Your vehicle’s alternator plays a crucial role in keeping its electrical systems running smoothly. It charges the battery and powers essential components such as the lights, radio, and air conditioning while the engine is running. If the alternator starts to fail, it can cause a range of problems that, if ignored, could even leave you stranded. At East Windsor Auto, we provide expert alternator replacement and auto electric repair in the greater East Windsor, CT area. Here are five warning signs of alternator trouble. 

Dimming or Flickering Lights

One of the most noticeable signs of alternator trouble is dimming or flickering headlights. Since the alternator supplies power to the vehicle’s electrical systems, if it’s malfunctioning, it may not provide enough power to fully illuminate the lights. You might also notice dimming interior lights or dashboard lights behaving erratically.

Dead or Weak Battery

Although the battery is responsible for starting your car, the alternator keeps it charged while the vehicle is running. If your alternator isn’t working properly, the battery may not be able to hold a charge, which can lead to frequent jump starts. 

Electrical Accessory Malfunctions

When the alternator is failing, it can cause other electrical components to behave erratically. You might experience power windows or seats moving slowly, issues with the radio cutting out, or malfunctioning power locks. If these problems occur together, it’s a sign that your alternator may not be providing enough power to run all the systems properly.

Unusual Noises

A failing alternator can sometimes produce strange noises, such as grinding or whining sounds. This can happen due to worn-out bearings or a loose belt. If you hear unusual sounds coming from the engine bay, it’s important to have your car checked ASAP.

Warning Light on the Dashboard

Many vehicles are equipped with a dashboard warning light that indicates issues with the charging system. This light often looks like a battery symbol or says ALT or GEN. If this light comes on while driving, it’s a sign that your alternator may not be charging the battery properly. Ignoring this warning can lead to more severe problems.
