1.
Turn the start switch on the stalled engine to the
OFF position. Turn off all the engine's 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
fully recharge 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”.

After Starting Engine
Note:
In temperatures from 0 to 60°C (32 to 140°F),
the warm-up time is approximately three minutes. In
temperatures below 0°C (32°F), additional warm-up
time may be required.
When the engine idles during warm-up, observe the
following conditions:
• Check for any fluid or for any air leaks at idle rpm
and at one-half full rpm (no load on the engine)
before operating the engine under load. This is not
possible in some applications.
• Operate the engine at low idle until all systems
achieve operating temperatures. Check all gauges
during the warm-up period.
Note:
Gauge readings should be observed and the
data should be recorded frequently while the engine
is operating. Comparing the data over time will help to
determine normal readings for each gauge.
Comparing data over time will also help detect
abnormal operating developments. Significant
changes in the readings should be investigated.
