ACTER 48V AC GOLF CART MOTOR CONTROLLER REPAIR PROGRAMMING WORKAROUND FOR C-ZONE CT&T ELECTRIC CARTS
This fix will only work if the power transistors "FETS" are fried on your original controller. So all you need is to get another exact model controller, but use the fully working programmed circuit board from your old controller and transfer it to the new one. The reason is that the new one is not programmed for your specific cart, but the old one is.
