8. Now connect the black
negative (
-) cable to the
negative (
-) terminal of
the good battery. Use a
remote negative (
-)
terminal if the vehicle
has one.
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 or to a remote negative (-) terminal
on the vehicle with the dead battery.
9. Connect the other
end of the negative (
-)
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, and
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 that had the dead battery.
If it won’t start after a few tries, it probably
needs service.
