All controls and gauges are optional equipment for John
Deere OEM Engines. They may be provided by the
equipment manufacturer instead of John Deere. The
following information applies only to those controls and
gauges provided by John Deere.
IMPORTANT: Any time an electric gauge or meter
does not register correctly, replace it
with a new one. Do not attempt to repair
it.
Following is a brief description of the components on the
instrument (gauge) panel:
A—Oil Pressure Gauge - The oil pressure gauge
indicates engine oil pressure.
B—Coolant Temperature Gauge - The coolant
temperature gauge indicates coolant temperature.
C—Tachometer - The tachometer indicates engine speed
in hundreds of revolutions per minute (rpm).
The engine control system consists of the following:
D—Engine Control Light - The engine control light
illuminates after the engine has started and oil pressure is
up to specification. The light indicates that the engine
protection circuitry is activated.
E—Preheater Light - The preheater light illuminates
when the key is turned to the bulb test position (position
I). It should go off after approximately five seconds. When
the key switch is held in position II, the engine preheater
is energized and the preheater light illuminates.
F—Fuel Level Light - The fuel level light illuminates
when the key is turned to the bulb test position (position
I). It should go off after approximately five seconds. After
the engine is running, if the engine runs out of fuel, the
light will illuminate and protection circuitry will stop the
engine. The fuel level light will remain on indicating the
engine was stopped due to the fuel tank being empty.
