What is the normal voltage output of a car alternator?

[StAugust]

The normal voltage output of a car alternator ranges between 13.5V and 14.5V. Here are detailed specifications about automotive alternators: 1. Working Principle: When an external circuit energizes the excitation winding through brushes, it generates a magnetic field and simultaneously magnetizes the armature into N and S poles. 2. Maintenance: Regularly clean accumulated dirt and dust from the alternator surface to maintain cleanliness and ensure proper ventilation. Periodically inspect the tightness of all fasteners related to the alternator and promptly tighten any loose screws. 3. Function: The car alternator serves as the primary power source for vehicles. Its role is to supply electricity to all electrical equipment (except the starter motor) while the engine is running normally, and simultaneously charge the battery.
