Re: GM 3 wire Alternator in an 81
« on: Nov 16, 2016, 05:15:46 AM »
I understand the schematic but on mine, I have more and different color wires than what that diagram is showing. Did you guys have the external regulator? I have the 40 amp three wire plug alternator with external regulator. Did you unplug the regulator and wire off of those wires or the wires going to the alternator? I have a green, yellow and white with black stripe on my alternator plug. On the plug that goes into the external regulator, I have two yellows, a red, a green, and a white with black stripe. I'm assuming tie the two yellows together, and use the red but what would be the wire for the "S" sense wire, the white with black stripe or the green?
