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.
IO.
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.
12.
Remove the cables in reverse order
to prevent electrical shorting. Take
care that they don't touch each
other or any other metal.
