NOTE: 1. Control Motor Voltage is Measured at throttle controller 4 (+) and 5 (-) terminals.
2. Yellow LED indicates power status (ON, OFF).
3. To protect the control motor from overloads, the control motor automatically cuts off
supply voltage to the motor when there is a heavy load on the motor and the
possibility of motor damage or burn out exists.
4. After the malfunction is corrected, turn the starter switch from "OFF" to the "ON"
position and normal operation will resume.
