My bike left me stranded at a 4 way stop. All power shut off. I thought maybe I hit the key, although that would be difficult to do. I turned the key off and back on and nothing. I got the bike home and replaced the battery and the bike started right up. It's done it again, this time in front of my garage. Everything shut off and would not turn back on, so I checked my batt. voltage, it was 13.5 v. I put it back in and nothing. put the battery on the charger to recondition and now bike starts again. I am hoping someone has experienced this before and has a solution or advice. Bike is charging up to 14.4v and then comes down some while running. Thanks for your help.
