Now, since this is only three months old, I found that funny. Fully charged and put back in the vehicle, drove it back there and the starter read ok as well. Now, many years ago, my ex'es car died while I was driving it and the alternator was the culprit. Every place I know of is closed on Sunday, but the guy at the parts store recommended that I may have a short somewhere and should get the car tested for that. Since I will be sitting at home with no car just waiting for Monday to roll around so I can get it towed somewhere, is there something I can do tomorrow that may put my mind at ease? I have never done anything electrically with the car, so I am a complete novice in this area. Can someone out there help explain this system to me and any possible causes? Anything would help at this point.

do you have charge guage or idiot lite? the diodes may be going out in alt.
