5 Signs of a Malfunctioning Alternator

Yanis Foreign Auto Repair • 20 May 2024

Your car's alternator plays a crucial role in keeping the battery charged and the electrical systems running smoothly. When you first notice a symptom of alternator trouble, it’s best to get to the shop. Addressing the issue quickly can help you avoid inconvenient breakdowns. At Yanis Foreign Auto Repair, we provide expert European alternator replacement and auto electric repair in the greater Hyannis, MA area. Here’s a look at five warning signs of an alternator problem.


Dimming Headlights/Interior Lights

If you notice that your headlights or interior lights are dimmer than usual, it could be a sign of alternator trouble. The alternator is responsible for providing power to these lights, so dimming may indicate that it's not functioning correctly.


Dashboard Warning Light

One of the most obvious signs of alternator trouble is the illumination of a dashboard warning light. This light commonly looks like a battery symbol and indicates that the battery is not charging properly. If this light comes on while driving, it's a sign that you should have your alternator checked by the mechanic.


Strange Noises

A failing alternator can produce unusual noises, such as a whining or grinding sound. These noises can occur due to a belt issue or worn-out bearings. If you hear any unusual sounds coming from the engine area, it's best to have the mechanic take a look.


Battery Issues

While the battery and alternator are separate components, they work closely together to enable the proper functioning of your vehicle's electrical system. If you've recently replaced the battery but continue to experience issues with starting or electrical components, it could be a sign of alternator trouble. A failing alternator may not be able to recharge the battery adequately, leading to repeated battery drain.


Electrical Accessory Problems

Since the alternator powers the electrical systems in your car, issues with it can lead to problems with accessories. You may experience issues such as malfunctioning power windows/seats, or erratic operation of the radio or air conditioning.
