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.
