Section 4 Controller Troubleshooting
4.1 Relay Controller
This section covers controller troubleshooting
procedures for 8.5/11RMY generator sets equipped
with relay controllers and related engine components.
Refer to the generator set Operation Manual for
operating instructions. Refer to Figure 4-2 or Figure 4-3
to identify the controller internal components. Some
controllers use a different circuit breaker than the one
shown in Figure 4-2. The integrated controllers shown
in Figure 4-3 have the cyclic crank circuits integrated
into the main circuit board and have a fault lamp on the
front face.
