Hey guys, I'm back and I need some help with my little project BMW. Its a 1983 533i 5spd. I have had the alternator rebuilt and I have a new battery. I have cleaned the terminals on the battery and I am sure I have a good connection. I turn it over and it turns really slow usually, not fast enough to start it and I have to have it jumped. When I jump it, it starts right up and turns over really fast as it should. Although sometimes I go to it and expect it to turn over really slow and it turns fast and starts fine. What gives?
