When you first turn over the key to start your car, it’s the battery that supplies the initial electrical charge. From the time your vehicle begins running, however, the alternator takes over as the generator and electrical power source. The alternator keeps all components, including the battery, charged while the car’s running, so there’s not such a huge pull on the system when it’s time to restart.
An alternator has a long life, and it is generally a maintenance-free part. Your system should alert you to initial signs that it’s about to go out. You can also be aware of what is occurring by knowing what to look for. One of the first symptoms is your lights are much dimmer than they had been previously. Another is the gauges on the instrument panel cease to work.
If you’ve noticed symptoms of a failing alternator, it may be time to have your vehicle serviced. Don’t hesitate to stop in to our auto service depot when you’re in Rockville, MD. Our knowledgeable service technicians are here to help.
