1990 Chevrolet K1500 Cheyenne 5.7L Alternator Wiring
Posted to GM Electrical on 9/8/1999

Hello group. I havent seen this before. The charging system works fine untill overdrive kicks in. When this happens the charge light comes on and it quits charging. What I have found is on the brown ignition feed wire I loose voltage. It drops to 0 volts.....
