I'm back from vacation.
I have confirmed the diodes on the rotor are good. I used a 12V light to test with the diode in series. The light lit up with the diode in one direction but not in the other direction. I soldered the diodes back in just as they were before removing.
I also tried to flash the exciter windings (I'm calling these the 2 wires going to the CAP) with a 12V battery and a 10amp fuse in series. I only held the battery on the lead for about 2 seconds. When I pulled the battery power off the exciter lead it sparked but did not blow the fuse.
Then I tried flashing the AC leads to the bridge rectifier for the 12V dc posts on the front panel. This flashing blew the 10 amp fuse. I then checked these leads for continuity and it was still reading Ok, about 1.2 ohms.
No change. Nada. Zilch.
I did the flashing with the generator not running.
I just wanted to touch base with any of you that might be following the thread.
