.
Um, so, but, uh, in any event, I think, uh, Tom is ready for me now. And, um, let's pull over and let's, uh, let's, let's jump. Let's see if we can get a phone call up. Tom, we, uh, oh, don't take the call yet. Okay.
Well, what, Tom, let's pull over, take a pause. And, uh, let's do that. I'm running any in the car doctor 855560 9900. We'll be back right after this. Don't go anywhere.
My fitness is important, but sometimes I need to do a little roll call and adjust my routine.

Hey, let's, uh, let's go to John and Virginia, 20 Honda Fit, Mass Air Flow Center, full. John, you're out with the car doctor. What can I do for you?
Hey, I recently purchased the, it's actually a Nissan Kix. It's a 2020 Nissan Kix. Ok. And it doesn't matter. Car is a car.
Exactly. Um, came up with a P0101 or place the Mass Air Flow Center. I have a really old scan tool and I'm unable to do the calibration.
And I was hoping that doing a drive test would calibrate itself. Is that possible?
When you say calibration, what do you mean calibration?
I looked up on YouTube. They say you have to do a calibration of the system. I'm assuming that I don't know.
They're probably talking about that you've got a reset fuel trim. So let's, let's go back when you, when you had the old Mass Air Flow Center in it, or the original Mass Air Flow Center in it.
Did you do any testing? Or did you just happen to randomly change it?
So like I said, it was recently, recently purchased. I took it in the dealer. They said it wasn't under warranty. So they said it was a Mass Air Flow Center. I replaced the Mass Air Flow Center.
It went out within a week. I replaced it again because it was a P0101. And then I researched on YouTube and it says you got to do some sort of calibration.
Okay. So here's what I want you to do. Take your, take your scan tool.
You know, your scan tool reads an OBD2 language. Right. I want you to hook your scan tool up. And I want you to look at calculated load.
All right. As a PID.
Okay. With me. And what, what size engine is in this car?
I don't know. All right. It's like daughter's car. I don't know.
All right. So whatever it is, a 1.5, a 2 liter, what size, what size engine this is. And then I want you to go for a road test, warmed up, closed loop.
And I want you to look at a couple of things. I want you to see what, what fuel trim is number one. All right. And, and where's fuel trim? Short term, short term, short term, long term.
But calculated load is our, is our key denominator there. If this is a 2 liter engine at idle, we're going to see roughly 1.8 to 2.5 grams of air flow per second or calculated load.
If it's really higher, really low, then maybe I've got a mass air flow out of calibration. Maybe that's a separate issue.
I could also have a torn intake duct. I could have a restricted air intake. All right. And then where did you get the mass air, where did you get the mass air flow sensor from?
Advanced auto, and it's exactly like the original.
Well, it'll look exactly like it, but it's ability to read, you know, depends on how good the electronics are internally.
Yeah.
I also figured out it's a 1.6 liter.
Okay. So at idle, calculated load, looking at calculated load, we should see 1.4 to 1.8. If I saw a 2, yeah, that's not so bad. If I see 3.
And the air intake duct is good, and there are no vacuum leaks. And the rest of the vehicle is mechanically sound. I'm going to say you just got another bad mass air flow.
I'd be curious now that you've got three mass air flows included. Could you turn in the original? Did you have to turn it in for a core?
I did. Well, I have to turn it into so warranty issue.
Well, no, the very first one, the original one you had.
The one that came with the car, do you still have that? I do not have that.
Okay. So you only have the one mass air flow that's in the car.
Correct. Right. Yeah. See, the problem is you replaced an OE part, didn't do any testing.
And now you've got to start the test, but you're testing with an unknown part of unknown quality.
Yes, sir.
Right. So got to do the mass air flow test. Got to see what calculated load is. Is calculated load correct?
Because if it's correct at idle and you're still getting the fault, then I'm going to say maybe it's another bad mass air because it's out of range at higher end.
I'd also like to see what fuel trim is as you're cruising down the road.
Does it go excessively high? Does it report excessively out of range?
All right. It's kind of odd to have three bad mass air flows.
All right. There is no calibration test I'm aware of other than resetting memory and fuel trim and then going for a ride.
Okay. And maybe maybe that's what you're reading on YouTube. But sometimes YouTube University will lead you down the wrong path.
So I would be cautious about what you're doing there.
Yes, sir. Thank you.
Now at least you've got some knowledge. I would go and look at that calculated load and see what that does.
How how close or how inaccurate is it?
