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.
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. 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 the remote negative (
−
)
terminal on the vehicle with the dead battery.
9. Connect the other end of the negative (
−
)
cable to the remote negative (
−
) terminal,
on the vehicle with the dead battery.
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.
