WHAT TO DO IF...
Fuse Inspection and Replacement
All the electrical circuits have fuses
to protect them from a short circuit or
overload. If something electrical on
your chassis stops working, the first
thing you should check for is a blown
fuse.
1. Turn OFF all lights and accessories
and remove the ignition key to
avoid damaging the electrical
system.
2. Determine from the chart on the
fuse panel which fuse controls that
component.
3. Remove that fuse and see if it is
blown.
1 Blown
If it is blown, replace it with a fuse of
the same rating.
If a fuse of the same rating is not
available, a fuse of a lower rating may
be temporarily substituted. You can
also use a fuse from a circuit you can
do temporarily without (for example an
accessory circuit or radio).
CAUTION
When replacing a failed circuit
breaker, always use an approved
circuit breaker with a current rat-
ing equal to or less than the circuit
breaker being replaced. Only use
the approved Type II modified re-
set circuit breakers.
NEVER use
a Type I (automatic reset) or Type
III (manual reset) circuit breaker. A
fuse with a current rating equal to or
less than the circuit breaker being
replaced can also be used.
