3.9 Battery Charger

The generator set is equipped with a 6-amp
float/equalize battery charger to maintain the engine
starting battery. The charger's DC leads are factory-
wired. Figure 3-7 illustrates the battery charger.
Periodically tighten all connections.
maintenance on the battery charger is required.

3.10 Circuit Protection

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

3.10.1 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 3-8 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.

3.10.2 Fuses

Three fuses are located next to the generator set
controller. The fuses are easily accessed from the
service side of the generator set. See Figure 1-1 for the
fuse location.
A 10-amp fuse in the battery charger DC lead protects
the battery charger. See Section 2.5.
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. See Figure 3-9 for fuse ratings and
part numbers.

3.11 Storage Procedure

Perform the following storage procedure before
removing the generator set from service for three
months or longer. Follow the engine manufacturer's
recommendations for storage, if available.
Note: Run the generator set monthly whenever
possible.

3.11.1 Lubricating System

1. Operate the generator set until it reaches operating
temperature, or about 15 minutes.
2. Stop the generator set.
3. While the engine is still warm, drain the engine
lubrication oil from the engine crankcase.
