I have a problem with my fox body. The problem was on my way home from work. My car drove all the way to work fine. No problems. I go to get in my car to leave. It will not start. I hear the clicking sound that means a bad battery. The battery is a week old. Optima 12v battery. my lights would still turn on and my radio would turn on but would not crank. I still just for the hell of it try to jump it. It takes a jump. On my way home, I am at a light, and it kills in the middle of driving it. From this, I would think that would rule out the battery, because if the alternator was good, you should be able to drive your car without the battery so I don't think it is battery. Next. Could the up's have slowed the accessories so much that I need a higher amp alternator? I took the alt to auto zone last week when I had problems, tested it 3 times and it came back good. I tried to tap the starter with a rubber hammer to try to see if it was the starter but it is not even getting past the clicking so I don't think it is the starter. The only 2 electric things I have on the car is a simple cd player and an electric fan. The fan does come on when the key is on the on position. The guy ran it to the ignition. so I pull to the side of the road. I had the cable's back on to try to jump it. Could the alt be going on so that it was not charing the battery back and caused the battery to get low. I know it tested good at auto zone but it might not be enough alt for the up's? any thought of what it could be?
