1995 sunfire. My sister came out of work one day to find her battery dead, she jumped it drove it home then the next day went to go to school and it was dead again. Unfortunly she is up at college no so i have not been able to check oout the car myself but in order to keep the battery from dieing she has to dissconect the negative battery cable when she parks and reconnect it when she goes somewhere. Does anyone have any ideas on what could be causing this?...Sorry for such little info. but thats all I got.
