Dodge Durango (HB). Manual — part 750
POWER DISTRIBUTION CENTER
DESCRIPTION
All of the electrical current distributed throughout this
vehicle is directed through the Power Distribution Cen-
ter (PDC) (1). The molded plastic PDC housing is
located in the left front corner of the engine compart-
ment, just behind the battery. The PDC houses the
generator
cartridge
fuse
and
maxi-type
cartridge
fuses, which replace all in-line fusible links. The PDC
also houses blade-type fuses, relays, and a fuse
puller.
OPERATION
All of the current from the battery and the generator output enters the PDC through two cables with eyelets that are
secured with nuts to the two B(+) terminal studs located just inside the inboard end of the PDC housing. The PDC
cover is unlatched and removed to access the battery and generator output connection B(+) terminal studs, the
fuses, the relays, the joint connectors and the engine wire harness in-line connector.
REMOVAL
1. Disconnect and isolate the battery negative cable.
2. Depress retaining tabs on the side on the PDC (1).
3. Disconnect electrical harness connectors (2) and
remove PDC.
