So after stopping into my girlfriend's house for a few minutes (maybe 15) I get in my car and try to start it up. I notice that when I press the brake I lose all power in the car. So we grab some jumper cables and try to jump it. When connecting the cables to my car I get no spark (seemed kinda strange). So I let it sit for about 10 minutes and get back in, the motor won't even turn a full rotation. So I'm hoping this is a battery problem and I can just replace it. Does anyone have any ideas? I just recently got my Kenne Bell installed, but it's been fine for the past week and a half or so, so I don't think it's an alternator problem, but if anyone has any ideas it would be appreciated.
