How to Determine if the Generator is Faulty?

[ClaytonLee]

To determine whether the generator is faulty, follow these steps: Start the engine to keep the generator running and use a multimeter to measure the battery voltage. At this time, the battery voltage should be between 13-14.8V, indicating that the generator is in good condition; if the battery voltage remains unchanged after turning off the engine and stopping the generator, it indicates a problem with the generator. Relevant information about the car generator is as follows: 1. Introduction: The car generator is the main power source of the vehicle. Its function is to supply power to all electrical equipment (except the starter) while the engine is running normally, and simultaneously charge the battery. 2. Structure: Based on the three-phase stator winding of a conventional AC generator, the number of winding turns is increased, and lead-out terminals are added, along with an additional three-phase bridge rectifier. At low speeds, the output is provided by the original winding and the additional winding in series, while at higher speeds, only the original three-phase winding provides the output.
