2.4 Circuit Protection

If the generator set circuit breaker trips or the fuses blow
repeatedly, see Section 4, Troubleshooting, for possible
causes.
2.4.1

Line Circuit Breaker

A line circuit breaker interrupts the generator output in
the event of a fault in the wiring between the generator
and the load. The line circuit breaker location is shown
in Figure 1-1. See Figure 2-5 for the circuit breaker
ratings. If the circuit breaker trips, reduce the load and
switch the breaker back to the ON position. With the
breaker in the OFF position the generator set runs but
the generator output is disconnected from the load.

Fuses

The engine harness contains two 10-amp and one
20-amp inline fuses. See Figure 2-6. Another 10-amp
fuse protects the battery charger.
Always identify and correct the cause of a blown fuse
before restarting the generator set. Refer to Section 4,
Troubleshooting, for conditions that may indicate a
blown fuse. Replace blown fuses with identical
replacement parts.

2.5 Battery Charger
The generator set is equipped with a 6-amp
float/equalize battery charger to maintain the engine
starting battery. The charger's power cord must be
connected to a 120 VAC power source. Figure 2-7
illustrates the battery charger.
The battery charger uses an AGS 10 inline fuse. The
fuse is located in the battery lead. See Figure 2-7.
