Starting with Jump Start Cables
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
Will Not Crank and Engine Cranks But Will Not Start"
for further information. Make any necessary repairs.
If the engine will not start only due to the condition of
the battery, either charge the battery, or start the
engine by using another battery with jump-start
cables. The condition of the battery can be
rechecked after the engine has been switched OFF.
NOTICE
Never attempt to start an engine from an external
power source such as electric welding equipment,
which has a voltage that is unsuitable for engine
starting and will damage the electrical system.
For 904D-E28T industrial engines, use a 12 VDC bat-
tery source to start the engine.
For 904D-E36TA industrial engines, ensure that a 12
VDC or 24 VDC battery source is used to start the
engine.

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 cable terminal of the discharged
battery. Connect the other positive end of the
jump-start cable to the positive cable terminal of
the electrical source.
3. Connect one negative end of the jump-start cable
to the negative cable 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 fully batteries that are severely discharged.
The batteries must be replaced or charged to the
proper 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".