And then you can call me back next week. We can talk a little bit further about it and make some better decisions. All right.
Yes, sir. Thank you very much. A calculated load and fuel trims.
Right. Yep. Absolutely. All right, John.
Yes. There are thank you so much.
You're very welcome.
Yeah. Again, I hate the idea of just.
You know, blind changing apart. Let's do an email from Al.
Hey, Ron, I own a 2024 Toyota Highlander.
What recommendations would you make for fluid changes? Another maintenance item.
The engine is a 2.5 liter with a supercharger.
I believe Toyota's recommendations are too long if I want to keep the car from more than 10 years.
Current mileage is 24,000. Thanks, Al.
You know, Al, I agree. I'm not crazy about the manufacturers, you know, fluid changes in maintenance lists.
And especially a supercharger, turbocharger, I think is what you're trying to say.
You know, they work harder. They work real hard. They build a lot of engine hood, under hood engine heat.
And I think you really want to take a look at all the fluids.
A big fan of oil changes every 5,000 miles.
I think it's an absolute must. I think it's something you just need to do.
You know, I disagree completely with the 10,000 mile oil change interval.
As you well know, a good quality filter. Absolutely.
Trans fluid at 50.
Trans fluid between 50 and 60. Dressed to the driveline fluids.
You know, rear diff front diff.
The front transfer case, if we want to call it that, or the power takeoff unit on that particular car, has less than a quart of fluid in it.
And you can't imagine the abuse that it's taking in terms of heat and power distribution.
And they just put such a small unit in there.
And they have for the longest time that, you know, all the driveline fluids at 50.
I like coolant at 5 years. I think that's mandatory. I think fuel system cleaning at 30.
Where you're going to hook up the physical machine and clean the rail.
And, you know, perhaps a kit from CRC to do a fuel system cleaning to make sure it because that should be a direct injection engine.
And in all likelihood, that is a port and direct injection engine.
So doing a fuel system cleaner at every oil change.
A drop or a drop in into the tank.
I think that's mandatory as well.
You know, as complicated as the cars are getting, it still comes back to maintenance and fluids and the things you're talking about.
And if you want to keep the car 5 years, 10 years, or somewhere in between or beyond, it comes back to fluids being the vital part of keeping the car and getting it there.
And it's just so gosh darn important. But just stay with the fluids, like I said, Al and I think you'll see that you'll get that result.
So let's do another piece of where are we?
Hey, Ron, this one comes to us from Robert.
Robert's got a 70 in pallet with a 352 barrel. Sometimes it's as if I can't knock off the choke.
There's an electric solenoid that bumps the linkage raising the idle. It's not the choke.
That's on the power steering manifold coming off on the top of the manifold passenger side coming off on the top of the manifold.
No matter how long I let it idle, the solenoid doesn't release the linkage.
This car doesn't have and never had AC. What is this and what's it for and what's it called so I can replace it?
That's actually there on a non AC car in 1970, Robert.
Because what they did was that's supposed to close the throttle.
The idea was that it would close the throttle and prevent the car from doing run on.
This is back when gasoline, octane ratings were changing and we were changing the quality of fuel and cars experienced,
you know, dizzling and pre-ignition, detonation, a variety of gasoline performance issues and they figured out that if they closed the throttle plate,
they would shut off the air supply and cause the engine to shut off quickly if it was having any of those issues when you turn off the K.
I don't know that you need that anymore because obviously gasoline has changed a few times in the past 60 years, 50 years.
And I would set this up on the base idle screw off the carburetor itself and then use that as a slight bump up.
And I would play with it and adjust it. It's something that was there as an emission control back in the day and I don't know that it's mandatory anymore.
It was just an idle of solenoid is what it's called.
Now if this was an AC car, that was designed to bump out when you turn the AC on and provide an additional RPM for the engine when it was under the load of air conditioning.
So, you know, a completely different story, but this is a very mechanical car.
This is a question of, you know, can you make it run OK, just on base idle screw that back to base idle screw off a touch, use that idle up to allow the throttle plate to close more when you release it and then it'll have its curb idle and it's bump up idle if you want to think a bit like that.
That's all you need and that solenoid is probably not available too much at auto parts stores anymore.
It was just an idle of solenoid, single wire mounted on the side of the carb.
You'd probably find it online at some of the carburetor rebuilders and some of the vintage car places.
You know, I would look in some of the catalogs for cheveller Camaro because they have it as well.
So, you know, it's a it's a fairly common item across the board for general motor products of that era and that vintage.

