I just charged (overcharged?) my battery, and it's back in the bike. With the key turned on, the lights all work normal, but when I try to start it, the battery starts smoking and giving a funky smell from the positive terminal. I dropped the battery taking it out, and think I may have cracked the case, but can't be sure. Even if it is cracked, where would that smoke be coming from? Where would it go if the case wasn't cracked? Also, the motor doesn't crank over but more than a couple of revolutions, real real slow before the solenoid just starts clicking and the smokeshow starts. Any thoughts would be greatly appreciated.
