Step-by-Step Guide

1. Position the VehiclesPark the working vehicle close to the vehicle with the dead battery, but not touching. Turn off both vehicles and set the parking brakes.
2. Park the working vehicle close to the vehicle with the dead battery, but not touching. Turn off both vehicles and set the parking brakes.
3. Open the HoodsOpen the hoods of both vehicles and locate the batteries. Identify the positive (+) and negative (-) terminals on each battery.
4. Open the hoods of both vehicles and locate the batteries. Identify the positive (+) and negative (-) terminals on each battery.
5. Attach the Jumper CablesRed Clamp to Dead Battery: Attach one red clamp to the positive (+) terminal of the dead battery.Red Clamp to Live Battery: Attach the other red clamp to the positive (+) terminal of the charged battery.Black Clamp to Live Battery: Attach one black clamp to the negative (-) terminal of the charged battery.Black Clamp to Ground: Attach the remaining black clamp to an unpainted metal surface on the engine block or frame of the vehicle with the dead battery. This acts as a ground.
6. Red Clamp to Dead Battery: Attach one red clamp to the positive (+) terminal of the dead battery.
7. Red Clamp to Live Battery: Attach the other red clamp to the positive (+) terminal of the charged battery.
8. Black Clamp to Live Battery: Attach one black clamp to the negative (-) terminal of the charged battery.
9. Black Clamp to Ground: Attach the remaining black clamp to an unpainted metal surface on the engine block or frame of the vehicle with the dead battery. This acts as a ground.
10. Start the Working VehicleStart the engine of the vehicle with the charged battery. Let it run for a few minutes to build up a charge in the dead battery.
11. Start the engine of the vehicle with the charged battery. Let it run for a few minutes to build up a charge in the dead battery.
12. Start the Dead VehicleAttempt to start the vehicle with the dead battery. If it doesn’t start immediately, wait a few more minutes and try again.

17. Red Clamp from Live Battery: Remove the red clamp from the positive (+) terminal of the charged battery.
18. Red Clamp from Dead Battery: Remove the red clamp from the positive (+) terminal of the previously dead battery.
19. Let the Engine RunKeep the engine running for at least 15-20 minutes to allow the alternator to recharge the battery. If possible, drive around to help the battery regain its charge.

Tips and Troubleshooting

• Check Connections: If the car doesn’t start, double-check the cable connections to ensure they are secure and correctly placed.
• Battery Health: If the battery repeatedly dies, it might be time for a replacement.
• Avoid Sparking: Never allow the clamps to touch each other or other metal surfaces while attached to the battery to avoid sparks and potential damage.
