8. Now connect the black
negative (
-
) cable to
the good battery’s
negative (

) cable. 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 part of the vehicle with the dead battery or to
a remote negative (
-
) terminal if the vehicle has one.
9. When connecting the
cable, be sure it is not
near any engine parts
that will move.
10. Now start the vehicle with the good battery and
run the engine for awhile.
11. Try to start the vehicle with the dead battery.
If it won’t start after a few tries, it probably
needs service.
