Section 5. Troubleshooting
5.1 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 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.
5.2 Fault Messages
The controller displays fault messages to aid in troubleshooting. Selected fault messages and recommended checks are listed
in the Resetting the Controller After a Fault Shutdown section.
Identify and correct the cause of the fault condition. Then reset the controller after a fault shutdown. See the Resetting the
Controller After a Fault Shutdown section.
5.3 Circuit Protection
If the generator set circuit breaker trips repeatedly, contact an authorized Kohler dealer for service.
5.3.1 Controller Internal Circuit Protection
The controller is equipped with internal circuit protection. A fault message, Accy PwrOver Warning or MainPwrOverL Shutdown,
is displayed if this internal protection is activated. Press OFF to reset. Contact an authorized Kohler dealer for service.
5.3.2 Line Circuit Breaker

the circuit breaker trips, reduce the load and switch the breaker back to the ON position.
