My dumb*** turned the key a little too left and left the bike in park mode...couple of hours went by b4 my brother got home and mentioned to me that my back light was on...when i went to try to turn it on, the headlight was really dim and the starter button when flipped didnt make any noise, my question is if i can use one of those chargers that you mostly use to charge up car batteries. If so, what size is the battery so i can adjust the settings? My dad almost hooked up his car to it and i remember somebody telling me that was a bad idea so i didnt let him do it...i told him i was gonna ask some experts, you guys lol.........
