Alternator

📖 YOUCANIC Automotive Glossary

The alternator is an electrical generator that is powered by the engine of a car. It converts mechanical energy from the engine into electrical energy that is used to power the car’s electrical systems, including the headlights, radio, air conditioning, and other devices. The alternator also recharges the car’s battery, which provides power to the car when the engine is not running. The alternator has a built-in voltage regulator that maintains the proper voltage level for the car’s electrical systems. When the alternator is working properly, the voltage level should remain between 13.5 and 14.5 volts. A sign that the alternator may be failing is dimming or flickering lights, or electronics not functioning properly, such as radio, power windows or power locks. Other signs of a failing alternator could be warning lights on the dashboard, such as the battery warning light, or a dead battery, even if the battery is new. Also, a whining noise from the alternator could indicate a problem. It is important to have the alternator checked by a professional if you suspect that it is malfunctioning. A bad alternator can cause serious damage to the car’s electrical system if it is not addressed promptly. In summary, The alternator is an electrical generator that converts mechanical energy from the engine into electrical energy that is used to power the car’s electrical systems and recharges the car’s battery.
