Once the electrical connection has been established, you can begin dismantling the wiring. The dismantling process follows the reverse order of the installation. Begin by disconnecting the positive terminal from the powered car, then proceed to disconnect the positive terminal from the car without power. Next, remove the negative terminal from the powered car, and finally, disconnect the negative terminal from the car without a battery.
If the vehicle's battery is severely discharged, it may take a considerable amount of time for it to recharge properly after jump-starting. To ensure safety, it is generally recommended to drive normally for at least half an hour after starting the engine, as this allows the battery to sufficiently recharge. Additionally, it is advised not to idle the engine only, as the alternator's charging capacity is relatively low at idle speed, resulting in slow charging. If the battery continues to deplete despite these measures, it may be necessary to consider replacing the battery or inspecting the charging system for faults.
Here are the steps to jump-start a car:
Lift the protective cover or detector from the positive terminal of the discharged car's battery. Securely clamp one end of the red cable onto the positive terminal. Don't worry, as most car batteries operate at a safe 12V voltage.
This step is crucial: connect the other end of the red cable to the positive terminal of the charged car's battery. Be careful not to let the red cable's connector touch the negative terminal or any metal parts of the car's body to prevent short circuits and damage to the batteries.
Identify the black cable and locate the negative terminal of the discharged car's battery. Attach one end of the black cable to the negative terminal, ensuring a tight connection. Remember, there will be a surge of current when starting the engine, so exercise caution.
Connect the other end of the black cable to the negative terminal of the charged car's battery or a suitable metal part of the car's body or engine block. This is because the car's negative terminal is also connected to the body, known as grounding. Connecting the black cable after the red cable reduces the risk of short circuits if the red cable accidentally touches the car's body, preventing battery damage.
Start the charged vehicle and let it idle for a while, allowing the discharged car's battery to charge. Revving the engine at idle speed won't significantly help in charging the dead battery.
Ensure that all electrical devices in the discharged car are turned off, as they can drain power and require a higher starting current. Let the car start calmly. If the engine still doesn't start, slightly increase the idle speed of the charged car and try starting the discharged car again. Once the engine starts, allow both cars to idle for a while to recharge the discharged battery.
- Once the discharged car is running smoothly, you can disconnect the jumper cables. Follow the reverse order of the connection sequence: start by removing the positive terminal connection of the charged car, then the positive terminal connection of the discharged car. Next, remove the negative terminal connection of the charged car, and finally, disconnect the negative terminal of the discharged car without a battery.
