Jeep Wrangler: Jump Starting Procedure / Disconnecting The Jumper Cables

  1. Disconnect the negative (-) end of the jumper cable from the engine ground of the vehicle with the discharged battery.
  2. Disconnect the opposite end of the negative (-) jumper cable from the negative (-) post of the booster battery.
  3. Disconnect the positive (+) end of the jumper cable from the positive (+) post of the booster battery.
  4. Disconnect the opposite end of the positive (+) jumper cable from the remote positive (+) post of the discharged vehicle.
  5. Reinstall the protective cover over the remote positive (+) post of the discharged vehicle.

NOTE:

Accessories plugged into the vehicle power outlets draw power from the vehicle’s battery, even when not in use (i.e., cellular devices, etc.). Eventually, if plugged in long enough without engine operation, the vehicle’s battery will discharge sufficiently to degrade battery life and/or prevent the engine from starting.
