Yeah I don’t blame you for letting that one go that definitely can be a nightmare of chasing down all the electrical faults for sure. The recommendation of taking it to the dealership is a good one but it will cost a lot of dollars to make it right again that’s if they will even work on it.

Great video! Too me, it is your decision on whether to take on a problem which may take more time to diagnose, as opposed to perhaps, repairing more other cars. It's really your call, and I would not spend anymore time on it. Your decision to tell the customer to bring it to the dealer would be the best decision for you, as a mechanic shop owner. When you come across a DIY persons mistake which causes much bigger problems, then at some point you should show the customer what they did wrong, and let them pay the price for their incompetence. Great video Alex. You are a good mechanic.

You did the right thing, sometimes you need to walk away. Two weeks ago I had to walk away from changing the rear differential on my wife’s SUV. Working my regular day job and my second job left no time for that part replacement. I brought the vehicle to my friend’s shop and had them do it. I like to guess the solution to the problems on your videos before after the first 30 seconds. I was guessing the BCM on this car. Maybe I was right but I guess I’ll never know. Do you need to tell the BCM that you installed a new battery on this car? I needed to do that on my wife’s car. Kind of weird. Thanks for another outstanding video.

As a Sr. Design Assurance Engineer just so you know in the future reverse polarity is a failure mode on the DFMEA (Design Failure Mode Effects Analysis) it is expected that people will install the battery backwards. When a car battery is connected backward, a fuse designed to protect vehicle electronics should blow. If your vehicle doesn’t have a fuse (almost all cars do) designed for this purpose, you will send electrical current backward through systems in your car, including ECU, transmission control unit, and more. If current flows backward through lights, that’s not a problem when current flows backward through electronics with diodes such as the ECU / ECM (Engine Control Unit / Module). It is not common to damage the Engine Control Unit / Module by disconnecting the battery cables. Most of them are designed to withstand reverse polarity. In the worst case, the ECU/ECM can be removed and inspected if a diode has failed. But reverse polarity does not damage anything as their is a fuse designated just for this. I heard a pop also and that is the fuse located somewhere. I don’t think that’s what’s happening, that dude didn’t pop because of the reverse polarity as the damage was already done to the other blown fuses. The pop at the ignition turn is most likely something is touching or it’s the ignition fuse.

A few years ago, a customer at my nephew's shop was recommended a battery replacement on his Mercedes. He didn't want to pay the price for the Interstate battery at the shop. A few days later the car came back to the shop riding of a rollback truck. The customer had pulled out the back seat and replaced the battery. It was tough because he put the battery backwards, so he struggled to get the cables to reach the battery post. $4000, and countless modules later, he had a good running big Mercedes sedan.

i am in the middle of a 1977 IH Scout i think that they left it switched on it had been changed to points system burned the wire in distributor back to coil then the wire from the coil back to the ignition switch. odd thing about the IH most wires are green and have numbers on them so tracing without wiring diagram to refer to would be ruff but looks like only a few wires touching the burned wire and the ignition switch and pigtail burned off. so odd orielly had switch and pigtail in stock

I hear you Alex. Electrical can be very time consuming. Especially when you have cars waiting for repairs. Some are not worth the time put into them. Because the diagnostic fee can get expensive. And some customers don’t want to pay that. Good move on that one. Doesn’t mean you can’t fix it. Just have to see the bigger picture. 👍

Alex, checking fuses is WAY simpler than using a DVOM...get a test light. If it lights both sides of the fuse it's good. If it only lights one side or neither, it's bad. Way easier than using a DVOM. Eric O with South Main Auto is fantastic for teaching electrical stuff. And you can't put a wrong fuse in man. You put a 10a where a 15a goes. That's a huge no-no, especially on modern cars. And that jcase fuse you put in is the wrong one too, may be the same amp, but it's the wrong one.
