69 Chevelle Charging Issue

I have a 69 Chevelle and the alternator is not charging. Im getting 12.5 at the battery and 12.1 when the lights are on. I have the alternator with the 4 wires on the back with and external regulator. If I put my voltmeter on the lug marked BAT and the lug Marked GRD I get about 20.5-21.0 volts. I replaced the voltage regulator and also had the alternator tested. The test said the alternator was fine. I have a painless wiring system on my chevelle. Any help would be greatly appreciated. Thanks.

I just replaced the alternator and still having the same issue. I checked the grounds and everything looks good. Is there anyone in this forum that knows anything about this this system. The only reponse I have gotten is to change it over and I don't want to do that. Thanks.

Check the wires at the regulator could be a loose connection or a broken wire. Have you done a run down on all the wires yet? JMO
I have had this happen to me before also i changed the regulator and while doing so i found a connection bad and replaced the harness fron the fire wall out fixed my problem. JMO

Its like the regulator isn't giving the signal for the alternator to charge, Ill open up the harness cover tommorrow. It's all new painless wiring system so the wires should be fine. Should I trace all the regulator wires.

Have you replaced the voltage regulator??

There is a solid state version available that (I hear) is much more stable than
the OEM regulator

Something else to try would be to call painless and see if anybody else has had this problem. And all I said earlier was what I would do. you took it wrong. Haveing said that maybe there was a snafu that painless had with that harness and they may have a solution for you or can tell you were to look for a problem, they made it after all. Thats just my thinking.
