4.1 Introduction

Use the troubleshooting charts in this section to

diagnose and correct common problems. First check for

simple causes such as a dead engine starting battery,

loose connections, or an open circuit breaker. The

charts include a list of common problems, possible

causes of the problem, and recommended corrective

actions.

If the procedures in this manual do not explain how to

correct the problem, contact an authorized Kohler

distributor/dealer.

Maintain a record of repairs and

adjustments performed on the equipment. Use the

record to help describe the problem and repairs or

adjustments made to equipment.

4.2 Fault Codes

The Advanced Digital Control displays fault codes to aid

in troubleshooting.

Fault codes, descriptions, and

recommended checks are listed in Figure 2-4.

Identify and correct the cause of the fault condition.

Then reset the controller after a fault shutdown. See

Section 2.4.5.

4.3 Circuit Protection

If the generator set circuit breaker trips or the fuses blow

repeatedly, contact an authorized Kohler distributor/

dealer for service.

4.3.1

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. If the circuit breaker trips, reduce the load

and switch the breaker back to the ON position.

Fuses

Three 10-amp fuses are located on the junction box

near the circuit breaker panel. Four additional fuses are

located inside the junction box. See the service views in

Section 1 for the fuse locations and Figure 4-1 for

replacement fuse part numbers.

Always identify and correct the cause of a blown fuse

before restarting the generator set. Refer to Figure 4-2,

Troubleshooting Chart, for conditions that may indicate

a blown fuse. Obtain service from an authorized Kohler

distributor/dealer.
