5 Signs of a Failing Alternator
Your car's alternator provides power to keep everything running smoothly. However, when it starts to fail, it can cause a variety of problems that may even leave you stranded on the roadside. At The Mobile Wrench Mechanic Services, we can come to you to address your alternator problem. Here’s a look at five warning signs of alternator trouble.
Dimming or Flickering Lights
One of the most noticeable signs of alternator problems is dimming or flickering headlights, dashboard lights, or interior lights. The alternator supplies power to these components, so if it's struggling, you may see lights becoming noticeably dimmer or flickering inconsistently.
Warning Light on the Dashboard
Oftentimes, the first indication of an alternator problem is an illuminated dashboard warning light. This light may come on as a little battery-shaped icon, or with the letters ALT OR GEN. Whenever a warning light comes on, it’s important to bring it to the mechanic’s attention before the underlying problem gets worse.
Weak or Dead Battery
Although the battery and alternator are distinct components, they work closely together. A failing alternator may not properly recharge the battery, leading to a situation where your battery runs low or dies unexpectedly. While there are other issues that commonly cause dead batteries—such as old age or leaving on headlights—a faulty alternator is often to blame.
Strange Sounds
A healthy alternator operates quietly, but as it wears out, you may start hearing unusual noises. A whining or grinding sound coming from the engine area could indicate a belt issue or worn-out bearings in the alternator. Ignoring these sounds could lead to complete failure, so it’s important to address them ASAP.
Electrical Accessory Issues
Beyond dimming lights, alternator problems can cause other electrical issues. You might experience erratic behavior from power windows, a malfunctioning radio, or problems with your air conditioning. These issues arise because the alternator isn't supplying consistent power to all electrical components.
