Does Revving Engine Help Jump Car?

Introduction

When your car battery dies, you may be tempted to try to jump-start it by yourself. One common misconception is that revving the engine of the donor car will help to jump-start the dead car. However, this is not actually the case.

Why Revving the Engine Doesn’t Help

When you rev the engine of the donor car, you are increasing the speed at which the alternator is spinning. This can cause the alternator to produce more electricity, but it does not actually increase the amount of current that is available to jump-start the dead car. In fact, revving the engine can actually make it more difficult to jump-start the dead car because it can cause the voltage to fluctuate, which can damage the electrical system of the dead car.

What to Do Instead

If you need to jump-start a dead car, the best thing to do is to follow these steps:

1. Park the donor car close to the dead car, but do not touch the cars together.
2. Connect the positive terminal of the donor car’s battery to the positive terminal of the dead car’s battery.
3. Connect the negative terminal of the donor car’s battery to the negative terminal of the dead car’s battery.
4. Start the donor car and let it run for a few minutes.
5. Try to start the dead car.
6. If the dead car does not start, wait a few more minutes and try again.

Conclusion

Revving the engine of the donor car will not help to jump-start a dead car. In fact, it can actually make it more difficult to jump-start the dead car. If you need to jump-start a dead car, the best thing to do is to follow the steps outlined above.
