An optional line circuit breaker (sized for generator

output) is available to protect the generator from

damage because of overload or short circuits. If the

circuit breaker trips, reduce the load and switch the

breakers back to the ON position. With the breaker in

the OFF position, the generator set runs but there is no

output voltage.

NOTE

If the generator set circuit breaker trips repeatedly, see

Section 4. Troubleshooting for possible causes.

The controller circuitry is protected by a replaceable

10-amp fuse. Check the controller fuse if the generator

set will not crank and the battery and/or connections

appear correct. Replace fuse. If fuse blows again, see

Section 4. Troubleshooting for possible causes.

Voltage Regulator Fuse

A replaceable 10-amp fuse protects the voltage

regulator circuitry. The generator set shuts down if this

fuse is blown.

Typically with this condition, the

generator set starts and then shuts down in 8 seconds.

If this fuse is replaced and then blows again, see Section

4, Troubleshooting for possible causes. Location of the

voltage regulator fuse for 10-18 kW is shown in Figure

2-2. See Figure 2-7 for 6.5 kW.
