Use a remote positive (+) terminal if the vehicle
has one.
7. Do not 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
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. The other end of the negative (−) cable does
not go to the dead battery. It goes to a heavy,
unpainted metal engine part, or to a remote
negative (−) terminal on the vehicle with the
dead battery.
6. Connect the red
positive (+) cable to the
positive (+) terminal
of the dead battery.
The electrical connection is just as good there, and
the chance of sparks getting back to the battery
is much less.
Your vehicle has a remote negative (−) terminal for
this purpose.
10. Now start the vehicle with the good battery and run
the engine for a while.
11. Try to start the vehicle that had the dead battery.
If it will not start after a few tries, it probably needs
service.
9. Connect the other end
of the negative (−)
cable at least 18 inches
(45 cm) away from the
dead battery, but not
near engine parts
that move.
