Thanks, guys.

I did go through the wiring as much as I could. In particular, I confirmed that I had a good ground connection everywhere. I also gently “cleaned” the regulator points with 600 grit sandpaper.

It sounds like things are working as expected in broad terms. That is, charges for a few minutes, fluctuates a bit and then settles out about zero. But, that “fluctuates” part is clearly a bit much.

If I have an intermittent short somewhere, it seems like it must be internal to the generator. What started all of this was that the system had stopped charging at all. After some testing, everything pointed toward the generator. So, as mentioned in my earlier post, I pulled the generator out, took it apart and carefully cleaned everything. I didn’t see any obvious broken wires or nicks in insulation or wire coating, but that doesn’t mean there aren’t any.

When I get some time, I may pull the generator back out and take another look.
