6. 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. And do not connect the
negative ( ) cable to the negative ( ) terminal on
the dead battery because this can cause sparks.

the positive (+) terminal of the good battery. Use a
remote positive (+) terminal if the vehicle has one.

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.
10. Connect the other end of the negative ( ) cable to
a heavy, unpainted metal engine part or to the
remote negative ( ) terminal, on the vehicle with
the dead battery.
11. Start the vehicle with the good battery and run the
engine for a while.
12. Try to start the vehicle that had the dead battery.
If it will not start after a few tries, it probably needs
service.
