Hi, Kell!
Those JC Whitney units are for alternators, not generators, so I doubt if they'd be useful in your situation. Is your Harley 6V or 12V? Also, does it have a conventional-type regulator with 3 units, or does it only have a cutout relay and a voltage regulator? Drop me an email, and we might be able to collaborate on something. My brother is an electrical engineer who designs solid-state stuff for the automotive industry.

Edit: I just noticed it's a 12V. That helps!
