Hello, Here is some good information on diagnosing a charge problem on a Camaro. It should be a good place to start: http://www.camaros.net/forums/showthread.php?t=82263 If that doesn't do the trick, I recommend downloading the manual for your car from http://www.autozone.com and following their repair guides. Best of luck! CarGrrl

Make sure all connections are solid, and the terminals to the battery are clean. You may have a large draw on the electrical system and after a few miles or minutes, what is appearing to short out or draw a large amount of current lets go. Have someone put a meter on the alternator to see if it is putting out a correct flow when your car meter is showing no output. It may be in your dash gauge.
