Here's why:
* The alternator is the primary source of power for your car while the engine is running. It generates electricity to power all the electrical components in your car, including the headlights, radio, and most importantly, the ignition system.
* The alternator also charges the battery. When the engine is running, the alternator constantly recharges the battery, ensuring it has enough power to start the engine again.
* Without an alternator, your battery will quickly drain. Even if you charge the battery fully before starting the engine, it will be depleted by the car's electrical systems within a short period of time.
In short, the alternator is a vital component for any gasoline-powered car. Without it, your car will not be able to run for extended periods.