Trainer Games on Prime Video January 8th. Watch the trailer on trainergames.com.
Hey, we're back. 855-560-9900.
Let's go to Tom and Utah, O2 Toyota Sequoia. What's going on, Tom?
Well, I engage the four-wheel drive low.
And then when I went to this is a short story. When I went to disengage it.
It appears that it's partially disengage.
It allows me to reach speeds.
But when I turned, you can tell that the front wheels are still engaged.
I have an indicator on the dash that shows the four wheels.
And usually when it's in four-wheel drive, those are all green.
Those have turned off, but there's an orange dot in the middle of that that stays on in fact it's blinking.
I'm hoping maybe there's some type of vacuum issue or something that's maybe not an entire rebuild.
Yeah, I agree. It sounds like the front axle is partially engaged.
Hi, mileage on this unit.
Yes, sir.
Have you tried backing up with the unit in two-wheel drive to see if it releases?
I have. I've tried backing up when I disengage in reverse.
Try to doing it in neutral.
Right.
Moving forward and backing up, you know, those different things.
Because in the past, that has worked.
But this doesn't happen very often, but now that it's happened, I've been able to get it out in the past.
But now it's happened.
It won't release.
It won't release. That's correct.
Have you looked at the fluid on the front diff or the transfer case at all?
I have not.
Just fluid level or does either one of those show metal particulate not to say the ugly word?
Amen.
Yeah.
You know, is it, you know, what are we chewing up?
Because if you continue to drive this, you're going to break something even more if that's possible.
Right.
And that's a concern.
You know, even if you pulled the front drive shift, something's locked on.
And, you know, in a case of this, I don't even know if I would tell you to start disengaging if there's vacuum controls to try and manually shift it because it just sounds like something's broken and it really should get fixed because you can't count on it.
You can't trust on it that it's going to release if you ever had to put it back in in the future.
Right.
Yeah, it's only, it's only low.
It's not where we'll drive high.
Right.
It's only effective in the low.
Have you tried shifting into four-wheel drive high?
Yes.
Yeah.
And it won't go.
Yeah.
Right.
It won't release.
I mean, it goes.
It won't release.
Right.
You can't tell that it's in low until you make a sharp turn and you how it grabs when you make a turn.
Yeah, it hops.
Right.
It hops.
It sounds like the front diff is locked on.
So, you know, there's an actuator there that if you were to remove it, you might be able to get the piston to slide out and release it.
But then the problem is, does it happen again?
And if, you know, if, in other words, what I'm saying is if you can't trust it to use it, then take it apart and fix it, right?
Yeah.
You know, as much as you don't want to do it because you're probably going to tell me there's 300,000 miles on this thing.
Yeah, 260.
Yeah.
So, you know, isn't, isn't this a case where if you're going to keep the truck, you might as well find out now what's bad before you really do, if it's possible, more serious damage and it's going to cost you more money.
For sure.
Yeah.
You know, I don't think I would drive this at all or much longer, Tom, because you're only chewing something up.
Okay.
I'm almost up.
Yeah.
I'm almost certain you're going to go check front diff fluid and take a magnet and fish it down around in the bottom and you're going to come up with shavings.
But it sounds like it sounds like the front diff is locked on.
And, you know, maybe you pull the front drive shift, put the transfer case in neutral.
If the transfer case spins, then, you know, the transfer case is okay.
And then your problem's in the front diff and break it down that way.
Okay.
And notice, you know, at least, you know, then what you've got to take apart, you know, do you have an actuator that stuck on on the front?
Take a look at the way the system actuates up on the front is the actuator not releasing.
And if you were to disassemble that, does that allow it to release?
And it's maybe it's more of a control thing than the actual diff itself.
Right.
Yeah, I'm following you.
Right.
Got to take something apart, my friend.
I know you don't want to do it.
I know that's why you called me.
There's no magic bullet for this one.
It sounds mechanical.
Yeah.
Just trying to look at the colors hoping maybe you had some vacuum secret, but I don't think we do it.
No, I don't think you do.
I think you've tried them all.
Like I say, you may find an actuator that stuck on, but in the meantime, how much have you driven it at this mileage?
Have you heard anything at the very least you owe it?
You owe it a check of the fluid.
And fluid level fluid condition, that kind of thing.
Yeah.
I may have only driven it 10 miles just trying to, you know, do different weird reverse types of things, but I haven't driven it much.
Right.
Yeah.
So listen, it won't matter how much you've driven it.
