Symptoms of a Failing Alternator: Expert Advice from Cañon City's Auto Repair Shop | Zerby Automotive

April 17, 2024

At Zerby Automotive, located in the heart of Cañon City, CO, we understand the importance of maintaining a healthy vehicle. One critical component that often gets overlooked until it's too late is the alternator. As your trusted local auto repair experts, we're here to guide you through the symptoms of a failing alternator, helping you to keep your car running smoothly and reliably.


What is an Alternator and Why is it Important?

The alternator is a pivotal component of your vehicle's charging system. It works with the battery to power the electrical components of your car, including the lights, radio, and dashboard computer. When the alternator is in good condition, it charges the battery while you drive, but a failing alternator can lead to a multitude of issues, potentially leaving you stranded.


Recognizing the Symptoms of a Failing Alternator

  1. Dimming or Flickering Lights
  2. When your alternator begins to fail, it can no longer consistently power your car’s lights. If you notice your headlights or dashboard lights dimming or flickering, especially at low speeds or while idling, this is a classic sign of alternator trouble.
  3. Warning Lights on the Dashboard
  4. Most modern vehicles include a battery or alternator warning light on the dashboard, usually depicted as a battery symbol or the letters “ALT.” If this light stays on, it's a direct signal from your vehicle’s diagnostic system that the alternator needs to be checked.
  5. Battery Problems
  6. While the battery starts your car, the alternator keeps it running. If your battery is frequently dead, or your car struggles to start, your alternator might not be charging the battery properly.
  7. Strange Noises
  8. Alternators have several moving parts that can wear out. If you hear grinding or whining noises coming from the engine, it could be due to bad bearings or other failing components within the alternator.
  9. Electrical Failures
  10. If you start experiencing problems with various electrical components in your vehicle, such as power windows, wipers, or heated seats, it could be a sign that your alternator is not delivering enough power.
  11. Burning Rubber or Electrical Smells
  12. A malfunctioning alternator can cause excessive friction or heat, leading to smells reminiscent of burning rubber or hot wires. If you catch a whiff of something burning under your hood, it’s important to have your vehicle inspected immediately.
