Hey guys. I have a 99 NB 2.0L GLS. Two days ago I tried to start the engine, and heard a series of loud rapid clicks, but the engine didn't start. I wasn't sure what it was, but Security at my university decided it was probably my battery and gave me a jump. After starting the car ran just fine, lights, radio all worked. I figured i'd drained the battery by accident the night before so I went driving on the highway for about 30 minutes to recharge it. Afterwards, when I turned off the engine and tried to start it again, I heard the same clicks and it wouldn't start. It's finals week right now so I don't have time until next week to get it looked at. But I was wondering, is this a dead battery or a dead alternator? How do I tell the difference?
