7. Don’t let the other end
touch metal. Connect
it to the positive (+)
terminal of the
good battery.
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.
