I had the manual so I walked through the diagnostics and used an ohm meter on all of the windings.
The exciter winding was not within specs, and I assumed (incorrectly it turns out) that the exciter winding winding was bad AND that I had an electronic, non-brushless Generator.
I took off the bumper of the motorhome to get a better look at the generator.
After I took off the bumper I could see the front better and I noticed the small square plate on the front.
I removed the plate and found this.
Those look like brushes. So I removed the 2 leads and removed the 2 screws holding the suspected brushes to the commutator and removed the brushes and found a dirty commutator!!!
Not a great picture, but you get the idea, they look oxidized.
I got out some 600 grit sandpaper and WITH THE ENGINE OFF, very carefully started to remove the oxidation from the commutator. I also had to manually turn the engine by the flywheel to clean the entire commutator.
This is a picture in the commutator while I was cleaning it. It doesn't need to be perfect it just needs to generate enough power to excite the primary coils.
Now it works great!
