How to Determine if the Generator is Faulty?
1 Answers
Distinguishing whether the generator is faulty can be done by: 1. Starting the engine, keeping the generator running, and using a multimeter to test the battery voltage; 2. If the battery voltage is between 13 to 14.8v, it indicates the generator is in good condition; 3. If the battery voltage remains unchanged after turning off the engine and stopping the generator, it means the generator is damaged. The car generator is the main power source of the vehicle, functioning to supply power to all electrical devices while the engine is running normally, and simultaneously charging the battery. Reasons for the generator not producing electricity include: 1. Diodes being broken and not rectifying; 2. Brushes stuck in the brush holder; 3. Rotor's magnetic field winding not receiving power; 4. Stator windings short-circuited or grounded; 5. Rotor's claw poles becoming loose.
