My bike just shut off the other day, no power to anything. The main fuse was blown. I replaced it, but still no power to anything. The battery is less than a year old. I read several posts here and assumed the rr was bad. I replaced it last year with newer mosfet one. I ordered another one and swapped it out and I still have no power. I checked the voltage on the battery and it was around 13.6. Interesting though, when I turn the key on, the voltage grips drops to .5 or .6. I took the battery to be tested and they said it needed to be charged over night, not enough cranking amps. I had the battery on the charger for at least 24 hours right after the bike died. Not sure what else to test. Can't find any shorts anywhere. I removed the battery and jumped the bike off with cables and it started right up. The battery is on the charger right now. Do you guys have any other ideas that might help? Thanks!

 

did you check the 10A ignition/start fuse in the fuse box?

 

Yeah, I've checked all fuses. I'm thinking the battery is screwed, all though it's holding a charge.

 

Take it to most any auto parts store or motorcycle shop and have the battery load tested.

 

You could also hook a volt meter to the battery and check the vdc then turn the key to the ignition on so the headlight can act as a load and check the voltage drop. You should still have over 12 volts if the battery isn't dying.
