- Turn Off Both Vehicles: Before connecting any cables, make sure both vehicles are turned off to prevent any electrical surges that could damage the batteries or electronics.
- Connect the Cables Properly: Attach the red positive cable to the positive terminal of the dead battery first, followed by the other end to the positive terminal of the working battery, then connect the black negative cable to the working battery’s negative terminal and the other end to an unpainted metal surface on the dead vehicle.
- Start the Working Vehicle: Start the vehicle with the good battery and let it run for a few minutes to charge the dead battery.
- Attempt to Start the Dead Vehicle: After a few minutes, try starting the vehicle with the dead battery; if it doesn’t start, wait a few more minutes before trying again.
- Disconnect the Cables in Reverse Order: Once the dead vehicle starts, carefully remove the cables in the reverse order of how they were connected, starting with the negative cable from the previously dead vehicle.
- Let the Revived Vehicle Run: Keep the revived vehicle running for at least 20 minutes to allow the alternator to fully charge the battery.
