after getting stuck in the rain the other night my bikes battery wouldn't turn the starter over and the headlight was dim. It would kick over first try though and I was able to run around town for a while. is it possible that i ruined my regulator/rectifier since it's exposed? Or did my charging system finally croak? Just seems strange that I was able to do 20-30 miles with a dead battery and non working charging system? Not sure where to start checking?
