~ 5-1-18 ~ Rev. “C”
Tachometer
- This gauge indicates engine speed. The engine can be operated at high idle without damage, but the
engine should not be allowed to overspeed. The engine can overspeed by downshifting or by going downhill. An
overspeed can result in serious damage to the engine.
Ammeter
- This gauge indicates the amount of charge or discharge in the battery charging circuit. Operation of the
indicator should be to the right side of “0” (zero). The charging system should be checked for a malfunction if the
indicator is constantly to the left side of “0” (zero) or if the indicator shows an excessive charge during normal operation.
Correct any problems.
Service Hour Meter
- This gauge indicates the total number of clock hours that the engine has operated. Hours of
operation are logged in the ECM. A service tool is needed to retrieve the hours from the ECM. A Service Hour Meter
may be installed on the engine.
Fuel Pressure
- This gauge indicates fuel pressure to the electronic unit injectors from the fuel fi lter. The indicator
should indicate the “NORMAL” range. A decrease in fuel pressure usually indicates a plugged fuel fi lter.
Fuel Level
- This gauge indicates the level of fuel in the fuel tank. The fuel level gauge registers the fuel level only
when the ignition switch is in the ON position.

NOTE: The high idle rpm and the full load rpm are stamped on the Information Plate.
WARNING!!
If the Shutdown mode has been selected and the warning indicator activates, engine shutdown
may take as little as 20 seconds from the time the warning indicator is activated. Depending on the application,
special precautions should be taken to avoid personal injury. The engine can be restarted following shutdown for
emergency maneuvers, if necessary.
NOTICE: The Engine Monitoring System is not a guarantee against catastrophic failures. Programmed delays
and moderate schedules are designed to minimize false alarms and provide time for the operator to stop the
engine.
NOTICE: The coolant level sensor is an optional feature.
