so my car wouldn't start one day so i replaced the alternator and pulled the starter off it was still good. then alternator was shot so i figured it would be an easy fix. put everything back together and charged the battery. it wouldn't turn over so i jumped it thinking the obvious. i left it running for 30 mins. it runs fine, all the lights work stereo everything works, but as soon as i turn the car off it won't turn over, but i know the battery is getting a charge and the solenoid in the starter is clicking, so it is getting a feed also. is there anything else i could do?
