10-78 Vehicle Care 9. Connect the other end of the negative (−) cable at least 45 cm (18 in) 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 will not start after a few tries, it probably needs service. Notice: If the jumper cables are connected or removed in the wrong order, electrical shorting may occur and damage the vehicle. The repairs would not be covered by the vehicle warranty. Always connect and remove the jumper cables in the correct order, making sure that the cables do not touch each other or other metal. Jumper Cable Removal A. Heavy, Unpainted Metal Engine Part or Remote Negative (−) Terminal B. Good Battery or Remote Positive (+) Terminal and Remote Negative (−) Terminals C. Dead Battery or Remote Positive (+) Terminal 6. Connect the red positive (+) cable to the positive (+) terminal location of the vehicle with the dead battery. Use a remote positive (+) terminal if the vehicle has one. 7. Do not let the other end touch metal. Connect it to the positive (+) terminal location of the vehicle with the good battery. Use a remote positive (+) terminal if the vehicle has one. 8. Now connect the black negative (−) cable to the negative (−) terminal location of the vehicle with the good battery. Use a remote negative (−) terminal if the vehicle has one. Do not let the other end touch anything until the next step. The other end of the negative (−) cable does not 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.
