What are the warning signs of a malfunctioning alternator?

CNC Auto Repair • Feb 28, 2024

Your vehicle's alternator plays a crucial role in keeping the battery charged and powering the electrical components. When it malfunctions, it can lead to issues that may leave you stranded. 

This makes it important to visit the shop when you first suspect an alternator problem is developing. At CNC Auto Repair, we provide expert alternator replacement and auto electric repair in the greater Gonzales, LA area. Here are five symptoms of alternator trouble.


Dimming or Flickering Lights

One of the most noticeable signs of alternator trouble is dimming or flickering lights on your dashboard or headlights. The alternator is responsible for providing power to the electrical systems, and when it fails, the lights may lose their brightness or flicker intermittently. 


Warning Light on the Dashboard

When alternator trouble emerges, the first sign may be an illuminated dashboard warning light, which commonly reads ALT or GEN or is in the shape of a little battery icon. Warning lights should always be brought to the mechanic’s attention before the underlying issue escalates.


Strange Noises

A faulty alternator may produce unusual noises, such as grinding, whining, or squealing. These noises often stem from worn-out bearings or a failing belt within the alternator assembly. If you hear any of these sounds coming from the engine compartment, it's best to have your vehicle inspected promptly.


Malfunctioning Electrical Accessories

The alternator supplies power to electrical accessories such as power seats, power windows, and the radio. If these accessories struggle to function like they should, it could be due to alternator trouble.


Dead Battery

While a dead battery can be attributed to various issues, a failing alternator is a common culprit. The alternator charges the battery while the engine is running, so if it's not functioning correctly, the battery may soon lose its charge.