The answer is going to be how much will it tolerate at this age of mileage?
That's true.
Yeah.
Take it apart.
It's worth keeping.
Yeah, I agree.
It's been a good ride over all of us.
Yeah.
You know, it's to go and replace it now.
When you look at the price of a new one, all of a sudden, overhauling every driveline component in the truck looks like a bargain.
Hey, man.
Yeah.
So.
Yeah, this one's probably around 90 to 100,000 new.
Right.
Oh, yeah.
You know, everything is so it's, you know, it's not a question of what you should, what should you do?
It's a question of how much should you do?
Yes.
You know, and do it once and get it over with.
So.
All right, kiddo.
Yeah.
Enjoy your show.
Thank you for all you do.
You're very welcome, sir.
Yeah.
I appreciate you being there today.
You be well.
Yeah.
It just kind of comes down to, can we, can we fix it?
And, you know, on the other side of it, Tom, if you're still listening, fix it now.
We can still get parts for it because it's 23 years old.
And, you know, drive it another 20 years.

And we're back at 555-6-0-999-00 on any of the car doctor.
Let's go to Joe and Iowa.
Oh, two Dodge pickup.
Joe, welcome to the car doctor.
Sure, how can I help?
Yeah, good afternoon fellows.
Hey, so my kid, I got a couple things I want to ask you about.
Sure.
One of my kids.
One of my kids got, yeah, the 2002 Dodge.
It's a 3,500.
It's got the Cummings diesel engine.
And he started to start the other day.
It sits for quite a while.
The battery's your dead.
So he went on, got two brand new batteries.
He stuck them in and he went to start it.
I don't remember.
In a few days or something.
And he couldn't get it started.
The batteries weren't dead.
He checked it with voltmeter and they were pretty much dead.
So I took a look at it.
Just glance.
And I see, well, look like he might have left the light on in the cab.
So I shut that switch on the rotary switch.
I shut that off and think, well, you know, that must have been the problem.
You know, pulled the batteries down.
And it does have two batteries.
And then I charged them, looked at it the next day.
They were about down to less than a volt.
So I thought, well, that's interesting.
One of the way else is going on.
So then I checked the radio and the radio switch was on,
but there was no volume coming out of it.
So I thought, well, maybe by chance, maybe the radio pulled down.
I didn't think the radio would have any voltage going to it
with the key out of the ignition.
But it should never.
Yeah.
Right.
It shouldn't.
Okay, that's interesting.
So I went ahead and shut the radio off, rotary dial radio.
I shut it off and charged batteries again.
The next day, the battery stayed.
I never could get a full 12 12 and a half volts on the batteries.
First of all, what are you charging the batteries with?
A trickle charger?
You know, at that time, I had a charger that was putting out a 6 amp charger.
Okay.
You really need to charge to correctly charge a battery,
such as what's required for that Cummins diesel.
You're really going to need a professional grade repair shop charger.
All right.
And you should be, you know, are you disconnecting the battery cables
when you're charging?
No, I left them hooked up and I charged them together.
No, disconnect them and charge them individually or go buy a real charger.
All right.
It'll take, it'll take too long.
Besides the fact that if you leave it hooked up and there's a draw in the vehicle,
you're pulling against the charger.
Yeah, I figured that too.
All right.
Yeah.
So, you know, the first step is you've got to get the chart,
you've got to get the batteries up to correct the level.
It may not happen overnight with a, with a low amp charger like that.
All right.
It may take a couple of days for each battery.
Oh.
Yep.
I'm sorry.
At what rate, uh, amp reach rate where you talk and it might take that.
Well, you know, we're, if we're, if we're in the shop,
I'm rolling it over to the automatic charger and it's going to set the charge rate
based on the internal resistance value of the battery and its capacity.
That's what I'm saying.
Six amps, six amps is such, is, is on such a low scale.
You know, the professional grade charges will run anywhere from 20 to 35 amps in these batteries.
Today, to bring them up to speed and then it will, it will, you know,
tailor it down as they get closer to the top of their charge.
Okay.
You're trying to empty the ocean with a teaspoon.
Okay.
It's going to, it's going to take a while.
All right.
Okay.
So, you know, that's, that's number one.
Number two, once you get the batteries up to charge, do you have a DVOM,
a digital volt ohm meter, something with a milliamp scale or an amp scale in it?
Yeah, I got a, I got a volt meter.
Okay.
So, let's set it, let's set it on amperage.
