How to Use Jumper Cables?

JUMPER CABLE OPERATING INSTRUCTIONS

A.    CHECKING THE VEHICLE

CHECK THAT:

    1.  The two vehicles have the same battery voltage (6, 12 or 24 volts).
    2.  The two vehicles are not touching.
    3.  The ignition switches are off on both vehicles.
    4.  The gears are in neutral or park on both vehicles.
    5.  The hand brakes are set on both vehicles.

B.    ADDED PRECAUTIONS AND PREPARATIONS.

    1.  Be especially carful that the red clamps, on either end do not touch the black clamps.
    2.  Before connecting, spread the clamps on both ends wide apart.
    3.  Remember that Red symbolizes positive (+) and black symbolizes negative (-).
    4.  Be careful to avoid moving parts such as belts and fan blades.
    5.  Connection and disconnecting the booster cable to the batteries is extremely important.  You are not connecting the cable to the battery correctly if it causes a large spark.  Please carefully follow the steps in the exact sequence as outlined in the Section C.

C.  CONNECTING AND DISCONNECTING THE CABLE.

    1.  Connect one RED (+) clamp to the bad battery terminal post marked POSITIVE (+).
    2.  Connect the other RED (+) to the good battery post marked POSITIVE (+).
    3.  Connect the BLACK (-) clamp to the good battery marked NEGATIVE (-).
    4.  Connect the other BLACK (-) clamp to a ground (metal frame, or engine block) of the vehicle with the bad battery.
    5.  Turn on ignition of the vehicle with the bad battery and attemp to start the vehicle.  If the vehicle does not start immediately, start the vehicle with the good battery.  This will avoid excessive drain on the good battery.
    6.  After the engine of the vehicle with the bad battery is running normally, disconnect the clamps in the reverse order (steps 4, 3, 2 1 above)
