5. Check that the jumper cables do not have loose or
missing insulation. If they do, you could get a
shock. The vehicles could be damaged too.
Before you connect the cables, here are some
basic things you should know. Positive (+) will go to
positive (+) or to a remote positive terminal (+) if
the vehicle has one. Negative (
− ) will go to a heavy,
unpainted metal engine part or to a remote
negative (
−
) terminal, if the vehicle has one.
Do not connect positive (+) to negative ( − ) or you
will get a short that would damage the battery
and maybe other parts too.
{ CAUTION:
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engine is running.
6. Connect the red positive (+) cable to the positive (+)
terminal of the dead battery. Use a remote
positive (+) terminal if the vehicle has one.
7. Do not let the other end touch metal. Connect it to
the positive (+) terminal of the good battery. Use a
remote positive (+) terminal if the vehicle has one.
8. Now connect the black negative (
−
) cable to the
negative (
−
) terminal of the good battery. Use a
remote negative (
−
) terminal if the vehicle has one.
Do not let the other end touch anything until the
next step. The other end of the negative (
−
) cable
does not go to the dead battery. It goes to a
heavy, unpainted metal engine part or to a remote
negative (
− ) terminal on the vehicle with the dead
battery.
9. Connect the other end of the negative ( − ) cable at
least 12 inches (30 cm) away from the dead battery,
but not near engine parts that move. The electrical
connection is just as good there, and the chance
of sparks getting back to the battery is much less.
Use a remote negative (
−
) terminal if the vehicle has
one. Your vehicle’s remote negative (
−
) terminal
is marked GND.
