Signs That You Need to Call A Car Alternator Shop

April 15, 2019 3 min read

As a car owner or someone that has access to cars and have a little knowledge of how they work, you may already know that an alternator is the engine room of your car's electrical system. And so, if your alternator starts having any issue at any time, you should do something about it immediately to avoid your car breaking down.

Before we go any further, let's find out what this very important car device is.

What an alternator entails

A car alternator is what charges your vehicle's engine while it is running. The reason for this is to ensure that your car battery has enough juice so that your car can easily start when next you want to start it. Apart from helping your car run smoothly, the alternator also ensures that your car has the right electrical power it requires to function well.

Some warning signs that signifies your alternator is wearing out

You don't necessarily have to visit a car alternator shop before you can tell if your alternator is bad. The following signs below should guide you:

Flickering or dim headlights

If your headlight is acting up by diming or flickering on its own, it is usually because the headlights are not receiving enough power from the alternator. Once you notice this, know that it is time to change your alternator. And, it’s also a good idea to visit a car starter shop to know if they have a good and working alternator.

Unexplained dead battery

Perhaps you replaced your old battery not too long ago only to find out that the new one is also dead. If there is no justifiable reason why your car battery should be dead such as leaving your car light on for a long time or not using the car for several days, and yet, your relatively new battery that has been working perfectly stops working, blame it on the alternator. Most times, a new battery discharges when the car alternator is bad and therefore cannot charge it.

Illuminated indicator or warning light

Some cars or vehicle have an indicator or warning light that starts illuminating when the alternator is not working optimally. If you are observant enough, you will notice when this particular light turns on by itself. If that is the case, make sure you visit or contact a car alternator shop or a car starter shop that can help indicate what the issue is. Don't wait until your car stops working or to hear some sounds before taking it to a mechanic.

Not starting or stalling

When your car is stalling, it could an indicator that the spark plugs are not getting enough power from the alternator. The engine will have difficulty running because there isn't adequate electrician power to keep the car running.

Electrical malfunction

Another way to tell if the alternator is bad is when you start experiencing electrical problems like your locks or power window not engaging appropriately. Your alternator may be calling for replacement.

Unusual sounds

You should never ignore any noise or sound that comes from your vehicle no matter how subtle it might sound. When the alternator bearings in your car starts failing, you will notice a clunking or rattling sound.


The points things listed above are some of the warning signs that indicate that your alternator is bad. Always be observant and look out for such to avoid being stranded from your car breaking down unexpectedly.
