sounds like the regulator is stuck. Ground the F terminal on the generator and see if it charges then. If it does, either replace the regulator or open it up and look for burned or sticking contacts.

If you can't fix it with a hammer, you've got an electrical problem.

Hank, I believe that is the next step. It wouldn't be the first bad rebuilt unit. Before you do that though, make sure your grounds are good.
Did you try the same test with the field terminal of the generator grounded?

Yes, ground the F terminal on the generator and start it up. Check the voltage at half throttle or higher. If it's charging, it will read 7 volts or higher. This will tell you whether the regulator circuit or the generator circuit is the problem. Once you know that, we can proceed.
