The alternator in your vehicle is responsible for powering multiple electrical components. Here is how it functions and why it is an essential car part beneath the hood.
How an Alternator Works
An alternator essentially turns mechanical power from the serpentine belt into electricity. The drive belts turn the alternator's rotor which energizes interior magnets located inside the housing. Then, it transfers this energy to charge the car battery. Other car parts that receive power from the alternator are the windshield wipers power windows, headlights, radio, radio, and electric steering.
Like other engine parts beneath your hood, alternators can, and will see their share of use. Since they run constantly when your car is in motion, they tend to last between 7 and 10 years or between 100,000 and 150,000 miles.
Some of the common signs showing that your alternator is going bad are:
- Grinding or whining noises from beneath the hood
- Dead battery
- Trouble starting car
- Smell of burning rubber
- Battery warning lights on dashboard
- Dimming or shuttering lights
