5 Signs Your Alternator is Dying

Your vehicle’s alternator charges its battery while you drive. Without a working alternator, your car is going to die so if you are out driving and it goes out you will only get in a few miles before the car quits on you completely. You don’t want to be caught alone on a highway or backroad with a broken alternator. To ensure this doesn’t happen to you, keep a lookout for the following signs. 

Dashboard Warning Light

Don’t ignore your dash’s warning lights, they are there for a reason. A problem with your alternator will show up as a little battery or it might say ALT or GEN.

Dim/Flickering Headlights

Power to the car’s headlights comes from the alternator, if they are flickering or dim it means that the alternator isn’t performing correctly.

Electrical Problems

Like your headlights, your car’s electrical system is tied to the alternator. When the alternator goes out, it takes the electrical system, like power windows, locks, dash lights, radio and air conditioner, down too.

Car Stalls/Difficulty Starting

The alternator powers the spark plugs that ignite your engine’s gasoline and if the alternator is expiring, it can’t keep the engine going. Inevitably, your car will go kaput.

Dead Battery

Batteries do die on their own but sometimes it’s the alternator. A bad alternator can drain your battery because it fails to recharge it. If your battery completely dies, and you have more or less recently had it replaced, get your alternator checked.

If your vehicle experiences any of the above symptoms it is worth your time (and money) to get your alternator checked. Many auto shops provide a free inspection and can save you a lot of hassle in the future.

But when something does go wrong, it can be a difficult task trying to work out exactly what that warning light flashing away on your dashboard is trying to tell you. It’s important to know what the car dashboard warning lights actually mean, though, not least because they can pre-empt a car breakdown or full-on failure, potentially saving you from an expensive repair bill and meaning you stay safer on the road.
