Your vehicle’s alternator plays a crucial role in keeping the electrical system functioning properly. It generates the electricity needed to power systems like the headlights, radio, and power windows, while also keeping the battery charged. When the alternator begins to fail, your car may exhibit a range of symptoms that signal it’s time for replacement. Ignoring these warning signs could leave you stranded. At HESCO Automotive & Performance Center, we provide alternator replacement in the greater Birmingham, AL area. Here are four common signs that your alternator may be failing.

Battery Warning Light
The battery warning light on your dashboard doesn’t always mean there’s a problem with the battery itself. Often, it’s an early indication of an alternator issue. This light may come on if the alternator isn’t producing enough voltage. Some vehicles also have a specific alternator warning light, which should be taken seriously and investigated as soon as possible.

Dim/Flickering Lights
If your headlights or dashboard lights start to flicker or appear dimmer than usual, it may be due to the alternator not supplying enough power. As the alternator deteriorates, it can’t maintain a steady electrical output, which often results in erratic lighting performance.

Electrical Accessory Issues
If you start noticing multiple electrical issues, such as malfunctioning power windows or a failing radio, the alternator could be the culprit. Since the alternator supplies power to the electrical components, a decline in its performance can cause these systems to act up or stop working altogether.

Strange Noises
A failing alternator can produce a variety of unusual sounds. You might hear a grinding or whining noise coming from the engine bay. This often occurs when the alternator’s bearings are worn out or there’s a belt issue. These noises are not just annoying—they’re an important sign that something mechanical inside the alternator is breaking down.
