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 (+) and negative (-) will go to
negative
(-)
or a metal engine part. Don't connect (+) to (-) or you'll
get a short that would damage the battery and maybe other parts, too.
6. Connect the red positive
(+) cable to the positive (+)
terminal of the
vehicle with the dead battery. Use a remote positive (+)
terminal if the
vehicle has one.
Dead Battery (+)
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.
8. Now connect
the black negative
(-)
cable to the good battery's
negative
(-)
terminal.
Don't let the other end touch anything until the next step. The other end
of the negative cable doesn't go to the dead battery. It goes to a heavy
unpainted metal part of the vehicle with the dead battery.
