I'm having problems with my s-13 it wont stay running under its own power if you have it hooked up with jumper cables it runs fine and revs fine, But when you undo the jumper cables after a few minutes the car will die leading me to belive the alternator wasnt charging the batter i pull it off and it tests bad put a brand new one on and the car contiues to do the same thing any ideas would be greatly appreciated.
