FUSES AND RELAYS
Fuses
If electrical components in the
vehicle are not working, a fuse may
have blown. Blown fuses are
identified by a broken wire within
the fuse. Check the appropriate
fuses before replacing any electrical
components.
Note:Always replace a fuse with one that has the specified amperage
rating. Using a fuse with a higher amperage rating can cause severe wire
damage and could start a fire.

Alternator - police
The high-output alternator provides 200 amperes of current to support
the high power requirements of modern police equipment. Output at idle
is approximately 130 amperes. Current demand by both the vehicle and
all energized police equipment in excess of this amount during vehicle
idling will place the electrical system into a discharge condition.
Electrical power management systems should be applied if necessary to
avoid discharging the battery.
Power distribution connector
Power for aftermarket equipment can be obtained from the power
distribution connector located under the glove compartment. This
connector contains several fused power feeds and inputs available for the
addition of accessories. The following tables show the circuits available
for equipment.

The mating connector is provided on the end of the power distribution
connector. The vehicle modifier can either purchase pins for the mating
connector and install them on the wires before they are inserted into the
connector, thereby avoiding any splicing, or purchase an optional power
pigtail for the interface. The power pigtail (P/N 14A411) plugs into the
power distribution connector and provides blunt cut wires ready for
splicing by the vehicle modifier.
See thePolice Interceptor Modifier Guidefor more details.
Rear power point - police
The rear power point is a battery access port for police auxiliary
equipment mounted in the trunk. It is capable of supplying 80 amps of
battery power. The front power distribution box (PDB) contains two
50 amp fuses, which protect the power point. Battery access is via two
studs contained in an enclosure, mounted in the trunk, on the right side
fender support. The terminal with the red wires is the battery positive,
and the terminal with the black wire is the ground. Remove both fuses in
the front PDB before removing the cover to the rear power point. Ensure
load devices can be turned off, and are switched off when reinserting
fuses.
WARNING:Under no circumstance should the rear power point
cover be removed without first pulling the two fuses in the front
power distribution box. Removing cover without pulling fuses could
result in an electrical hazard, and result in personal injury. Shut off
load devices before inserting fuses.
