I’ve got a '72 Plymouth Valiant. I just replaced the alternator and voltage regulator after the alternator started making that death noise and smell. The new alternator configuration slightly different, but as best I can tell I’ve wired it correctly.
That said, now when I start the car it runs smoothly, but in less than a minute the wire from the alternator to the voltage regulator heats up to the point that it is melting. I’ve since replaced the melted wire, but I’m hesitant to just start the car because I don’t know what caused the problem in the first place.
Did I wire this wrong? Could another part be damaged and causing this?
