Thanks JMOR! I'm quite open to hard facts, educated speculation, or even wild guesses!
I put the resistor in series to the field connection and it served my purpose today, but it definitely does not belong there. With this configuration I get (as you noted) partial output that follows RPMs more than need - but I like 5 (+/- 5 depending on RPMs; of course "negative charge" with lights) better than 10 to 20 constant, or 0.
I noticed a couple other orange ones with the same VR and no resistor; I didn't get a chance to ask the owners how it performed, but I presume OK. With the original cutout, the field is just dead grounded. Perhaps my generator's internals are more fickle than my quick teardown and looksee indicated. Or maybe I got a messed up VR, or perhaps I just need to tinker with it a bit more (with the resistor, I set the VR contact "heavy" and pretty much letting the resistor keep it off max) to get it right.
Thanks for the feedback. Wish I could help you more. Your generator isn't a 3 brush, with the 3rd being adjustable is it?
