Okay, here's my situation. About 15 minutes ago I went to McD's to get some food for the family. As I aproached the drive thru, I slowly entered at sharp turn and something clicked in the engine bay, causing my orange "Anti-Lock" signal to come on. That mean't something was wrong/broken. I ordered my food and payed, then I pulled upto the last window. The AC was on full blast, the radio was off. As I took my food from the window, my speddometer crept upto 45 mph and the revs shot upto 3k, but the engine was idling, and this was in park. I engaged (D) and went foward 10 feet, then something clicked again and I didn't want to risk going out into traffic. So I parked and turned off the car. Then I tried to start it, it wouldn't start. The lights would dim but there was nothing from the engine bay. My car is a 96 Chevrolet Lumina sedan, and the alternator hasn't been doing well.
