I had a complete power outage a while back although the battery was fine. I checked every connection on the bike, checked the fuses, tested the ignition switch with the multimeter, made sure the grounds were clean, and found nothing wrong with any of these things. Turned out a wire was getting pinched between the tank and the frame until it finally shorted out. The short also burned up a long length of wire that had to be replaced, so one gremlin led to another (it was replaced with heavier gauge wire; the factory stuff is pretty thin). You might want to take a look under there just in case.
I have looked and can't find the fuse that is under the seat in the wiring diagram and it has me curious.
I also checked every diagram in both the Snidal manual and the super factory manual at least five times and I couldn't find that fuse marked anywhere on any of the digrams. If you find it on one of the diagrams, let me know 'cause I never did.
I also asked here a couple of times what circuit it was protecting but no one had an answer for me, so I'm still not sure what it's for (although that fuse kept blowing when I turned on the ignition until my other problems were fixed).
I later upgraded to blade fuses, much sturdier than the self-destructo test tube vials (one of them literally fell apart in my hand when I removed it).
