Ok, so here are today’s developments.
Replace the regulator. Fired up the generator. Undervoltage error.
Measured output near 0. No charge voltage to battery. 60.0 hz on display.
Flashed field
No change
Does anyone have actual resistance measurements for 11a-22a and 2-6?

Next test will be variable external dc supply for field coil to see if i actually can get output. If that works

Then we’ll attempt variable ac on exciter coil to see if the exciter coil is any good.

Any guidance, things to check, dc voltage measured while running on field, etc would be helpful

If you flash the field, do you get output on any of the windings?

During the flashing, output is way too high. Don’t remember the value, but >300v. Controller kills the engine immediately.
