One problem... I got in my car this morning and the battery was dead. Not sure what drained it. No lights on or anything that I would tell.

Then once I jumped it my temp guage read -32 deg and it said I was out of gas when the tank was full. As I drove to work, both the temperature, and my gas guage went up. So by the time I got to work I had like 50 miles to empty and it was 40 degrees out.

Any ideas? Did I screw something up or did something just go out on the exact day that I finished my stereo project?
