Your vehicle’s alternator plays a critical role in keeping it running smoothly. The alternator charges the battery and powers various electrical components while the engine is running. When the alternator begins to fail, it can lead to a range of problems that affect your car's performance, making it important to address the issue ASAP. At Integrity Auto Care, we provide expert alternator replacement and auto electric repair in the greater South Beloit, IL area. Here are five common signs that your alternator may be in trouble.

Dimming or Flickering Lights

One of the most noticeable signs of alternator trouble is dim or flickering headlights or interior lights. If the alternator is struggling to provide enough power, your car’s electrical systems may not function properly, causing the lights to dim. In some cases, the lights may even flicker on and off. 

Dead or Weak Battery

While the battery stores power, it is the alternator’s job to keep it charged. If your alternator is failing, the battery may not get the charge it needs, leading to a weak or dead battery. If you find yourself jump-starting your car more frequently than usual; the alternator could be the underlying cause.

Strange Noises

A failing alternator can cause strange noises, including grinding or whining sounds. These noises often indicate bearing or belt problems. Such noises should be brought to the mechanic’s attention ASAP.

Dashboard Warning Light

Most modern vehicles have a dashboard warning light specifically for the alternator or charging system. It may appear as a battery icon, ALT, or GEN light. Ignoring this warning can lead to serious issues, such as being stranded with a dead vehicle.

Electrical Accessory Malfunctions

A bad alternator can cause various electrical malfunctions in your car. You may notice issues with your power windows, stereo system, or air conditioning. These malfunctions occur because the alternator is no longer providing the necessary power to keep the vehicle's electrical systems running smoothly.
