Turn on cab switch, located in the cab next to the steering wheel. Location may vary by model and year of
truck. On trailer units, you will find a toggle switch near rear curb side corner post to activate the gate.
2. Check the circuit breaker at the main batteries:
Every truck has a circuit breaker on top of the main battery. Trailers and some trucks are equipped with an
auxiliary battery kit as shown in the pictures below (“Truck Battery” and “Auxiliary Battery”).

breaker or on battery box lid.
