Section 6 Troubleshooting
6.1 Introduction
Corrective action and testing in many cases requires
knowledge of electrical systems and electronic circuits.
Have an authorized distributor/dealer or trained service
technician perform testing and service.
Refer to the Engine Service Manual, TP-6776 for engine
service information.
The first step in troubleshooting the generator set
controls is to verify that the controller is correctly
configured for the generator set. The Generator Set
Operation Manual explains how to check and change
the controller configuration.
If the troubleshooting procedures in this section identify
a bad part, refer to the parts catalog for replacement part
numbers.
6.2 Initial Checks
When troubleshooting, always check for simple
problems first. Check for the following common
problems before r eplacing parts:
D Loose connections or damaged wiring.
D Dead battery.
D Fault shutdown. Check for a fault code on the
ADC IId display. Section 7.10.1 describes the
warning and shutdown fault codes.
D Blown fuses. See Figure 6-1 for fuse identification.
Always check and replace the fuses before replacing
other components. See the operation manual or
parts catalog for fuse part numbers.

D Incorrect controller settings. Always check the
controller configuration settings before replacing the
controller. Section 7.13 explains how to check and
change the controller settings.
Some problems may be solved by updating the
controller’s application program. Check Tech Tools,
Software, for information on ADC IId application
program updates. See Section 7.13.2 for instructions to
check the version number of the controller’s application
program and for more information on updating the
application program.
6.3 Troubleshooting Chart
Use the following table(s) as a reference in
