Its' hot out here in Vegas first of all. Was out riding last night and noticed that my dash lights looked dim. Didn't think anything of it since it is very bright on the Strip. Then my bike just shut off. My Tach was stuck @ 2000 rpm with key off. I turned the key on and then off again and everything reset. But, it would not start. I had nothing on the ignition. Waited a little while and tried again, but still nothing. So I pop started it it and drove about 1/4 mile and it shut down again. It seems like the battery just died, but that seems unusual. I know the batteries don't last out here in this heat, but it seems strange that it died that fast. Threw my brothers battery in it and made it home Where should I start checking for the problem. Thanks ahead of time. 2000 Busa.
