My generator light just came on while driving. It is on when the car is running and turns off when the ignition is off. Car is a 69' 396, with original style alt (rebuilt a year ago new everything), original style voltage regulator (A/C delco).
I've search archives and tried many things that were mentioned.
Here are some things I tried.
1) Pulled alternator apart to replace the battery terminal which was loose and showed signs of scoring on the inside of alternator. The threads were stripped (on bolt) so I had to cut off the old bolt and replace. Installed proper bolt and insulation, put back together, made sure bushings were in place.
2) Alternator was tested, checked okay.
3) Replaced horn relay
4) Replaced voltage regulator
5) Spot checked wiring harness (engine compartment)
Battery is staying charged, and the car seems to be running fine.
I read somewhere about a ground in the center of the dash bezel. Can someone describe in detail where this ground screw is, I can't seem to locate it???
Is there a simple way to check the new and old voltage regulator, I do have a tester?
Before I check the starter wires, would this affect the Gen light in any way? The starter is working perfectly.
Thanks for the help!
