I had my 2012 LS out for an friday night cruise, come Saturday the car was dead. head lights were off, when i jumped the car I tested the battery and the alternator and it was reading 14 amps. As soon as i shut off the car and went to restart it, all i got was starter noise. Is it that my battery is cooked? as the car only has 1000 miles. Or am i looking at something else?
