Your vehicle's alternator is responsible for keeping the battery charged and powering essential electrical components while the engine is running. When the alternator starts to fail, it can cause a range of issues that may leave you stranded if not addressed promptly. At Everett Transmission & Auto Repair, we provide expert alternator replacement and auto electric repair in the greater Everett, MA area. Here are five common signs of an alternator problem.

Dead or Weak Battery

While a dead battery is often attributed to the battery itself, a failing alternator can also be the culprit. If the alternator isn't charging the battery properly, the battery will eventually drain and fail to start the vehicle. If you've replaced the battery recently and it's still losing charge, the alternator could be the root cause.

Dim or Flickering Lights 

One of the most noticeable signs of a failing alternator is dim or flickering headlights and interior lights. The alternator provides power to the vehicle's lighting system, and when it starts to fail, it can't deliver a consistent power supply. This is a clear indication that your alternator may not be functioning properly.

Warning Light on the Dashboard 

Modern vehicles are equipped with a dashboard warning light that signals alternator issues. This light typically appears as a battery icon or reads ALT or GEN. If this light illuminates, it’s a warning sign that the alternator isn't charging the battery correctly. Ignoring this light could result in a dead battery and a stranded vehicle.

Malfunctioning Electrical Accessories

When an alternator begins to fail, it can cause electrical components to malfunction. You might experience power windows operating slower than usual, the radio cutting out, or the air conditioning not functioning properly. These electrical failures occur because the alternator isn't supplying sufficient power to these systems.

Strange Noises 

A failing alternator can produce unusual noises, such as grinding or whining sounds. These noises are often caused by a worn-out bearing or a faulty belt. If you hear any strange sounds coming from the alternator area, it's important to have it inspected by the mechanic as soon as possible.
