The fuse panel is located behind an access cover in
the left side of the cab arrangement. Remove the
cover in order to expose the fuses and relays.
Replace fuses with the same type and size only.
Otherwise, electrical damage can result.
If it is necessary to replace fuses frequently, an
electrical problem may exist. Contact your Caterpillar
dealer.
The fuses protect the electrical system from damage
that is caused by overloaded circuits. If the element
inside the fuse separates, replace the fuse. Check
the circuit if the element is separated in the new fuse.
Repair the circuit, if necessary.
Illustration 268 shows the location of the fuses. The
fuses are numbered from the top to the bottom.
A film with the positions of the fuses is located on the
inside of the access cover. The location of the fuse
matches the location of the pictograph on the film.

Relays
Note: Your machine may not utilize all of the relays that
are listed here. You should only replace these relays
with relays of the same type.
Indicators and Gauges - Test
Check for broken indicator lights, broken switches or
broken lenses on the instrument panel gauges.
Start the engine. Run the engine until the instrument
panel gauges have stabilized. Check that the
instrument panel gauges are operating correctly.
Stop the engine and perform any necessary repairs
before the machine is operated.
