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, starting the engine from an external electrical source may be necessary.
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.Before using an external electrical source to start the engine, ensure that the main power switch is OFF. Turn all electrical accessories OFF before attaching the jump start cables to the engine being started.
Turn the start switch to OFF. Turn off all accessories.
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.
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 combustible gases that are produced by some batteries.
Start the engine.
Immediately after the stalled engine is started, disconnect the jump-start cables in reverse order. Note: Problems with the alternator or the battery charger, may necessitate a separate source of power to run the engine after starting.
