What Are the Signs of a Failing Alternator?
If your car’s alternator is starting to fail, you may experience a variety of electrical issues that can leave you stranded if not addressed quickly. The alternator is responsible for charging your battery and powering the electrical systems in your car, so when it starts to go bad, you’ll likely notice some warning signs. But how can you tell if the alternator is the issue?
Let’s look at the key signs of a failing alternator and what you should do if you notice any of them.
Key Warning Signs of a Failing Alternator
- Dim or Flickering Headlights
- Warning Signs: One of the earliest signs of a failing alternator is dim or flickering headlights. As the alternator struggles to provide power, the lights may lose brightness or flicker, especially when driving at night.
- What to do: If you notice dimming lights, it’s time to get a battery and alternator check to ensure your electrical system is functioning properly.
- Dead Battery
- Warning Signs: While a dead battery could simply mean your battery needs replacing, it could also indicate an alternator problem. If the alternator isn’t charging the battery, it will eventually lose power.
- What to do: If you frequently need jump-starts, it’s a sign the alternator may be failing. Book a diagnostic inspection to check if the alternator is the root cause.
- Electrical Failures
- Warning Signs: A failing alternator can cause electrical systems to act erratically. You might notice malfunctioning power windows, door locks, or dashboard lights.
- What to do: Electrical issues often point to an alternator problem. If you notice any electrical malfunctions, schedule an alternator inspection.
- Strange Noises
- Warning Signs: A failing alternator can make strange noises, such as a whining or grinding sound. This happens when the internal bearings wear out or the belt becomes loose.
- What to do: Unusual noises under the hood are never a good sign. If you hear whining or grinding, book a mechanical inspection to prevent further damage.
- Warning Light on the Dashboard
- Warning Signs: Many cars have a dashboard warning light shaped like a battery that illuminates when there’s an issue with the charging system, including the alternator.
- What to do: If the battery warning light comes on, don’t ignore it. Book a battery and alternator inspection to diagnose the issue before the alternator fails completely.
