Herein is my question. On my gm vehicle, I replaced the dash gauges with aftermarket gauges. So, I replaced the battery light with a volt meter. I have burned up several alternators.. Have been told that by removing battery light, I also removed the resistance from the circuit going to the alternator and thereby causing the alternator to fail. Question,, how much resistance do I need to put in the circuit to make the circuit operational and not ruin the alternator? The vehicle is a 95 S10 with the CS130 AC Delco alternator. Will resistance also drop the voltage? I really need some help here and greatly appreciate the help that you can give me. I am really dumb when it comes to this circuitry. Thank you very much.

You should ask on a car forum. – garyp Mar 7 '14 at 20:03

Woe is he who messes with electronics before understanding the design of the original system. – Carl Witthoft Mar 7 '14 at 22:05