Let's set it on milliamps and let's put the meter in series.
And we can do this off of one battery, leave the other one disconnected.
So, it's not to provide an alternate power source and confuse things.
All right.
Okay.
And, and let's just, let's just measure for draw.
Do we have a draw on this vehicle?
The rule says, the rule says that you have to have less than 50 milliamps
in order for the vehicle to be considered okay.
On a draw, you need less than 50 milliamps.
Less than 50 milliamps.
All right.
And if you find an excessive high drop, you know, if it's there,
it may take a while to, you know, bleed down depending upon the amount of computers in O2,
not a whole lot of computers in this thing.
But within a half hour to 45 minutes, we should see under 50 milliamps.
And if after that 45 minute period we still see, you know, three, four, seven, eight amps,
then one of the time we're going to pop a fuse.
Just take a fuse out of, start with the underhood fuse box
and then work your way into the interior cabin fuse box.
Right.
And one of the time taking out, put it in.
Does it make any change?
One of those fuses is going to show us a circuit that's drawing.
Let me ask you this question.
Let me, let me ask you this question.
Is the radio and aftermarket radio?
You know, I'm not for sure.
I'm not for sure.
Ron, yeah.
Take a look.
If that radio is aftermarket, if it looks like it was installed by the previous owner,
you know, I probably start there.
I see a lot of problems with the aftermarket radio or the install that becomes an issue.
Yeah.
Yeah.
Okay.
I just didn't think there'd be any voltage to it.
You know, I was surprised when it actually kept a pretty good charge on it after the next day.
But well, let me, can I ask you?
I'll tell you what.
Sit tight.
Sit tight, Joe.
Let me pull over.
Take this pose when I come back.
We'll finish up.
All right.
I'm Ron and Annie in the car doctor.
We're back right after this.
And Doug.
I'll put a horrible call.
Hey, Ralph, open your eyes.
Ralph, you're really not going to call that.
Come on.
Hey, Ralph, why don't you customize your car insurance with Liberty Mutual and save money?
I don't think you get what we're doing.
Sure I do.

Hey, we're back!
Raining in the car to operate.
Fire 5 5 6 0 9 9 0 0.
Joe you're still there, Iowa.
Yeah, still here.
Yes sir.
A couple of questions.
You got a couple of minutes, Joe.
Go ahead.
Okay, I thought, he had any checkered this morning my kid,
he said had 11.60 volts on the batteries.
I thought that would need to be enough to crank it kind of slow,
kind of slow but he said it wouldn't do nothing. How much voltage? A battery is considered
under voltage at 12.1. A standing 12 volt battery should have 12 and a half volts to it.
Yeah, that's what I figured about 12 and a half. So that's the bottom line.
Okay, okay. And I looked at my volt meter and it doesn't, I got an amp AC scale but no
DC scale on it. Is there a way to convert it or you're going to have to get something that's
milliamps. Does it go to milliamp? In AC it goes to 200 milliamps I believe in or
10 amp setting 200 milliamps. Oh, there is a DC scale and I see it so I see it now.
Okay. Yeah, 200 amp. Right, so that's what you want. You want to put that on
milliamps and you're looking for a 50 milliamp draw or less. And I would think on a
no two Dodge diesel, you're probably going to be a lot less than 50 milliamps.
There's not a lot of computer electronics on that vehicle. How do you, how do you
look that up for to check for a draw? You're going to disconnect the negative battery
cable and put the meter in series. I'll go from the negative post to that.
Right. Yeah, so, so disconnect the other battery. So it's out of the equation.
Then you're going to just connect the negative battery cable and you're going to put one
lead of the meter to the post and one lead of the meter to the cable.
Okay, to the negative side. Yeah, to the negative side. I like working with the negative side.
Let's chance to spark and something. Okay, okay. I see what it just just see what it does.
And then just watch your polarity if it reads negative reverse your leads. Yeah, yeah.
Okay, how much time though, how much time do you, when you take that reading, is it just
inconvenient? 45, like I said, like I said to you before, Joe, have powered a 45
minutes. You should see a drop off under 50 milliamps. Again, depending upon the
amount of computers on that truck, an hour is the maximum. But, you know, that, that 30
to 45 minutes should do it. And I would start with looking at this radio, if you suspect
that maybe take that fuse out first and see where you go.
Appreciate the call, Joe. I'm here next week. If you need me, I'm running any
in the car doctor. It's been a pleasure until the next time. Good mechanics
aren't expensive. They're priceless. See you.
