when we got this car, the battery light was always on b/c one of the terminals was loose. we fixed that, and the light stayed on. we couldn't figure it out untill today when we noticed that our alternator was eating a hole in the side of the battery, which had apparently slid off the holder a little at some point. so now we have a ruined battery, and battery crap all over the alternator and everything else around it. do i need to clean this crap off and if so, how the heck do i do this? AAAUUUUGGGGHHHHHHHHHHHHHH shoot
