Coolant Temperature Sensor (CTS)
The coolant temperature sensor (CTS) is used to
monitor engine temperature for the high engine
temperature fault shutdown. See Figure 8-26 for the
coolant temperature sensor location. Power down the
generator set and allow the generator set to cool.
Disconnect the CTS and use an ohmmeter to measure
the resistance across the sensor. The sensor
resistance varies with temperature and should be within
the values shown in Figure 8-27. If the resistance is very
low (indicated a short circuit) or very h igh (indicating an
open circuit) replace the CTS.

High Exhaust Temperature (HET) Switch
In the event of a shutdown because of high exhaust
temperature, the ADC IId controller will display fault
code Exh. Temp High Shutdown. See Figure 8-28 for
the high exhaust temperature switch location. High
exhaust temperature of 215_ ±5_ F (102_ ±2.8_ C) will
cause the unit to shut down.

8.15 Fuses
Fuses are located on the side of the junction box. See
Figure 8-29. Always identify and correct the cause of a
blown fuse before restarting the generator set. Refer to
Section 6, Troubleshooting, for conditions that may
indicate a blown fuse. Replace blown fuses with
identical replacement parts.
D 10 -Amp (F1) fuse protects the auxiliary winding.
D 20 -Amp (F2) fuse protects the controller circuits, fuel
pump, and fuel shutoff solenoid.
D 5-Amp (F3) fuse protects the customer connections.
