Symptoms and Signs of a Failing Alternator

An alternator helps in converting the mechanical energy into electrical energy like an alternating current. Simply put, an alternator is a generator in the car that is crucial for its working. Every part of the car is as important as the other, and the alternator is one of them. Without a working alternator, the electrical system of the car will not function properly. The problem arising in the electrical system might cause more damage that will lead to repair or even replacements. The charging system of the car also will not work if the alternator is bad. The GXOAP overrunning alternator pulley also gives electrical power to the vehicle accessories and the vehicle’s exterior to change all the car’s components. It is secured to the engine and is powered through a serpentine belt. 

Symptoms of a bad alternator: 

• The most common symptom is that the vehicle’s charging system will show issues as the warning light in a battery shape will come on the dashboard. The warning loony comes when the ignition is turned on but should be turned off as soon as the engine starts fully. If the light is on, it is clear that the charging system is facing an issue. It is not a final indication that the alternator is broken, but it’s a very common one. There might be other electrical reasons for the light being there during the engine’s running, and a mechanic should look after the issue at the earliest. 
• The second sign of the weak charging system can be when the dash lights and the headlights go dim while the car is idle but gets bright as soon as the engine gets turned on. The weak alternator or a dying battery can be the reason behind this issue. Moreover, if there are poor connections with the battery terminals or maybe a loose belt, that could also result in a weak system. A buzzing noise from the alternator is also a sign of trouble with a weak alternator. 
• Lastly, the failed plates within the car are also a symptom of a weak alternator. There are rotating plates that create an area for alternators to produce energy. There are three plates, and they can all fail one by one, causing the weakening of the alternator. Though the alternator won’t stop working completely, the output level will fall drastically. The ignition system might die, and the battery will fail. 
• If the car accessories are working slow or malfunctioning, then the reason behind it might be a weak alternator. An alternator who cannot provide enough power to the car’s electronics can often lead to nonworking accessories. For example, if the windows take too long to open or the seat warmers feel “off,” or if the instruments are not working, as usual, there might be a problem with the alternator. 
• If there is trouble in starting the engine, that often means that the alternator cannot charge the battery. Also, if the car stops while driving, then it can mean that the plugs are not receiving enough power from the alternator for its functioning.

How to check an alternator? 

To be sure about the working of the alternator, some test runs can be made to see if there is damage and how badly it is damaged. This will also help in finding out what solution can be used to fix the problem. 

• Use a voltmeter: It is a device used to measure the electrical difference between two points in an electrical circuit. It is an important tool that helps to determine if the alternator is bad.
• By checking the battery, one can find out how bad the alternator has gone. The voltmeter can be used to test the battery and detect where the real problem stands. 
• Monitoring your alternator by checking the alternator gauge will show the output, making it easy to read the levels required to know if the alternator is weak. Next, turn the accessories on to get a more accurate result as it will stress the alternator. Finally, run the engine, and if there is a squealing sound coming, it will indicate a weak alternator. 

Alternators can last longer by keeping it dry. If water gets inside the alternator, then it will wear faster. Coolant or oil leak can also lead to damage to the alternator. Therefore, it is important to keep the alternator and the engine compartment safe from liquid damage. 

Purchasing a good quality alternator, the life of the alternator increases.
