CAUTION
The engine starts normally, but
shuts down after running for
several seconds.
The engine will not develop full
power.
The engine will not shut down
when the run/stop switch is
moved to the stop position.
The oil pressure may be low.
Check the oil level and add oil
as needed. If necessary, contact
the engine manufacturer, or a
qualified engine specialist to
determine the cause of the low
oil pressure condition, and make
any required adjustments or
repairs.
The engine alternator belt may
be loose or broken. Replace the
belt and/or adjust the belt
tension.
The engine may be overheated.
Contact the engine
manufacturer, or a qualified
engine specialist to determine
the cause of the overheat
condition, and make any
required adjustments or repairs.
Check that there is an adequate
supply of fresh clean fuel, and
that the fuel shut-off valve is fully
open.
Check the fuel and air filters,
replace if necessary.
The idle/engine protection PC
board, alternator, oil pressure
switch, or engine coolant
temperature switch may be
faulty. Perform the
Engine
Protection System Test
.
Perform the
Engine RPM
Adjustment Test
.
There may be internal problems
with the engine. Contact the
engine manufacturer or a
qualified engine repair
technician.
Check the voltage at the
primary fuel solenoid. If the
voltage drops to zero when the
switch is turned off, and the
engine continues to run, there is
likely a failure in the fuel
system. Contact the engine
manufacturer or a qualified
engine technician.
If the voltage remains at the
solenoid after the switch is
moved to the stop position, the
run/stop switch has most likely
failed.
