8.
Now connect the black
9.
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.
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.
