Question on how to wire up a internal voltage reg alternator.
This question is actually for my 66 Nova SS but I am sure it would be the same as a Vette. The guy I bought my Nova from had started converting the alt. over to the internal voltage reg style. I am getting the car wired up today and trying to get it running but I am missing a wire somewhere. I have the large red wire that get bolted to the alternator and I have a brown wire coming out of the harness, I need to know where that brown wire goes and where the other wire for the other post come from etc. Thanks for all of your help!! :cheers:

Go to Lectric Limited
They have a pretty cheap ($20 or so) plug-in wiring adaptor to use with your existing harness.
It's almost a no-brainer! |
The problem is....the guy I bought the car from already eliminated all of the wires trying to do a 1 wire alternator and messed it all up so all I have to work with is the brown wire that I don't know where it goes and the big red wire that goes to the back and gets bolted on.

Terminal 1 on the alternator plug goes to the idiot light and then the ignition switch.
terminal 2 should connect into a hot lead some where on your wiring harness away from the battery. Horn relay, other junction block, etc. Doug |
Sounds like you are using a tampered harness. I believe the brown wire will be for the grounding brush/sense. The original external v/r provided field excitation to the original f spade on the alt. I would check your brown wire for power with batt connected and ign s/w on and off. Should not have power either way, if no power check for resistance with ohm meter; should show resistance. As a temp fix, the 10 ga red wire will connect to the batt terminal on the alt. This should be hot with batt connected. Add a 14/16 ga jumper from the hot 10ga red to the f spade. This provide batt voltage to the internal reg.
See Madd Electrical for proper wiring of the internal reg alt. brgds rene |
