3. Start the engine. If the engine does not start, check
for a diagnostic code and consult your Perkins
distributor.
Starting with Jump Start
Cables
(Do Not Use 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.
Improper jump start cable connections can cause
an explosion resulting in personal injury.
Prevent sparks near the batteries. Sparks could
cause vapors to explode. Do not allow jump start
cable ends to contact each other or the engine.
Note: If possible, first diagnose the reason for the
starting failure. Refer to Troubleshooting, "Engine
Does Not Crank and Engine Cranks But Does Not
Start" for further information. Make any necessary
repairs.
If the engine will not start only due to the condition of
the battery, perform one of the following procedures:
• Charge the battery
• Start the engine using another battery with jump-
start cables
The condition of the battery can be rechecked after
the engine has been switched OFF.
Using a battery source with the same voltage as the
electric starting motor. Use ONLY equal voltage for
jump starting. The use of higher voltage will damage
the electrical system.

Do not reverse the battery cables. The alternator can
be damaged. Attach ground cable last and remove
first.
Turn all electrical accessories OFF before attaching
the jump start cables.
Ensure that the main power switch is in the OFF posi-
tion before attaching the jump start cables to the en-
gine being started.
1. Turn the start switch on the stalled engine to the
OFF position. Turn off all the engines accessories.
2. Connect one positive end of the jump-start cable to
the positive terminal of the discharged battery.
Connect the other positive end of the jump-start
cable to the positive terminal of the electrical
source.
3. Connect one negative end of the jump-start cable
to the negative terminal of the electrical source.
Connect the other negative end of the jump-start
cable to the engine block or to the chassis ground.
This procedure helps to prevent potential sparks
from igniting the combustible gases that are
produced by some batteries.
Note: The engine ECM must be powered before the
starting motor is operated or damage can occur.
4. Start the engine in the normal operating
procedure. Refer to this Operation and
Maintenance Manual, "Starting the Engine".
5. Immediately after the engine is started, disconnect
the jump-start cables in reverse order.
After jump starting, the alternator may not be able to
recharge batteries to full capacity that are severely
discharged. The batteries must be replaced or
charged to the correct voltage with a battery charger
after the engine is stopped. Many batteries which are
considered unusable are still rechargeable. Refer to
Operation and Maintenance Manual, "Battery -
Replace" and Testing and Adjusting Manual, "Battery
- Test".
