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.

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.

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 3-9 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 5, 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. The circuit breaker rating is 50 amps. 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

Two 10-amp and one 20-amp inline fuse are mounted

on the controller junction box. See Figure 3-10. Another

10-amp fuse is located in the battery charger lead.

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.
