Power Distribution (Vehicle S/N 11,438 to 99,999). The Power Distribution Panel

(PDP) is equipped with a Printed Circuit Board (PCB) used to control 12 VDC and 24 VDC

power throughout the vehicle.

1. The PCB is equipped with several LED's that illuminate to indicate the corresponding

circuits are functioning.

2. All electrical circuits are protected against overloads by circuit breakers.

3. From the PDP, wiring harnesses and cable assemblies carry electrical current to

operate vehicle equipment and accessories. Most electrical equipment and

accessories are grounded directly to the vehicle chassis.
