I recently had my clocks out and everything went wrong, when it started it would cut out within 5 Min's, i fort this was the alternator as the battery light stayed on and thats a sign of a faulty alternator so i replaced it with a reconditioned one. I've tried junks leads and it wont even start now, its trying but it wont fire up. its not the battery as i've had it tested and its fine, can any1 help me as i would be very grateful or reccommend any1 who could fix this
