The alternator has one of the most important roles in the proper operation of the car.
The alternator is a basic component in the car's electrical system. When the alternator does not work as it should, it can lead to much bigger problems. For this reason, the detection of any problem related to the alternator must be done as soon as possible. The diagnosis must be made by an expert within a
authorized car service.What is an alternator?
If you are not an expert in the field, you are surely wondering what this component does and why it is so important. Its role is to supply the car with electrical energy, a process that requires quite a lot of electricity to start the engine. And other parts of the car needed this electrical power that cannot be supported by the battery because it has limited capacity. At the same time, an alternator has the ability to charge the battery when the engine is running. This process can be achieved by converting mechanical energy into electrical current. Because it has to "work" so much, it is normal for its components to wear out over time. Therefore, they will be replaced at some point. The symptoms mentioned below show a malfunction of the alternator. Any verification must be done by an expert.
What causes the alternator to malfunction?
- The most common cause is the loosening of a belt
- The diodes no longer transmit the required voltage
- The alternator bearings are very worn
- A problem in the magnetic field
Symptoms of a faulty alternator:
The earliest sign of an alternator that is not working as it should, is the dimming of the headlights or when they start to flicker. You will notice this either when you accelerate or when you reduce speed. Under normal operating conditions, the light of the headlights will remain at the same level.
If the battery is weakened or no longer works at all, it is a sign that the alternator will fail soon. Even if it can charge the car's battery, the alternator cannot prevent its total failure. If the alternator is defective, the battery will be overloaded and die much faster than under normal conditions.
Some components of the alternator are in continuous motion when you start the engine. If one of these components breaks down or stops working as it should, unusual sounds will be heard. A grinding or crunching sound may indicate a problem with the alternator.
- Problems with starting the engine
One of the reasons why your car either does not start right from the start, or starts more difficult, is a faulty alternator. Of course, a weak or soon-to-fail battery can also be the reason. Therefore, you will have to eliminate the cause related to the battery to consider a faulty alternator.
The alternator is the main source of electricity, so electrical problems can lead to the alternator. These defects can be observed in several ways. For example, the operation of the electric windows is slower than usual. At the same time, the electric door locking system, seat heating or wiper operation can also be affected.
