TP-6517 1/11 37 Section 4 Scheduled Maintenance, 18 kW Models
Clean the battery and cables and tighten battery
terminals using the service schedule recommendations.
To prevent corrosion, maintain tight, dry electrical
connections at the battery terminals.
To remove
corrosion from battery terminals, disconnect the cables
from the battery and scrub the terminals with a wire
brush. Clean the battery and cables with a solution of
baking soda and water. After cleaning, flush the battery
and cables with clean water and wipe them with a dry,
lint-free cloth.
After reconnecting the battery cables, coat the battery
terminals with petroleum jelly, silicone grease, or other
nonconductive grease.
4.9 Battery Charger
The generator set is equipped with a 6-amp
float/equalize battery charger to maintain the engine
starting battery.
Figure 4-8 illustrates the battery
charger.
The charger’s DC leads are factory-wired. Periodically
tighten all connections.

4.10 Circuit Protection
If the generator set circuit breaker trips or the fuses blow
repeatedly, see Section 5, Troubleshooting, for possible
causes.
4.10.1 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 1-2. The circuit breaker rating is shown in
Figure 4-9. 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.

4.10.2 Fuses
Three panel-mounted fuses protect the alternator and
electrical controls. See Section 1.5 for fuse locations.
Another 10-amp fuse protects the battery charger. See
Figure 4-8 for the battery charger fuse location.
See Figure 4-10 for fuse part numbers. Always identify
and correct the cause of a blown fuse before restarting
the generator set. Refer to Section 5, Troubleshooting,
for conditions that may indicate a blown fuse. Replace
blown fuses with identical replacement parts.
