wires off alternator keep melting/burning up
« on: August 08, 2017, 11:54:04 AM »
hey guys, installed a new alternator/voltage regulator and my white wire off the alternator keeps melting, the orange one looks a little burnt too but cant tell if its just cause the heat from the white one or not, I don't know much about wiring, what does this wire go to?

If you have a white and a green wires plus a stud/nut, the green wire goes to the coil, the white wire goes to a 12 volt source, or you can attach it to the stud/nut along with the large wire that goes your 12 volt source. This is what I've done to my own cars and is just the way I did it.

The alternator wiring could care less about car size because the wiring for the alternator is the same in all Pintos. The size engine and AC only count in picking the power out putt of the alternator, NOT the wiring. All alternators made today in the USofA are three (3) wires and one wire (1). Or so I'm told.

You might try running a ground wire off of the alternator case if all else fail's.
