I started my 69 Camaro the other day and the GEN light stayed on. When I turned the lights on the gauge indicated discharge (I left the light hooked up when I put gauges in it, so yes it has both). I figured the alternator was going bad. The next day I started it and the light did not come on. I drove it the following day with no problem. Today I went out and it turned over four or five times before there was not enough juice. I put a charger on it and got it started the GEN light flickered and the gauge showed a discharge when I turned the lights on. After the car warmed up and the idle smoothed out the GEN light went off and when I turned the lights on there was no discharge on the gauge. I took the alternator off and had it tested and it showed to be working fine. Any ideas? Voltage regulator maybe? The battery is fairly new,as well.
