At Johnny’s Muffler & Auto Express, we provide service on alternators, including repairs and replacement.
Alternators are crucial components in vehicles, as they convert mechanical energy to electrical energy. The name comes from the form of energy converted, which is an alternating current. Although many vehicle owners believe that the electrical components in their cars are powered by the battery, that isn’t necessarily accurate. The battery mainly provides power to electrical components when the engine isn’t running and to start the vehicle, but the alternator produces most of the electricity used by the audio system, headlights, windshield wipers, and other electrical systems and parts. Alternators also play a major role in the charging system of a vehicle.
If your car won’t start, you might immediately suspect that the battery is to blame. But a malfunctioning alternator can also create issues with starting a vehicle, so it’s important to check this component before replacing the battery. Nearly all vehicles that contain an internal combustion engine have alternators, and they’re often mounted to the front of the engine. An alternator includes several key components, which are the stator and rotor, voltage regulator, cooling fan, and diode rectifier. Each of these parts works together to convert mechanical energy to electrical energy, keeping your car’s systems running smoothly.
