If the other problems are suspected, perform the
appropriate procedure to start the engine.
Problems with the Wiring Harness
Illustration 30
ECM Connector J2/P2
Locate the ECM. Check the connector (1) 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, check
for a diagnostic code and consult your Perkins
distributor.
Cold Weather Starting
Startability will be improved at temperatures below
10°C (50°F) from the use of a cylinder block coolant
heater or from other means that are used to heat the
crankcase oil. Some engine applications use a jacket
water heater to improve startability. Use of a jacket
water heater will help reduce white smoke and
misfire during start-up in cold weather.
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
g06450459
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".
Starting with Jump Start
Cables
(Do Not Use This Procedure in
Hazardous Locations that have
Explosive Atmospheres)
i04132731
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.
