Power Distribution Center: Operation

All of the PDC outputs are through the integral engine compartment wire harness, which exits from the front of the PDC housing.

All of the current from the battery/generator cable connection enters the PDC that is secured with nuts just inside the left end of the PDC housing. The PDC houses up to fourteen maxi-fuse cartridges, which replace all in-line fusible links. The PDC also houses up to six blade-type fuses, up to four full International Standards Organization (ISO) relays, and up to seven ISO micro-relays. Internal connection of all the PDC circuits is accomplished by an intricate network of hard wiring and bus bars. Refer to the appropriate wiring information . The wiring information includes wiring diagrams, proper wire and connector repair procedures, details of wire harness routing and retention, connector pin-out information and location views for the various wire harness connectors, splices and grounds.

The fusible link, fuse cartridges, 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.
