The alternator is a device that generates alternating current. Since the battery must be charged with direct current, a rectifier is needed in the alternator system. This role is fulfilled by the diode plate, which is part of the car alternator. 

The proper functioning of the diode plate is extremely important for the entire electrical system of the vehicle. It is well known that a battery without charging quickly depletes, effectively preventing further driving. Therefore, it is important to maintain the alternator, along with all its components, in the best possible condition. A symptom of faulty diode plate operation is incorrect battery charging voltage. However, this is a very general symptom and also corresponds to malfunctions of other alternator components. It is recommended to entrust a more accurate diagnosis of this system to specialists.
