My gf's car died b.c she left her lights on. Her MORON boss tried to jump it but got the + - wrong. She said her car smoked and her horn went ape shit. I went to go pick her up after work and tried jumping it again. It seems her car battery has some juice left. It doesn't even click when you turn it on, no lights turn on.
Where do I start looking to diagnose the problem?
Thanks
