My gen light came on in my '67 and I found out my alternator was bad. I replaced the alternator, voltage regulator, and the battery and my generator light is still on. It goes out when I give it gas but once the car slows down it comes on again. Anything in particular that would make this happen?

I tried to make sure the alternator belt was as tight as possible when I put it on, and the alt looks the same with a red wire for battery, plus the plug with the blue wire and the white wire. The back of the alt has two prongs for that plug, so it must be a 3 wire alt.

Are you sure it was the alternator that is bad? a voltage regulator can cause the same problem if it's stuck. You may want to replace the voltage reg. and see what happens. It's not a very costly part. Around $12 here.

Since you said you already replaced the alt., reg., and battery you might want to check the connections at the horn relay. Make sure they're clean and tight. If there's a wire that goes to the + battery terminal from the horn relay check that too. My '69 has a junction block on the radiator support near the battery. Also if you've added any high amp draw accessories, like a high power stereo with a power amp, your alternator might not be able to keep up with it at idle.

I cleaned the terminals of the horn relay and I unplugged the voltage regulator plug to try cleaning the terminals and I found a wire that was broken inside the insulation. It was the red battery wire. I replaced the wire and the light is out now.
