Circuit Breakers
Two manual reset circuit breakers are located on
the front body. Each has a button that pops out if
the circuit breaker trips. The 10 amp circuit break-
er protects the safety and ignition circuits. The 7
amp protects the indicator lamps and hourmeter.
Glow Plug Activation Light
The glow plug activation light indicates the glow
plugs are operating (preheating).
Battery/Charge Malfunction Light
The charge light indicates the electric system is not
being charged.
Oil Pressure Warning Light/Horn
The oil pressure warning light and horn signal
indicate that engine oil pressure is below the safe
operating level [below 7 PSI (48 kPa)]. This
light
(and warning horn)
will come on when the ignition
is turned
ON,
but should go off after the engine is
started. If the light fails to come on when the igni-
tion switch is turned
ON,
it could indicate a burned
out bulb, or the inline 7 amp circuit breaker could
also be tripped. If the light comes on during engine
operation, stop the engine immediately and correct
the source of the problem before further engine
operation.
IMPORTANT:
Continued operation of the engine
with an illuminated oil pressure warning light
MAY
cause severe engine damage (if a low oil pressure
condition exists).
Water Temperature Warning Light/Horn
The water temperature warning light and horn
signal indicate that engine coolant temperature is
above the safe operating limit and the
engine is
overheating.
If this light comes on, there may be
a problem with:
● Radiator cooling air flow (material packed into
radiator cooling fins, clogged air intake screen)
● Electric Radiator Fan not operating properly
● Low coolant quantity in cooling system
● Thermostat function
● Coolant pump
Stop the engine and correct the source of the
problem before further operation.
IMPORTANT:
Continued operation of the engine
with an illuminated water temperature warning light
MAY
result in severe engine damage.
