    Currently in school to become an automotive technician, and my goal is to get into a Porsche dealership. Anyway, turning wrench is easy. It’s easy to take an engine out of the car when you have the fundamentals. What I’m seeing nowadays is that technicians aren’t paid for their wrenching skills, they are paid for their knowledge and troubleshooting. I absolutely sucked at electrical at first, I stayed in class an extra hour because I couldn’t understand the circuits, and in my school we built them, wiring the headlights, taillights, hazard lights, turn signals, anything lights in a car we wired. I just couldn’t figure out the difference between parallel and series circuits and the different resistors we needed. After many more hours out of class, I decided I’d just mess with my car, follow the diagrams and just study until I got the hang of it. Finally, it clicked and it all made sense, and when it made sense, diagnosing became a breeze. Definitely a great skill to have.

    I was raised by a mechanic who was highly skilled and also done most of my own work yet know little about electrical. I’m convinced that 99% of mechanics do not know advanced electrical such as finding a short. Someone skilled will find it quickly. In Houston I only know of one that’s at a Buick dealership and they say he’s a rockstar. If the young mechanics would learn all electrical they would be worth $150k a year easily because nobody knows how to do it. Great video bud!

    I used to hate doing electrical work, until I watched a friend go through my rear lighting wiring...and figure out why my rear lights weren't functioning properly. It was meticulous...unwrapping tape...testing...removing useless stuff that others left behind...and learning to crimp wiring properly. When he did it, I realized I could do it also. Was just a matter of focussing on the problem at hand.

    Good vid for the beginner. A power probe, or similar item is a god sent. I have the $300 Fluke meter...BUT. I always go to my $5 Harbor Freight tester. Just the simple pointy tip with the incandescent bulb. Never get the LED tester. You can judge the current by the brightness of the incandescent. Can’t do that with the LED.

    I generally use both a multimeter...or a test light. The thing that gets in the way sometimes is how short the leads are....especially if I'm working on the tranny wiring or something else in the middle or back of the truck. I end up clipping together some clip extensions. Wiring is definitely a challenge, especially when dealing with stuff that goes through larger bundles of wiring by the ecm or relay box under the hood. I'm definitely no expert at all on wiring, but with persistence I usually figure things out. I recently had a no crank no start on my truck, after it was off the road for a year and a half....after I got engine rebuilt and rebuilt the tranny myself. At first, it would crank with a screwdriver over the solenoid terminals...but then I got nothing. Ended up finding a break of the solenoid signal wire at the starter.....and also had a new neutral safety switch that was faulty. That neutral safety switch was a real block...because I couldn't believe it would be faulty...lol.
