Okay, I played hooky from work tonight so that I could run my battery down to Autozone and have them test it. It was completely discharged. They recharged it, ran a test and all came out good. When I hooked the battery back up, I'm getting lights and all. But there was a sizzling arc sound coming from the alternator, so I disconnected the battery. Looks like I will be replacing the alternator this weekend.
