IOD FUSE (Continued)
as various other accessories that require battery cur-
rent when the ignition switch is in the Off position,
including the clock. The only reason the IOD fuse is
disconnected is to reduce the normal IOD of the vehi-
cle electrical system during new vehicle transporta-
tion and pre-delivery storage to reduce battery
depletion, while still allowing vehicle operation so
that the vehicle can be loaded, unloaded and moved
as needed by both vehicle transportation company
and dealer personnel.
The IOD fuse is disconnected from PDC fuse cavity 18
when the vehicle is shipped from the assembly plant.
Dealer personnel must reconnect the IOD fuse when the
vehicle is being prepared for delivery in order to restore
full electrical system operation. Once the vehicle is pre-
pared for delivery, the IOD function of this fuse becomes
transparent and the fuse that has been assigned the
IOD designation becomes only another Fused B(+) cir-
cuit fuse. The IOD fuse serves no useful purpose to the
dealer technician in the service or diagnosis of any vehi-
cle system or condition, other than the same purpose as
that of any other standard circuit protection device.
The IOD fuse can be used by the vehicle owner as
a convenient means of reducing battery depletion
when a vehicle is to be stored for periods not to
exceed about thirty days. However, it must be
remembered that disconnecting the IOD fuse will not
eliminate IOD, but only reduce this normal condition.
If a vehicle will be stored for more than about thirty
days, the battery negative cable should be discon-
nected to eliminate normal IOD; and, the battery
should be tested and recharged at regular intervals
during the vehicle storage period to prevent the bat-
tery from becoming discharged or damaged. Refer to
Battery for the location of additional service infor-
mation covering the battery.

REMOVAL

NOTE: When removing or installing the IOD fuse, it
is important that the ignition switch be in the Off
position. Failure to place the ignition switch in the
Off position can cause the radio display to become
scrambled when the IOD fuse is installed. Remov-
ing and installing the IOD fuse again with the igni-
tion switch in the Off position will usually correct
the scrambled radio display condition.
(1) Turn the ignition switch to the Off position.
(2) Remove the cover from the Power Distribution
Center (PDC).
(3) Remove fuse 18 from the PDC.

INSTALLATION

(1) Insert fuse 18 into the Power Distribution Cen-
ter (PDC).
(2) Install the cover to the PDC.

DESCRIPTION

Fig. 7 Power Distribution Center (PDC) Location
1 - PDC
All of the electrical current distributed throughout
this vehicle is directed through the standard equip-
ment Power Distribution Center (PDC) (Fig. 7). The
molded plastic PDC housing is located in the left
front corner of the engine compartment, just behind
the air cleaner housing and the battery. The PDC
housing has a molded plastic cover. The PDC cover is
easily removed for service access and has a conve-
nient fuse and relay layout label affixed to the inside
surface of the cover to ensure proper component iden-
tification.
The PDC housing is secured to the left inner
fender well an indexing pin and one screw. All of the
PDC outputs are through the integral engine com-
partment wire harness.

OPERATION

All of the current from the generator cable connec-
tion 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 con-
nection of all the PDC circuits is accomplished by an
intricate network of hard wiring and bus bars. Refer
to Wiring Diagrams for complete circuit diagrams.
