Re: 1970 C10 Battery/Alternator/External regulator issue

Ok, that makes much more sense now Vette. I've been stumped for a while. The initial problem I had, the wiring harness I bought was universal. At one point, I had the brown wire from external regulator up front hooked into the ignition, and that connected to the gauge cluster with the tan wires... long story short, I fried an aftermarket tach, melted another few wires when I was trying to figure out the issue... Its been a nightmare. I thought I had it all figured out when everything stopped smoking and warping, but now, after a short drive with the headlights, the battery discharges and isn't getting charged at all.

Here's my next question then.. can I build a wire with a resistor that can run straight from the #4 blade on the external regulator and plug it into the ignition switch on one of the terminals? If so, which one would be the best one to go with?
