Your vehicle's alternator is essential for keeping the electrical system running smoothly. It powers components like the headlights, dashboard lights, and battery. When the alternator begins to fail, it can lead to a range of electrical issues, potentially leaving you stranded if not addressed promptly. At Absolut Autoworks, we provide expert alternator replacement and auto electric repair in the greater Sterling, VA area. Here are five common signs of alternator trouble that you shouldn’t ignore.

Dimming or Flickering Lights

Since the alternator provides power to your vehicle's electrical systems, a failing alternator can lead to inconsistent electricity flow. You may notice that your headlights, dashboard lights, or interior lights become dimmer. If your lights flicker or appear weaker than usual, it’s a strong indication that your alternator may be struggling to provide enough power.

Dead or Weak Battery

While your battery stores electrical energy to start the engine, the alternator is responsible for keeping it charged while you drive. If your alternator isn’t functioning properly, your battery won’t receive enough power to stay charged, leading to a dead or weak battery. 

Strange Noises

Odd noises coming from your engine could also point to alternator trouble. A failing alternator often produces a grinding or squealing noise due to worn-out bearings or misalignment of the belt. If you hear unusual sounds under the hood, it’s important to promptly alert the mechanic.

Warning Light on the Dashboard

Most modern vehicles are equipped with dashboard warning lights that indicate alternator trouble. This warning light often looks like a battery symbol or says ALT or GEN. When this light comes on, it means the vehicle’s electrical system is detecting a problem with the charging system, which includes the alternator. 

Electrical Accessory Malfunctions

If your alternator is on its way out, you may notice other electrical malfunctions throughout the vehicle. These can include power windows that operate slowly or issues with the car’s infotainment system. If multiple electrical systems start acting up, there’s a good chance it’s due to an alternator problem that’s reducing the overall power available.
