I have replaced basically everything but the batteries, which check ouy OK, and the motor. Sometimes the cart won't move at all, sometimes it moves at a crawl, and sometimes it works fine. The solenoid clicks everytime the accellerator is activated and the batteries show voltage. It has a new solenoid and relay, and the controller is fairly new as well. Maybe it's time for a new(good Used) motor. :headbang2:
