The alternator plays a crucial role in keeping your vehicle's electrical systems running and ensuring the battery stays charged. When it begins to fail, it can cause a range of problems that affect your vehicle's performance and reliability. Recognizing the early signs of a failing alternator can help prevent sudden breakdowns. At ATL Total Car Care, our Murfreesboro mechanics provide expert alternator replacement and auto electric repair. Here are five common warning signs of alternator trouble.

Lights are Dimming/Flickering

A common symptom of a failing alternator is dimming or flickering lights, both inside and outside your vehicle. The alternator supplies power to your headlights, dashboard lights, and other electrical components. When it starts to fail, these systems may not receive consistent power, causing the lights to dim or flicker.

Dashboard Warning Light

Modern vehicles are equipped with a warning light on the dashboard, often shaped like a battery or labeled ALT or GEN. If this light comes on, it’s a warning sign that the alternator is not functioning properly. While the issue might also involve the battery, it’s smart to have the alternator inspected as soon as possible.

Strange Noises

A failing alternator can produce unusual noises, such as grinding or whining sounds. These noises are often caused by worn-out bearings or a belt problem. Ignoring these sounds can lead to more significant problems, including complete alternator failure.

Electrical Accessory Problems

The alternator powers the electrical systems in your vehicle, including power windows, radio, and air conditioning. If you notice these systems malfunctioning, such as windows rolling slowly or the radio cutting in and out, it could indicate that the alternator is struggling to provide sufficient power.

Dead/Weak Battery

While a dead battery can be caused by several factors, a failing alternator is often to blame. If your alternator isn’t charging the battery properly, the battery will drain quickly and may fail to start the engine.
