Safety Precautions

• Be sure all electrical equipment is off. If you connect the jumper battery while a load is being drawn, a spark could occur.
• Check the battery-fluid level. If the plates are exposed, add water until they are covered. Never add acid.
• Make sure both batteries are of the same voltage.
• Make sure vent caps are in place to prevent electrolyte splash.
• Use good quality jumper cables.

Jump Starting

Before connecting the jumper cables, be certain of the battery polarity:

• Connect the first cable (red) to the positive (+) terminal of the good battery and then attach the other end of that (red) cable to the positive (+) terminal of the dead battery,
• Next, attach the second cable (black) to the negative (-) terminal of the good battery,
• Attach the fourth and final connector (black) to a clean metal part, such as the engine block of the vehicle being energized, rather than to its negative battery terminal*.
• Never lay your tools on top of the battery as they could come in contact with both posts, or the positive post and a ground, creating a short,
• Start the engine of the good vehicle and increase the engine to a fast idle for about one minute,
• Start the engine of the dead vehicle,
• Once started stop the engine of the good vehicle and turn off the ignition,
• Leave the engine of the jumped vehicle running, 
• Disconnect the jumper cables using the reverse procedure from above**.

*NOTE: This method completes the electrical circuit as if it were connected to the dead battery, however any sparks that are produced are kept away from explosive battery gases.

**CAUTION: DO NOT allow the exposed metal parts of the jumper leads to touch each other or other metal parts of either vehicle until all leads have been safely disconnected.
