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. 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. 9. Attach the cable at least 18 inches (45 cm) away from the dead battery, but not near engine parts that move. Theelectrical connection is just as good there, but the chance of sparks gettingback to the battery is much less. 12. Remove the cables in reverse order to prevent electrical shorting. Take care that they don't touch each other or anyother metal. 184
