The fuse panel is located on the left side of the interior storage box. Remove the cover in order to access the fuses.

Fuses - Fuses protect the electrical system from damage that is caused by overloaded circuits. Change a fuse if the element separates. If the element of a new fuse separates, check the circuit and/or repair the circuit.


NOTICE

Always replace fuses with the same type and capacity fuse that was removed. Otherwise, electrical damage could result.



NOTICE

If it is necessary to replace fuses frequently, an electrical problem may exist.

Contact your Cat dealer.


To replace a fuse, use the puller that is stored in the fuse panel. One fuse of 5 Amps, three fuses of 10 Amps, two fuses of 15 Amps, two fuses of 20 Amps, two fuses of 25 Amps, and one fuse of 30 Amps are contained in the fuse panel as spare fuses.

The following list identifies the circuits that are protected by each fuse. The amperage for each fuse is included with each circuit.
