If the other problems are suspected, perform the
appropriate procedure to start the engine.
Problems with the Wiring Harness

ECM Connector J2/P2
Locate the ECM. Check the connector to ensure that
the connector is secure. Lightly pull each of the wires
in the chassis harness.
1.
Pull each wire with approximately 4.5 kg (10 lb) of
force. The wire should remain in the connector.
2.
If a wire is loose, push the wire back into the
connector. Pull the wire again to ensure that the
wire is secure.
3.
Start the engine. If the engine does not start,
consult the nearest Perkins dealer for assistance.

Note:
If the engine has not been run for several
weeks, fuel may have drained. Air may have moved
into the filter housing. Also, when fuel filters have
been changed, some air will be left in the filter
housing. Refer to the Operation and Maintenance
Manual, “Fuel System - Prime” (Maintenance
Section) for more information on priming the fuel
system.
Ether Injection System (If
Equipped)
The ether injection system is controlled by the ECM.
The ECM monitors the coolant temperature, intake
air temperature, ambient air temperature, and
barometric pressure to determine when ether
injection is needed. At sea level, ether will be used if
any of the temperatures fails to exceed 0° C (32° F).
This temperature is subject to an increase as
barometric pressure increases.
Personal injury or property damage can result
from alcohol or starting fluids.
Alcohol or starting fluids are highly flammable
and toxic and if improperly stored could result in
injury or property damage.
Follow the procedure in this Operation and
Maintenance Manual, “Starting the Engine”.

(Do

This
Procedure
in
Hazardous
Locations
that
have
Explosive
Atmospheres)
The connection of battery cables to a battery and
the disconnection of battery cables from a battery
may cause an explosion which may result in in-
jury or death. The connection and the disconnec-
tion of other electrical equipment may also cause
an explosion which may result in injury or death.
The procedures for the connection and the dis-
connection of battery cables and other electrical
equipment should only be performed in a nonex-
plosive atmosphere.
