Fuses, Fuse Links and Circuit
Breakers
*
[SV39650(B FM)12/91]
Fuses, circuit breakers and fuse links protect
your vehicle's electrical system from overloading.
If electrical parts in your vehicle are not
working, the system may have been overloaded
and blown a fuse or tripped a circuit breaker.
Before you replace or repair any electrical parts,
check the appropriate fuses or circuit breakers.
*
[SV39700( ALL)10/89]
The following charts tell you which fuses or
circuit breakers protect each electrical part of
your vehicle. If a fuse blows or a circuit breaker
opens a circuit, all the parts of your vehicle that
use that circuit will not work.
[SV39750( M)10/92]
Selected circuits, such as headlamps and
windshield wipers, are protected with circuit
breakers. A circuit breaker is designed to stop
current flow in case of a short-circuit or
overload. It will automatically restore current
flow after a few seconds, but will again interrupt
current if the overload or short-circuit continues.
This on-off cycle will continue as long as the
overload or short-circuit exists.
*
[SV39800( ALL)06/95]
Once you have determined which fuses or circuit
breakers to check, follow the procedures under
Checking and replacing fusesorChecking and
replacing circuit breakerslater in this chapter.

Power Distribution Box
*
[SV41400( ALL)10/92]
The high current fuses contained in the Power
Distribution Box protect your vehicle's main
electrical systems from overloads; these fuses
provide the connection between the battery and
your vehicle's electrical systems.
*
[SV41500( ALL)10/92]
The high current fuses are coded as follows: 30
amp -light green, 40 amp - orange, 50 amp - red,
60 amp -blue.
*
[SV41600( ALL)05/95]
RWARNING
Always disconnect the battery before
servicing high current fuses.
*
[SV41620( ALL)05/95]
Ford recommends that high current fuses be
replaced by a qualified technician.

RWARNING
Always replace the cover to the Power
Distribution Box before reconnecting the
battery or refilling fluid reservoirs.

[SV41800( ALL)04/95]
A blown high current fuse may be replaced but
will continue to blow until the cause of the
overload condition is corrected.
*
[SV41900( ALL)05/95]
RWARNING
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.

Checking and Replacing Fuses
*
[SV42300( ALL)02/95]
If you need to check a fuse, follow these steps:
[SV42600( M)10/92]
1. Remove the fuse panel cover by squeezing
together the cover release tabs as you apply
a slight pulling motion at the same time. The
underside of the cover contains five spare
fuses and a fuse pulling tool in case you
need to replace a blown fuse.
*
[SV43200( M)03/94]
The spare fuses for your vehicle are color coded
as follows: 10 amp Ð red, 15 amp Ð light blue,
20 amp Ð natural, 30 amp Ð light green.
*
[SV43300( ALL)06/95]
2. On the fuse panel cover, find the number of
the fuse you want to check. The diagram on
the cover tells you where to locate the fuse
on the panel.
*
[SV43350(B FM)10/92]
The underside of the cover also contains a
fuse pulling tool in case you need to replace
a blown fuse.

3. Check the fuse to see if it is blown. Look
through the clear side of the fuse to see if
the metal wire inside is separated. If it is,
the fuse is blown and should be replaced.

4. Replace the fuse with one that has the right
amperage rating (see previous chart).
*
[SV43700( ALL)05/95]
RWARNING
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.
*
[SV43800( ALL)06/95]
5. Put the fuse panel cover back on.
*
[SV44000( ALL)05/93]
Even after you replace a fuse, it will continue to
blow if you do not find what caused the
overload. If the fuse continues to blow, have
your electrical system checked.

Circuit Breakers
[SV44250( M)10/92]
If you need to check a circuit breaker that is on
the fuse panel, locate the circuit breaker
according to the instructions on the charts given
earlier in this chapter.
*
[SV44300( ALL)02/95]
Since you need diagnostic equipment to check
whether a circuit breaker works and such
equipment comes with instructions, we do not
discuss how to check circuit breakers.
*
[SV44400( ALL)10/92]
However, you should know that the circuit
breakers will reset themselves and allow the
electrical parts to work again once the overload
on the circuit is removed. If the circuit breakers
continue to cut off electricity, have your vehicle's
electrical system checked.
*
[SV44500( ALL)02/95]
If you replace a circuit breaker, use one with the
same amperage rating. To remove a circuit
breaker mounted in the fuse panel, grip it with
your finger and thumb and pull it straight out
of its socket.
