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 engine 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.
10. 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.
