7. Do not let the other end
touch metal. Connect it
to the positive (+)
terminal location of the
vehicle with the good
battery. Use a remote
positive (+) terminal if
the vehicle has one.
8. Now connect the black
negative (
−
) cable to
the negative (
−
)
terminal location of
the vehicle with the
good battery. Use a
remote negative (

)
terminal if the vehicle
has one.
Do not let the other end of the cable 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.
9. Connect the other end
of the negative (
−
) cable
to the negative (
−
)
terminal location on the
vehicle with the dead
battery. Your vehicle
has a remote
negative (

) terminal
marked GND (

).
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
will not start after a few tries, it probably needs
service.
