A healthy alternator is crucial to your car’s electrical system. When it starts to fail, everything from your headlights to your battery is at risk. Our team provides top-tier alternator service using advanced diagnostics and high-quality parts to keep your vehicle running strong.
What Does an Alternator Do?
The alternator is a vital part of your car’s charging system. While the battery provides power to start your car, the alternator keeps it running by generating electricity once the engine is on. It powers all electrical systems, including:
-
Headlights and taillights
-
Dashboard gauges and warning lights
-
Radio and infotainment system
-
Power windows and locks
-
Heating and air conditioning systems
The alternator also recharges the battery while you drive. If it starts to fail, your vehicle’s systems can malfunction, and the battery can drain quickly—even if it’s brand new.
Signs You Need Alternator Repair or Replacement
A failing alternator can cause a wide range of issues. If you notice any of the following symptoms, it’s time to schedule an alternator service:
-
Battery warning light is illuminated on your dashboard
-
Dim or flickering headlights, especially at night
-
Slow engine crank or trouble starting your car
-
Frequent battery replacements
-
Electrical accessories acting erratically
-
Grinding or whining noises from under the hood
-
Burning smell, possibly from overheating wires or belts
Ignoring these signs can result in complete electrical failure, leaving you stranded. Catching alternator issues early can prevent breakdowns and costly repairs.
