1939 6 volt, 3 brush generator, voltage regulator. The amp gauge is usually pegged over to the high charge side when running. Exception would be when I turn on the lights. Input from you folks would be helpful.

What's the voltage at the battery posts after running a while? If it's over 7.5, the voltage regulator points are stuck (the coil behind the Field wire) or there'a a grounded spot sonewhere in the field wire between the generator and regulator. It's also possible the battery just has a low state of charge and the generator is trying to recharge it. That would require driving for several hours without running the starter. Charge the battery overnight or longer and see if the problem goes away.

A 3 brush gen. does not use a voltage reg. 1939 models did not use a 3 brush gen. You may have a mismatch of parts there.

George, some Delco 3 brush setups used a 2-unit regulator- - - -cutout relay and voltage, no current regulator. I've got a Delco service manual from the early 1950's that covers that system and a bunch of others including the heavy duty 6-unit regulators used on the 24 volt military rigs.

I had never run into that. A guy is never too old to learn.

I would love to converse with you on some generator controller issues. I'm too new here to be able to PM you.
