Power Distribution Center: Operation

All of the current from the generator cable connection goes to the battery through a 10 gauge fusible link that is secured with a nut to the positive battery terminal at the starter. The PDC houses up to ten six fuse cartridges, which replace all in-line fusible links. The PDC also houses up to twelve blade-type fuses, up to two full International Standards Organization (ISO) relays, and up to eight mini International Standards Organization (ISO) relays. Internal connection of all the PDC circuits is accomplished by an intricate network of hard wiring and bus bars. Refer to appropriate wiring diagrams for complete circuit diagrams.

The fusible link, fuses and relays are available for service replacement. The PDC unit cannot be repaired and is only serviced as a unit with the engine compartment wire harness. If the PDC is faulty or damaged, the engine compartment wire harness assembly must be replaced.
