Top Signs of Alternator Failure

McKonly's Garage Blog

A healthy alternator is needed to keep your engine full of juice and cruising down the road. It's what generates the power when you start up your vehicle and is also responsible for keeping your accessories properly functioning. Here's a look at five signs that could you need alternator replacement.

Dashboard Indication

Vehicles usually have a set of indicator lights on the dashboard that will tell you if there's a problem with your alternator or charging system. If this happens, you might see the letters ALT or GEN turn on. Often times this will be the first sign of an alternator problem and means you'll want to soon get the issue checked out.

Dead Battery

While it's entirely possible for a battery to die all on its own, if you have a newer one that has died, then you may very well have an alternator problem... so long as you're sure that you didn't leave the headlights on.


A healthy alternator is necessary for your pistons to keep pumping without the kind of interruption that can leave you stranded.

Dimming or Flickering Headlights

When navigating through the darkness, it's your alternator that is keeping your headlights powered. If your headlights are flickering or dimming, then you have reason to suspect an alternator problem.

Failing Electrical Accessories

Issues with power windows, the radio, and other electrical accessories can be symptomatic of a failing alternator.
