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 will
get a short that would damage the battery and
maybe other parts, too. And don’t connect
the negative (
−
) cable to the negative (
−
) terminal
on the dead battery because this can cause sparks.
6. Connect the red positive (+) cable to the positive (+)
terminal of the dead battery. Use a remote
positive (+) terminal if the vehicle has one.
