Use of Jump Start Cables
When auxiliary start receptacles are not available, use
the following procedure.
1. Make initial determination as to failure of machine
to crank. Refer to Special Instruction SEHS7768 on
use of 6V-2150 Starting/Charging Analyzer Group.
Procedure applies even if machine does not have
2. Place the propel control in the STOP position on the
stalled machine. Apply the parking brake. Move all
controls to HOLD.
3. On the installed machine, turn the engine start
switch to OFF. Turn off all accessories.
4. On the installed machine, turn on (close) the
disconnect switch (if equipped).
5. Move the energy source (machine) near enough to
the stalled machine for the jump start cables to
reach, but do not allow machines to touch.
6. Stop the engine on the electrical source machine.
Or, if using an auxiliary power source, turn off the
7. Make sure battery caps are all in place and tight on
both machines and that batteries in the stalled
machine are not frozen or low on electrolyte.
8. Connect positive (+) jump start cable (red) to
positive (+) cable terminal of discharged battery, or
battery set on stalled machine.
NOTE: Batteries in series may be located in separate
compartments. Use the terminal that is
connected to starter solenoid. This battery, or
battery set, is normally on the same side of the
machine as the starter.
Do not allow positive (+) cable clamps to touch
any metal other than battery terminals.
9. Connect the other end of this positive (+) jump start
cable (red) to the positive (+) terminal of the
electrical source. Use procedure of Step 8 to
determine correct terminal.
10. Connect one end of the negative (-) jump start
cable to the negative (-) terminal of the electrical
11. Make the final connection of the negative (-) cable
to the frame of the stalled machine (not battery
negative (-) post), away from battery, fuel or
hydraulic lines, and moving parts.
12. Start the engine on the electrical source. Or,
energize the charging system on the auxiliary
13. Wait a minimum of two minutes for the batteries in
the stalled machine to partially charge.
14. Attempt to start the stalled engine. Refer to section
on Engine Starting.
15. Immediately after starting the stalled engine,
disconnect the jump start cables in reverse order.
16. Conclude failure analysis on starting/charging
system of stalled machine, as required, now that
engine is running and charging system is in
