Does Revving the Engine Help When Jump Starting a Car?

Introduction

Jump starting a car is a common procedure that can be used to get a dead battery going again. The process involves connecting the dead battery to a good battery from another vehicle using jumper cables. Once the cables are connected, the good battery will provide the power needed to start the dead battery.

One question that often arises when jump starting a car is whether or not revving the engine of the good vehicle will help to get the dead battery started. In this article, we will explore this question and provide you with the answer.

Does Revving the Engine Help?

The answer to this question is a resounding no. In fact, revving the engine of the good vehicle can actually make it more difficult to start the dead battery.

There are two main reasons why revving the engine does not help when jump starting a car.

1. It can damage the good battery. When you rev the engine, you are increasing the voltage output of the alternator. This can put excessive strain on the good battery and lead to damage.
2. It can make it harder to start the dead battery. When you rev the engine, you are using up the power that is available to start the dead battery. This can make it more difficult for the dead battery to get enough power to start.

What Should You Do Instead?

If you need to jump start a car, the best thing to do is to simply connect the jumper cables and wait a few minutes. This will give the dead battery time to charge up. Once the battery has charged up, you can then try to start the car.

If the car does not start after a few tries, you may need to wait a little longer for the battery to charge up. You can also try connecting the jumper cables to the starter motor instead of the battery. This will give the starter motor more power and make it easier to start the car.

Conclusion

Revving the engine of the good vehicle does not help when jump starting a car. In fact, it can actually make it more difficult to start the dead battery. The best thing to do is to simply connect the jumper cables and wait a few minutes. This will give the dead battery time to charge up and make it easier to start the car.
