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, it may be necessary to start the engine from an external electrical source.
For information on troubleshooting the charging system, refer to Special Instruction, REHS0354, "Charging System Troubleshooting".
Many batteries which are considered unusable are still rechargeable. After jump starting, the alternator may not be able to recharge batteries fully 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".
| NOTICE |
|---|
Use a battery that is sourced 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 the negative battery cable last and remove the negative battery cable first. When an external electrical source is used to start the engine, turn the control switch on the generator set 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 jump start cables are attached to the engine that is being started. |
- Engage the "STOP" button on the EMCP panel.
- 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 charging or starting source.
- Connect one negative end of the jump-start cable to the negative cable terminal of the charging or starting source. Connect the other negative end of the jump-start cable to the stalled engine block or to the chassis ground. This procedure helps to prevent potential sparks from igniting combustible gases that are produced by some batteries.
- Charge the batteries. The engine will not continue to run after starting if the batteries have not been charged.
- Start the engine.
- Immediately after the stalled engine is started, disconnect the jump-start cables in reverse order.
