Definitely learning a lot from this process, and hopefullly others who might have this problem (and stumble upon this thread) might also learn, and solve their charging issue as well. Thanks for helping that happen!
I was of the mindset as Save_old_iron and when I grounded the field coil, as that eliminated most (if not all) of the wiring harness. Therefore, an intermittent wiring fault would pretty much be limited to the wire leading from the generator to the (-) side of the battery or inside the generator.
I'll start with the ground cable and work my way inside.
As they say, film at eleven!
