The alternator plays a vital role in your vehicle by generating the electrical power needed to charge the battery and keep all electrical systems running smoothly. When the alternator begins to fail, it can cause various issues that impact your car’s performance and reliability. At Express Oil Change & Tire Engineers, we provide expert alternator replacement and auto electric repair in the greater Orlando area. Here are five warning signs of alternator trouble.

Dim or Flickering Lights

A common symptom of alternator trouble is dim or flickering headlights and interior lights. The alternator is responsible for powering these lights, and if it starts to fail, you may see inconsistent brightness. This issue is especially noticeable at night or when using multiple electrical accessories, as the alternator may struggle to supply sufficient power to all systems.

Battery Problems

While a dead battery can sometimes be the result of an aging battery itself, it is often a sign of alternator trouble. If the alternator is not charging the battery properly, the battery will deplete and may fail to hold a charge. 

Trouble with Electrical Accessories

A failing alternator can lead to erratic performance of your car’s electrical components. You may notice power windows and locks operating sluggishly, the radio cutting in and out, or the AC working poorly. These issues arise because the alternator is not delivering enough power to support all electrical functions simultaneously.

Warning Light Activation

If you see a battery-shaped light or one labeled ALT or GEN, it could mean your alternator is not functioning properly. While the light doesn’t specify the exact issue, it’s a clear indication that the charging system needs a professional inspection.

Unusual Sounds

Strange noises coming from under the hood can also signal alternator trouble. A grinding or whining sound might indicate worn-out bearings or a problem with the belt. These sounds often worsen and should prompt immediate attention, as they could lead to a complete alternator failure.
