Battery Disconnect Switch
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.
NOTICE
Never move the battery disconnect switch to the OFF
position while the engine is operating. Serious dam-
age to the electrical system could result.
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 of time.

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
for assistance.
In some engine applications are equipped with
Indicator Lamps. Indicator lamps can be used as a
diagnostic aid. There are two lamps. One lamp has
an orange lens and the other lamp has a red lens.
These indicator lamps can be used in two ways:
• The indicator lamps can be used to identify the
current operational status of the engine. The
indicator lamps can also indicate that the engine
has a fault. This system is automatically operated
via the ignition switch.
• The indicator lamps can be used to identify active
diagnostic codes.
Refer to the Troubleshooting Guide, "Indicator
Lamps" for further information.
NOTICE
If no oil pressure is indicated, STOP the engine. If
maximum coolant temperature is exceeded, STOP
the engine. Engine damage can result.
Engine Oil Pressure – The oil pressure
should be greatest after a cold engine is
started. The typical engine oil pressure
with SAE10W40 is 400 to 480 kPa (58 to 69 psi) at
rated rpm.
A lower oil pressure is normal at low idle. If the
engine speed and Load are stable and the gauge
reading changes, perform the following procedure:
1. Remove the load.
