CAUTION
The engine “cranks” AND starts,
but runs only about 30-60
seconds and shuts down.
1. Make sure the correct grade
and amount of oil is in the
engine crankcase. See the
Maintenance Section of this
manual.
2. Make sure the engine is not
overheating.
3. Make sure the engine
alternator is operating properly.
1. The oil pressure switch may
be faulty. Perform the Oil
Pressure Switch Test.
2. The Temperature Switch may
be fault. Perform the
Temperature Switch Test.
3. The alternator may be faulty.
Perform the Alternator Test.
4. The Idler/Engine Protection
Board may be faulty
(PERKINS) The ECU

High idle speed should be
1800 RPM. If Necessary,
perform the Engine Throttle
Adjustment Test. (PERKINS
