Well put it like this my car was running fine and everything until i was on the highway and my speaker went out i thought the cd was scratched until i saw the battery light turn on then it started turning off i turned the car off then on everything seemed fine then i got home and the car wont turn on i put a battery on it and it turns on but then when i take it off it goes low and the car shuts off i have a bunch of wires hanging out i am in the process of taking them out if it isnt this is it the alternator???
