Bad Grounds vs Alternators
3 shops missed the problem, Eric finds it and goes to great lengths to explain why...
yeah, it is not a 7.3, but that is not the topic, it is the power system.
this car has burned up 3 Alternators, the reason was a Bad Ground to the Battery…
Short and Sweet, 29 minutes, Eric 'O is a teacher, he wants to explain why things happen.
Diagnoses is his thing, no Diagnosis and you are a Parts Changer…
I have watched him fix tons of cars without having to buy any parts at all.
Usually, he removes the Chinese stuff that was on the vehicle, and puts the OEM parts back on it, then he starts the Diagnosis process.
You would surprised at how many folks stuff the OEM parts in the new parts box, and toss it on the passenger side floorboard.

Good video demonstrating the little known or used voltage drop test. Also interesting how the problem was at the other end of the cable, not the end most assume is the only place there could be a problem.
