Default Kubota GL7000 No Output

Good evening guys!

I managed to land a running Kubota GL7000 that looked like it was in great shape. Engine fires right up, runs great! However, there is no voltage output from the generator.

Here are the symptoms that I believe must be related...


Nothing shows on the voltage gauge.

12V charging circuit does not appear to be working, as battery voltage holds @12.5V while running.

Shutdown solenoid does not actuate when key is moved to shutdown position.

Any help would be greatly appreciated, You guys have come through for me in the past.

Update: Flashed the rotor by running a drill backwards, and am now getting a small amount of output. Thoughts?

This appears to be the manual:
https://www.absolutegenerators.com/m...ice_Manual.pdf
It devotes WAY more time to the engine than the gen end, but it would appear the prime suspects would be brush wear, failed AVR, or winding issues. I suppose a logical first step would be to do the resistance checks from the manual, then work from there.
