Re: no power
Nope. The headlight is on its own circuit. Pull the headlight fuse and start the bike if it will just to see. This is the time of year when batteries can be suspect. They may look OK by putting a multimeter across them after a charge, but quickly drain-off that skin charge. Remember too that idling will not provide net positive charging. Batteries have been known to short-out. The brain box needs like 10.3 volts to provide spark.

Your main fuse for the models you are listing below your name will have a main fuse separate from the fuse box. It will be under your seat near the left side cover. 30 amp.

I think it might be time to clean all of the ground connections, but it is difficult for me to give advice on electrical while on line. It is something that I am only halfast good at if I am in person. Someone else chime-in here?
