Circuit Breakers
If you need to check a circuit breaker that is on
the fuse panel, see Checking and replacing fuses in
this chapter to find out how to locate the fuse
panel.
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.
Diagnostic equipment is needed to check circuit
breakers. Refer to the manufacturer's
instructions.
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.
Since the circuit breaker for the headlamps is
mounted in the headlamp switch, you must
replace the entire switch to install a new circuit
breaker.
Fuse Links
Fuse links are circuit protectors that are part of
the wiring harness for some electrical equipment.
These, like fuses, open when the circuit lead
exceeds their amperage rating. Fuse links may be
purchased from your Ford or Lincoln-Mercury
dealer. See the following charts to find out
which electrical parts are protected by a fuse
link.
