I own a 1984 Club Car 36V cart in Florida that I loaned to a friend when I head north for the summer. Got a call that it was "bucking and jerking" during acceleration but went ok at top speed. Told her to park it and I would investigate in the fall. As I am told her friend checked voltages, connections and solonoids and didn't identify a problems. Some time later (shortly) I'm told the cart "took off" moving with the key off and no passanger in it. $500 damage to the cart and more to the home it hit (no personal injury) Is that possible, to move with the key off? Someone shifted it to neutral and unhooked the battery cables after that. Doesn't make sense to me and I'm 1700 miles away. Any ideas?
