Re: one more try... generator light on
Ok guys, not so good after all, so this is what Ive done now. Next day, dead battery. I charged the battery real good, unhooked the charger and started looking for a problem. I disconected the ground wire from the battery and rad support, put a test light between the battery and ground wire. Light came on as you would expect. I pulled every fuse, no luck. Unplugged every wiring connection that I could find ( coil, oil sending unit, temp sending unit, etc.) nothing. I unhooked the wiring harness to the VR and no change. Unhooked the 2 wire harness to the alt. an nothing but then I noticed something. The alternator was very warm from when the charger was hooked up I guess. I unhooked the hot wire to the alternator and the test light went out. I temporarily hooked up another alternator and the test light stayed out. The one that was on the car was new... internal ground maybe??? Can bad diodes do all this??
