Cart was running fine, got back in and nothing after finishing hole. Selonoids click but no movement. Replaced contoller first of 2011 because of short burning it up. Checked all wires and no signs of shorted out wires and all connections look good on batteries. Could the controller have gone out without any warning. It was a rebuilt controller. Is there a way to test controller without removing it from cart. Any other ideas of what it could be ?
