1974 Caroche. Poor condition. My cart has a box mounted on the drivers side, under, near the motor with two cables that were connected to motor. It also has two wires handing down that are cut off. Is this a back up unit with beeper or ?. I removed all wires, bench tested and the motor spun. reconnected all wires and pushed pedal and got sparks. re bench tested motor and now it is welding. Any ideas from any one are welcome.
