5. Check that the jumper cables don’t 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.
Don’t connect positive (+) to negative (
−
) or you’ll
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.

positive (+) cable to
the positive (+) terminal
of the dead battery.
Use a remote
positive (+) terminal if
the vehicle has one.
7. Don’t 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.
