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. |

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 Amperes, four fuses of 10 Amperes, three fuses of 15 Amperes, three fuses of 20 Amperes, two fuses of 25 Amperes, and one fuse of 30 Amperes 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.

(1) Main relay (80 Amp) (2) Alternator (100 Amp) | |
Main Breaker (1) - This fuse is to protect the electrical system. The circuit breaker has a capacity of 80 Amp.
Alternator Circuit (2) - This fuse is to protect the alternator. If the batteries are installed with reversed polarity, the circuit breaker would prevent the alternator from damaging the rectifier. The circuit breaker has a capacity of 100 Amp.
