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 positive (+)
to negative (-) or you'll get a short that would
damage the battery and may be other parts too.
6. Connect the red positive (+) cable to the positive
(+) terminal of the vehicle with the dead battery.
7. Don't let the other end touch metal. Connect it to
the positive (+) terminal of the good battery.
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 on the engine of the vehicle
with the dead battery.
9. Attach the cable at least 45 cm away from the
dead battery, but not near engine parts that move.
The electrical connection is just as good there, but
the chance of sparks getting back to the battery is
much less.
10. Now start the vehicle with the good battery and
run the engine for a while.
