need a little help.... my buddy has a 600 amp and a 500 amp in 2 different dcs carts. a week ago. i replaced, the complete gas pedal assembaly, cart ran after install. but, was slow and it seemed it needed to be reprogramed. his daughter was driving it. before, we could get to program it. she seid, it moved forward stopped and then studdered. i put, the program on the computer and it showed no amps coming out of the controller. in dis-belief my buddy told me to try the other cart. so, we pluged it in and went to the same page the cart was running fine. we made a couple small changes and the cart was running fine, then with out warning it shut down. now i have 2 carts that don't run. what the hell is going on........
