For the other end of the black jumper cable, you have two options:
– Directly attach it to the negative terminal (−) of the dead battery (least safe).
– Safer Method: Instead, connect it to a metal part of the car frame (ground) on the vehicle with the dead battery, away from the battery itself. This reduces the risk of explosion from flammable gases that may be emitted.
Step 4: Start the Vehicles
Once the cables are connected securely:
- Start the vehicle with the working battery. Allow it to run for a few minutes.
- After a few minutes, attempt to start the vehicle with the dead battery. If it doesn’t start immediately, wait a few more moments before trying again.
Step 5: Disconnecting the Cables
Once your vehicle has started:
- Disconnect the black cable from the metal frame or the negative terminal of the dead battery.
- Disconnect the black cable from the functioning battery.
- Now, remove the red cable from the functioning battery.
- Finally, remove the red cable from the dead battery.
Always remove in reverse order to prevent any accidental short circuits.
Step 6: Ensure Everything is Working
Check to ensure that all electrical systems (like headlights, radio, etc.) are functioning correctly. If your car does not start after several attempts, there may be an underlying issue that needs to be addressed.
When to Seek Professional Help
While connecting a car battery is often a straightforward task, there are situations where it’s best to consult a professional. If you notice:
1. Damage to the Battery
If the battery is cracked, leaking, or swollen, avoid connecting it and seek immediate professional help.
2. Electrical Issues
If your car starts but electrical systems are malfunctioning, this may indicate deeper issues within the vehicle’s electrical system.
