Your vehicle relies on electric power to function, even though it runs on gasoline or diesel. The alternator is part of its charging system, which causes the vehicle to lose power and require towing when it fails. Here’s what you need to know about alternators, including signs of imminent trouble.

How It Works

Vehicles with internal combustion engines feature rotating alternators, devices that dispense alternating rather than direct electrical currents. The auto part turns mechanical energy into electrical energy, which powers the car battery and other electrical systems like the windows, windshield wipers, radio, cabin and dashboard lights, and exterior lights. The alternator also keeps the battery up to 12 volts to crank the motor and start the car.

Alternators can last up to 15 years without needing maintenance or repairs. While a vehicle with a dead alternator can operate briefly from leftover battery power, it eventually ceases working because the battery does not get recharged when the car runs.

How to Tell If It’s Dying

These low-maintenance auto parts provide several warning signs when they are wearing out, including illumination of the Battery and Check Engine dashboard lights. You may notice dim dashboard, cabin, and exterior lights, or windows that operate too slowly.

As the alternator’s power continues to fade, its spinning parts start to wear or break, resulting in whining or grinding noises. Also, if the belts working in conjunction with the alternator get hot because of improper rotation, you may smell burning rubber. A weak or dead battery is another telltale sign of a dying alternator. If your vehicle experiences any of these symptoms, make an appointment with your auto repair company to diagnose the issue and replace the part.
