So the few times I've driven my car this summer, I seemed to have trouble with my Optima and it was only about 2 1/2 years old. Charged it, drove it, a week late dead. So I finally took it to Advanced Auto and they said it was "bad" and gave me a new one free because it was under warranty.
Well, last Monday I put the new Red Top in and hit the key just to be sure it was connected and closed the trunk. Went to start my car today and dead battery, which tells me it's not my battery, but something is draining it. I am short on electrical system diagnostics and don't have a clue where to start. Any suggestions about where to start looking, would be greatly appreciated. Thanks in advance.
