What are the common symptoms of alternator failure?

Fuzion Autoworks • Sep 30, 2024

The alternator plays a crucial role in your vehicle by generating power for the electrical system and charging the battery. When it starts to fail, various problems can arise that affect your car’s performance and reliability. At Fuzion Autoworks, we provide expert European alternator replacement and auto electric repair in the greater Washington, UT area. Here are five common signs that your alternator is failing.


Warning Light on the Dashboard

Modern vehicles commonly have a dedicated warning light that activates when the alternator is malfunctioning. It may appear as a battery icon or an ALT or GEN symbol. If this light comes on, it’s a strong indication that the alternator is not performing as it should, and you should get your vehicle checked as soon as possible.


Dim/Flickering Lights

Oftentimes, one of the early indications of an alternator issue is dim or flickering headlights and interior lights. Since the alternator powers the electrical components, it’s a red flag if the lights dim or flicker. This could mean the alternator is struggling to provide enough power to keep everything running smoothly.


Weak or Dead Battery

While the alternator charges the battery, a failing alternator may not provide sufficient charge. As a result, your battery may die or seem weak, even if it’s relatively new. If you find yourself needing regular jump starts, it could be the alternator causing the issue, not the battery itself.


Malfunctioning Electrical Accessories

When an alternator is failing, it can cause various electrical issues in the vehicle. These can include problems with power windows, stereo systems, or other electrical accessories. If multiple electrical components start acting erratically, your alternator may not be supplying enough power.


Abnormal Noises

A failing alternator can produce unusual sounds such as grinding or whining. This could be due to a bearing or belt issue. If you hear strange noises from under the hood, it’s important to alert the mechanic.
