9. 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.
10. 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.
11. Now start the vehicle with the good battery and run
the engine for a while.
12. Try to start the vehicle with the dead battery.
If it won’t start after a few tries, it probably
needs service.
