Why Are My Headlights Flickering Constantly

If your headlights are flickering constantly, Stringer Auto Repair advises that this is a sign that the alternator needs to be replaced. The alternator that was installed when your vehicle was assembled will last, on average, 10 years or about 100,000 miles to 150,000 miles. Aside from problems with your vehicle’s lights, we are going to list the other signs that the alternator is bad below.

Constant Discharging Battery

If you constantly have to jump-start your car’s battery because it is discharging, the alternator is no longer able to keep it charged. This is one of the alternator’s responsibilities. We can test both the alternator and battery to find the source of the problem. If the problem is the alternator, we will replace it.

Dashboard Warning Light

You may also end up with the dashboard warning light that will turn off if the alternator is malfunctioning. This light will be in the shape of the battery or spell out ALT or GEN. Bring your vehicle to our shop when the warning light turns on so we can test the alternator right away.

Frequent Engine Stalling

Another sign that your alternator needs to be replaced is if your car’s engine is stalling frequently. This is an indication that the alternator is unable to provide power to the spark plugs so they can fire the air and fuel in the combustion chamber in the correct sequence.

Malfunctioning Accessories

Your car’s accessories will also suffer if the alternator is going bad. A faulty alternator will cause the accessories to malfunction and slow down. For example, it may take more time than normal for your power seats to adjust. You may also have problems with accessories such as your radio or navigation system.

Overheated Electrical System

The alternator can produce too much electricity when it malfunctions. This means it is producing more than the maximum of 14.5 volts. When this happens, you will smell burning electricity coming from the engine. This smell can include hot wires and burning rubber.

Strange Growling Noises

Finally, a malfunctioning alternator may make strange growling noises or grinding noises in your engine. You may also hear squealing or whining if the alternator belt is loose and needs to be tightened. Any strange sounds coming from the engine need to be investigated right away to avoid engine damage.
