Avoid mechanical breakdowns on the side of the road by knowing what the signs are of an alternator failure. Knowing this information will help to keep you and those who you care about safe from potential accidents caused by a fault in the alternator.

Keep Your Eyes Open

An alternator failure will lead to your engine becoming useless and even dangerous. Catching the failure early on is the best way to ensure a speedy and successful repair period for the car. All cars do have a light that appears as “ALT” or “GEN” which warns you that there is an issue with the alternator and a clear sign to take the car in for a check. Other than the light here are 3 other signs of failure:

Dim or Flickering Headlights

The alternator supplies power to your car’s headlights. If you notice that they seem dim or flicker regularly it would be best to have it checked. This could mean that there is something faulty with the alternator and ultimately lead to failure.

Difficulty Starting and/or Stalling

Cars require electricity to function. The alternator provides the power to the spark plugs which ignite the gasoline when starting the engine. When there is difficulty starting the car or persistent stalling it could be a sign that a failure is imminent. Be sure to take the car in for a check-up and fix the issue.

Battery Stops Working

As you drive around your alternator is working to help recharge your battery. Sometimes when the alternator is failing it could cause the battery to drain. Eventually, your car is unable to start as the battery is no longer storing any power. Though other faults can lead to battery failures it is often linked to the alternator.

We certainly hope this quick list of what signs to look out for in terms of an alternator failure was useful to you. Please do share if you know of anyone who may benefit from this information. See our list below of related articles that might be of interest to you:

Why Investing in an Extended Car Warranty is a Good Idea

An extended car warranty is a vehicle service contract meant to alleviate the stress and cost of car ownership. They keep your car’s critical parts covered in the event of a mechanical breakdown. The vehicle service contract exists between you and the provider where both parties need to uphold their side of the agreement. Basically this means that as long as you stick with your car’s maintenance schedule, the provider makes sure you are covered when those mechanical failures occur.

What does an Extended Car Warranty Cover?
