Gauge cluster and indicators
Diagnostic Lamp (1) - The diagnostic lamp is used to indicate the existence of a fault by flashing a fault code. For a more detailed discussion of the diagnostic lamp, please see this Operation and Maintenance Manual, "Diagnostic Lamp" topic.
Engine Oil Pressure (2) - The oil pressure should be greatest after a cold engine is started. The pressure will decrease as the engine warms up. The pressure will increase when the engine rpm is increased. The pressure will stabilize when the engine rpm is stable.A lower oil pressure is normal at low idle. If the load is stable and the gauge reading changes, perform the following procedure:
Remove the load.
Reduce engine speed to low idle.
Check and maintain the oil level.
Tachometer (3) - This gauge indicates engine speed (rpm). When the throttle control lever is moved to the full throttle position without load, the engine is running at high idle. The engine is running at the full load rpm when the throttle control lever is at the full throttle position with maximum rated load.
To help prevent engine damage, never exceed the high idle rpm. Overspeeding can result in serious damage to the engine. The engine can be operated at high idle without damage, but should never be allowed to exceed high idle rpm.
Note: The high idle rpm and the full load rpm are stamped on the Information Plate.
Coolant Temperature (4) - When the coolant temperature is above the normal operating value, the coolant temperature gauge will be in the red zone. Refer to the Messenger display for any additional information that may be available.
Warning Lamp (5) - There is a general fault in the engine. Refer to the Messenger display for any additional information that may be available.
Fuel Pressure (6) - This gauge indicates fuel pressure to the fuel injection pump from the fuel filter. A decrease in fuel pressure usually indicates a dirty fuel filter or a plugged fuel filter. As the fuel filter becomes plugged, there will be a noticeable reduction in the engine's performance.
System Voltage (7) - This gauge indicates the voltage of the electrical system.Circuit Breaker (8) - Reset the circuit breaker if a circuit breaker trips. Press the button in order to reset the circuit breaker. If the electrical system is working properly, the button will remain pressed. If the button does not remain pressed or if the circuit breaker trips soon after being reset, check the appropriate electrical circuit. Repair the electrical circuit, if necessary.Start Switch (9) - The start switch has three positions: OFF, RUN and START. When the start switch is turned clockwise to the RUN position, the lamps will flash for five seconds during the system test. The lamps will then
