Does Revving the Engine Help When Jumping a Car?

The Short Answer

No, revving the engine does not help when jumping a car. In fact, it can actually make the situation worse.

How Jump Starting a Car Works

When you jump start a car, you are essentially using the battery of another car to provide power to your car’s starter motor. This allows the starter motor to turn over the engine, which then starts the combustion process and gets your car running.

Why Revving the Engine Doesn’t Help

When you rev the engine, you are essentially just increasing the speed at which the starter motor is turning over the engine. This does not provide any additional power to the starter motor, and it can actually make the situation worse by putting more strain on the starter motor and the battery.

What to Do Instead

If you are having trouble starting your car, the best thing to do is to turn off the engine and wait a few minutes. This will give the battery time to recharge. You can then try starting the car again without revving the engine.

If you are still having trouble starting your car, you may need to have the battery checked or replaced.

Additional Tips

Here are some additional tips for jump starting a car:

* Make sure that the jumper cables are connected properly. The positive terminal on the donor car’s battery should be connected to the positive terminal on your car’s battery, and the negative terminal on the donor car’s battery should be connected to a metal surface on your car, such as the engine block.
* Turn off the engine of the donor car and let it run for a few minutes before trying to start your car. This will give the donor car’s battery time to charge up.
* If your car does not start after a few tries, wait a few minutes and try again. Do not keep trying to start the car over and over again, as this could damage the starter motor.
