4. Check all battery terminals and remove any
excessive corrosion before you attach the
jumper cables.
5. Turn on the heater fan in both vehicles.
Turning on the fan helps protect the
electrical system from voltage surges. Turn
off all other switches and lights in both
vehicles to prevent possible damage to either
vehicle's electrical systems.
Connecting the jumper cables
1. Connect one end of the first jumper cable to
the positive (+) terminal of the discharged
battery. (You can connect either jumper cable
to the positive (+) terminal, as long as you
use the same cable for both positive
terminals.) Most jumper cables have a red
cable and a black cable. The red cable is
generally used for the positive terminals and
the black for the negative ones.
2. Connect the other end of the first cable to
the positive (+) terminal of the booster
battery.
3. Connect one end of the second cable to the
negative (-) terminal of the booster battery
— NOT to the discharged battery.
4. Connect the other end of the second cable to
a good metallic surface on the engine or
frame of the disabled vehicle.
Do not connect the end of the second
cable to the negative (-) terminal of the
battery to be jumped. A spark may cause
an explosion of the gases that surround
the battery.
