[Walker]

Automobile alternator damage symptoms include dimming of car lights or dashboard lights; damage to the battery or accumulator. The following are specific details about car alternators: 1. Working principle: When the external circuit energizes the excitation winding through the brushes, a magnetic field is generated, and the electrodes are magnetized into N and S poles. 2. Maintenance: It is necessary to frequently clean the accumulated dirt and dust on the alternator's surface to maintain cleanliness and good ventilation. Regularly check the tightness of all fasteners related to the alternator and promptly tighten all screws. 3. Function: The car alternator is the main power source of the vehicle, whose role is to supply power to all electrical equipment except the starter when the engine is running normally, while also charging the battery.
