The starter motor or shortly only starter is an essential component to start the vehicle. A starter delivers power to rotate the engine.

The car battery is also responsible for operating the starter. The battery also needs to supply enough energy to the starter motor, which is going to operate the engine.

But when you have a dead car battery, the starter does not deliver enough power to the engine to operate properly.

In several cases, I find for various technical issues; a starter motor can not start the engine while the battery supplies the power appropriately.

Grinding noise and starter cranks are the most common signs of a failing starter motor in a car.

To make the starter work again, you can whack the starter motor with a wrench or hammer that you have in your car.

You are going to find a starter motor on the driver’s side of your car between the transmission and your car engine.

8. Rubbing The Battery Terminal

By rubbing and tapping the battery terminal, you can help the battery to supply the power to the engine while the battery is not connected properly.

Also, rubbing around the battery terminal also helps the battery to supply electricity to electrical components in your car.

Avoid tapping the battery terminal too hard because a strong whack on the battery terminal can damage the battery.
