Your car’s alternator plays a crucial role in keeping your vehicle running smoothly. It charges the battery and powers the electrical systems while the engine is running. When the alternator starts to fail, it can lead to serious issues that might leave you stranded. At Auto Check Complete Car Care, we provide expert alternator replacement and auto electric repair in the greater Katy, TX area. Here are five common signs of alternator trouble.

Dimming/Flickering Lights

One of the most obvious signs of a failing alternator is dim or flickering headlights or interior lights. The alternator provides the electrical current that powers these lights, so when it starts to wear out, it can no longer supply a consistent flow of energy. 

Battery Warning Light

Vehicles often have a dashboard warning light shaped like a battery, which can illuminate when there's a problem with the alternator. While this light is often mistaken as a battery issue, it’s commonly triggered when the alternator isn’t working correctly. If you see this light, it’s a good idea to get your vehicle checked out immediately.

Weak or Dead Battery

If your battery is consistently dying or can’t hold a charge, it might not be the battery’s fault—it could be your alternator. The alternator is responsible for keeping your battery charged, and if it’s failing, the battery will drain faster than usual, leaving your car unable to start. You can jump-start the car, but if the alternator is the issue, the battery will quickly lose power again.

Strange Noises

A failing alternator can cause unusual noises, often described as a whining or grinding sound. This could indicate a belt or bearing problem, and should be promptly brought to the mechanic’s attention.

Issues with Electrical Accessories

Since the alternator powers your vehicle’s electrical systems, problems with these systems can indicate alternator trouble. You may notice that your power windows, radio, or air conditioning are not functioning as they should. A weak alternator can also cause difficulty with accessories like heated seats.
