g'day, just found this site looking for help on my road bike. I own a 91 model zxr250. I put the battery back and hooked the leads up to it, turned the key to ignition and hit the start button when something close to the battery made a zap, and all the electrics died. Now I charged the battery, and was told i can hook the battery charger up to the leads and see if the bike will kick over. Instead it makes sounds in the regulator/rectifier next to the battery vibrate. Does this mean its stuffed? I checked all the fuses and they are fine. Except when this thing just buzzes.
