About this episode

Golf self-criticism becomes a lens for diagnosing intermittent electrical problems—where hindsight bias and the “curse of knowledge” can make earlier effort feel “obvious” only after the fix. The hosts connect that emotional loop to real troubleshooting: spending “two hours” chasing a short that only shows up sometimes, then losing time without the right setup. They emphasize better test setup and tools (including scope-style alerts) and broaden the mindset for EV and modern systems like TPMS and ADAS.

Technical Too Afraid to Ask
Term

discounting the positive

"One is discounting the positive. I thought it might be like imposter syndrome..."

“Discounting the positive” means you don’t give yourself credit for good results. Even when you did well, your brain tries to make it seem less impressive.

Term

hindsight bias

"There's somewhat the same, not exactly, but one basically the cognitive biases and a loose term might be hindsight bias with my skill set..."

Hindsight bias is when, after you figure something out, you start thinking it was obvious. It can make you underestimate how difficult it was before you knew the answer.

Term

bogey

"So what happens is I score a bogey, which is one over par, and I'm looking at what if..."

In golf, a bogey means you used one extra shot compared to what’s expected for that hole. Here it’s mainly used as a comparison to explain the speaker’s mindset.

Term

intermittent short

"How many times have you had a vehicle head? And as a technical specialist, you spend two hours trying to find an intermittent short that pops a fuse."

An intermittent short is an electrical problem that only shows up occasionally. It can be tricky to find because the wiring or connection seems fine most of the time.

Term

pops a fuse

"you spend two hours trying to find an intermittent short that pops a fuse. And depending on what it is, where it is, two hours is actually really good."

If a fuse “pops,” it means it burned out to stop the circuit from overheating. Mechanics use that as a clue to figure out what electrical problem is causing too much current.

Term

meter that emits a sound

"you know, or if I would have set my meter up for the beep to make a sound, oh, it saved me some time or had longer leads on my headlight or test light or whatever so that I could have seen it while it was back there."

Some car electrical meters can beep when they detect something like continuity or voltage. That sound can make it easier to know you got the right reading quickly.

Term

test light

"it saved me some time or had longer leads on my headlight or test light or whatever so that I could have seen it while it was back there."

A test light is a basic tool that lights up when electricity is present. Mechanics use it to quickly check if a wire or connector is getting power.

Term

leads

"it saved me some time or had longer leads on my headlight or test light or whatever so that I could have seen it while it was back there."

In electrical testing, leads are the probe wires/clips that connect your meter or test light to the circuit. Longer leads can improve visibility and reach when the connector or wiring is hard to access.

Term

incandescent

"I might, you know what, I need to manufacture some leads for my test lights, whatever they are, test, you know, a regular incandescent,"

Incandescent bulbs make light by heating a tiny filament until it glows. The type of bulb matters because electrical testing can behave differently than with newer bulb types.

Term

scopes

"something like that, you know, set up your scopes, right? Pico, we can set it up to do some pretty cool stuff to alert you of certain phenomenon"

A scope is a tool that shows electrical signals over time. It’s helpful when the problem happens only sometimes, like a signal that flickers.

Term

Pico

"something like that, you know, set up your scopes, right? Pico, we can set it up to do some pretty cool stuff to alert you of certain phenomenon, like current exceeding a certain amount or vice versa"

Pico is a brand of diagnostic tools (often oscilloscopes) that can help you see electrical signals. In this context, it’s about getting alerts when something goes out of range.

Term

current exceeding a certain amount

"Pico, we can set it up to do some pretty cool stuff to alert you of certain phenomenon, like current exceeding a certain amount or vice versa"

It means the electrical current is going higher than it should. Some diagnostic tools can warn you when that happens so you can find the problem sooner.

Concept

wild goose chase

"did, you didn't make any gross errors, big errors, big screw ups, you didn't go on a big wild goose chase or anything like that."

A “wild goose chase” means you keep looking in the wrong place and waste time. Good diagnostics tries to avoid that by staying focused on the most likely causes.

Concept

rabbit hole

"You didn't go on a big wild goose chase or anything like that. You didn't go spiraling down a rabbit hole."

A “rabbit hole” is when you get stuck chasing one idea too long. In car diagnosis, it’s a warning sign that you may need to change your approach.

Term

bulletin

"it's no different than a bulletin, instructing you to go look at a certain area, because it's a known problem, fine."

A bulletin is an official notice that says, “We’ve seen this problem before; check this area.” It helps mechanics skip guesswork when a fault is known.

Term

transmission

"a mechanical specialist pulling that transmission out, following the procedure, step by step, and then realizing I didn't have to take that out."

The transmission is the part that changes gears and sends power to the wheels. Taking it out is a big job, so the point is not to remove it unless you really have to.

Car

Master Tech

"...ouse. Are you the entry level tech or are you the master tech, right? As quote-unquote experts, we kind of have..."

“Master” here doesn’t sound like a car name. It’s describing a person’s level of skill—like being the top or most experienced technician. The conversation is about diagnosing problems and who should handle them.

Term

high voltage system analysis

"Pico Technologies EV diagnostic kits are your all in one solution to safely and efficiently service any electric or hybrid vehicle from comprehensive high voltage system analysis and installation testing to guided step by step procedures."

Electric cars have parts that run on very high voltage, which can be dangerous. “High voltage system analysis” means using a diagnostic tool to check that those electrical parts are working properly and safely.

Term

installation testing

"Pico Technologies EV diagnostic kits are your all in one solution to safely and efficiently service any electric or hybrid vehicle from comprehensive high voltage system analysis and installation testing to guided step by step procedures."

After you install something on a car—especially on an electric car—you need to test it to make sure it was connected correctly. “Installation testing” is the step where you confirm the job is done right and the system works safely.

Brand

Autel

"This episode of diagnosing the aftermarket A to Z is brought to you by Autel. Autel is a global developer and manufacturer of award winning professional automotive diagnostic tools and service equipment trusted by technicians, educators and shop owners across North America."

Autel makes professional diagnostic tools for car repair shops. In this episode, they’re described as helping technicians troubleshoot modern systems like tire pressure sensors and driver-assist features.

Term

ADAS

"When questions arise, you're working with people who understand the vehicles, the procedures and the real world demands of modern repair, whether diagnosing complex drivability concerns, servicing TPMS systems, validating repairs or working with ADAS and advanced safety technologies."

ADAS stands for the driver-assist features in newer cars, like systems that help with braking or staying in the lane. After certain repairs, you may need special diagnostics to make sure those sensors are set up correctly.

Term

TPMS systems

"When questions arise, you're working with people who understand the vehicles, the procedures and the real world demands of modern repair, whether diagnosing complex drivability concerns, servicing TPMS systems, validating repairs or working with ADAS and advanced safety technologies."

TPMS is the tire-pressure warning system in modern cars. It uses sensors to tell you if a tire’s pressure is off, and shops may need to reset or relearn the sensors after service.

Term

OEM procedures and standards

"Autel tools are engineered to support accurate, efficient repairs and strict accordance with OEM procedures and standards. To learn more about Autel and their diagnostic solutions, visit Autel.com."

OEM is the carmaker itself. “OEM procedures and standards” means following the exact instructions the manufacturer says to use for diagnosing and repairing the vehicle, rather than guessing.
