10-82 Vehicle Care To disconnect the jumper cables from both vehicles, do the following: 1. Disconnect the black negative (−) cable from the vehicle that had the dead battery. 2. Disconnect the black negative (−) cable from the vehicle with the good battery. 3. Disconnect the red positive (+) cable from the vehicle with the good battery. 4. Disconnect the red positive (+) cable from the other vehicle. 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.
