5 Common Symptoms of Alternator Failure

Autobahn Specialists • 20 December 2023

Your alternator is responsible for charging the battery and supplying power to the electrical system, making it an essential component for the proper functioning of your car. If you suspect an issue with your alternator, it’ll be best to bring it to the mechanic’s attention ASAP. Otherwise, you could end up finding yourself stranded. At Autobahn Specialists, we provide expert European alternator replacement and auto electric repair in the greater Tacoma area. Here are five warning signs of an alternator problem.


Dimming or Flickering Lights

In a lot of cases, an early sign of alternator issues is the dimming or flickering of lights, both inside and outside the vehicle. As the alternator generates power, it provides a consistent flow of electricity to electrical components. If you notice your headlights dimming or dashboard lights flickering, it may be a sign that the alternator is struggling to maintain a steady power supply.


Strange Noises

Unusual noises coming from under the hood can indicate alternator trouble. A worn-out alternator may produce grinding, whining, or squealing sounds, suggesting issues with components such as the bearings or the belt. 


Warning Light on the Dashboard

Oftentimes, the first sign of alternator trouble is an illuminated dashboard warning light. Commonly, this warning light flashes on as a little battery-shaped icon. It’s always best to bring warning lights to the mechanic’s attention before the underlying problem escalates.


Difficulty Starting the Vehicle

A struggling alternator can result in an undercharged battery, making it difficult to start your car. If you find yourself needing to jump start your car or experiencing sluggish engine cranking, the alternator may not be providing sufficient power to keep the battery charged.


Electrical Accessory Failures

The alternator powers various electrical components in your vehicle, such as the radio and power windows. If you notice these accessories malfunctioning or working intermittently, it could be a sign of alternator issues. A failing alternator may not provide enough power to sustain all electrical systems simultaneously.
