WRENCH-TORQUE 3863348 - Caterpillar

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.
If the installation is not equipped with a backup battery system, then it may be necessary to start the engine from an external electrical source.Many batteries which are considered unusable are still rechargeable. After jump starting, the alternator may not be able to fully recharge batteries that are severely discharged. The batteries must be charged to the proper voltage with a battery charger. For information on testing and charging, refer to the Special Instruction, SEHS7633, "Battery Test Procedure".
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.When using an external electrical source to start the engine, turn the generator set control switch to the "OFF" position. Turn all electrical accessories OFF before attaching the jump start cables.Ensure that the main power switch is in the OFF position before attaching the jump start cables to the engine being started.
Turn off all auxiliary power and accessories of the engine. Otherwise, these components will operate when the power source is connected.Before attaching the jump start cables, ensure that the control switch for the generator set is in the "OFF" position.
Perform all of the procedures in this Operation and Maintenance Manual (Operation Section), "Before Starting Engine".
Connect the end of one jump start cable to the positive "+" terminal of the battery for the engine that is being started. Connect the other end to the positive "+" terminal of the power source.
Connect one end of the second jump start cable to the negative "−" terminal of the power source. Connect the other end to the negative "−" ground of the starting motor.
Manual starting of the engine depends on the control panel.
To start engines with the EMCP II+P, EMCP II+ or the EMCP II control panel, turn the engine control switch to the "MAN. START" position.
To start engines with the Switchgear Conversion control panel, turn the engine control switch to the "LOCAL" position. The engine will start according to the parameters that are programmed into the switchgear.
To start engines with the EMCP3 control panel, press the "RUN" button.
After the engine starts, disconnect the cable from the negative "−" ground of the starting motor. Disconnect the other end of the cable from the negative "−" terminal of the power source.
Disconnect the cable from the positive "+" terminal of the battery for the engine that was started. Disconnect the other end of the cable from the positive "+" terminal of the power source.
