Battery Disconnect Switch
(If Equipped)
Allow at least 2 minutes after the engine has stopped
before you turn the battery disconnect switch to OFF.
Disconnecting the battery power too soon will prevent
purging of the Diesel Exhaust Fluid (DEF) lines after
the engine is shut down. Also, during the 2 minutes
the engine Electronic Control Module (ECM) is active
storing information from the engine and
aftertreatment sensors.
Not allowing the DEF purge to be performed can
damage the DEF system. Not allowing the engine
ECM time to store the information from the sensors
can damage to emission control system.
Some applications, the engine can be equipped with
a wait to disconnect lamp. The wait to disconnect
lamp will be illuminated during engine operation and
will be extinguished approximately 2 minutes after the
engine has stopped.

Gauges and Indicators

Your engine may not have the same gauges or all of
the gauges that are described. For more information
about the gauge package, see the OEM information.
Gauges provide indications of engine performance.
Ensure that the gauges are in good working order.
Determine the normal operating range by observing
the gauges over a period.
Noticeable changes in gauge readings indicate
potential gauge or engine problems. Problems may
also be indicated by gauge readings that change
even if the readings are within specifications.
Determine and correct the cause of any significant
change in the readings. Consult your Perkins dealer
or your Perkins distributor for assistance.
