Does Revving the Engine Help When Jumping a Car?

When your car battery is dead, you may be tempted to rev the engine of the car that is providing the jump start. However, this is not recommended. In fact, it can actually make it more difficult to jump-start your car.

Why Revving the Engine Doesn’t Help

When you rev the engine, you are increasing the alternator’s output. This can lead to a voltage spike, which can damage the electrical systems of both cars. Additionally, revving the engine can cause the battery to overheat, which can also damage it.

How to Properly Jump-Start a Car

To properly jump-start a car, follow these steps:

1. Park the two cars close together, but not touching.
2. Turn off the engines of both cars.
3. Connect the positive terminals of the two batteries with the red jumper cable.
4. Connect the negative terminal of the good battery to an unpainted metal surface on the engine block of the dead car.
5. Start the engine of the good car and let it run for a few minutes.
6. Start the engine of the dead car.
7. Once the dead car is running, disconnect the jumper cables in reverse order.

Tips for Jumping a Car

• Use jumper cables that are in good condition.
• Make sure the connections are tight.
• Don’t leave the jumper cables connected for more than 10 minutes.
• If you can’t get the car to start after several attempts, don’t keep trying. You may need to call a tow truck.

Conclusion

Revving the engine does not help when jumping a car. In fact, it can actually make it more difficult. By following the proper steps, you can safely and easily jump-start your car.
