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.
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.
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.
13. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don't touch
each other or any other metal.
14. Be sure to reinstall the remote positive (+) jump
starting terminal plastic cap on your vehicle.
