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.

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
on the engine
of the vehicle with the dead battery.

9. Attach the cable at least 18 inches (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.
12. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don’t touch
each other or any other metal.
10. Now start the vehicle with the good battery and run
the engine for a while.
11. Try to start the vehicle with the dead battery.
If it won’t start after a few tries, it probably needs
service.
