I have a 68 GTO just replaced the alternator with a 1 wire alternator but before I did it the generator light on the dash stays on when the key is off like right when I hook up the battery.I disconnected the external voltage regulator of course not sure what the problem is could it possibly be a bad ground for the dash cluster maybe ? Any help would be much appreciated thank you

The GEN light requires power on both side of it to make it go off. As I recall, oe side is from the key, the other side is from the voltage regulator. Eliminating the regulator will cause the light to stay on. Since you seemed to have the light on prior to the swap, you may have had issues with the system to begin with.

You can read a lot more here on this link which should answer your questions and hopefully fix your issue:
