Vehicle Care Connect it to the positive (+) terminal of the good battery. Use a remote positive (+) terminal if the vehicle has one. 7. Now connect the black negative (−) cable to the negative (−) terminal of 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. On your van, use the unpainted radio antenna bracket as a remote negative (−) terminal. 10-91 Notice: Your vehicle uses the unpainted radio antenna bracket as a remote negative (−) terminal. Move the antenna coax cable out of the way before clamping the negative jumper cable to the fixed antenna bracket. Avoid touching the negative cable clamp to the air conditioning line. Failure to do either of these could damage your vehicle. The repairs would not be covered by the warranty. 8. Connect the other end of the negative (−) cable to the negative (−) terminal location on the vehicle with the dead battery. On your van, use the unpainted radio antenna bracket as a remote negative (−) terminal. 9. Now start the vehicle with the good battery and run the engine for a while. 10. Try to start the vehicle that had the dead battery. If it will not start after a few tries, it probably needs service.
