PM'd you with a link to a guide for a deep dive to test all the majority of your charging system components. If you want to "upgrade" to a series-based alternative, you may spend dearly on this: Compu-Fire 55402 . It's the smallest 3 phase "series" I've been able to source. You can find it for about $50 less on most retail sites. I have it on my girlie, shoe-horned into the stock position, but the leads are long enough to locate it elsewhere. As a series-type, it stays very cool, and I've not had an issue with running some substantial kit- extra lights, GPS, phone charger, heated grip and gear for fall tours.
