How to Test if the Generator is Not Generating Electricity?

[DelAddyson]

Testing methods for a generator not generating electricity include: 1. Using a voltage meter; 2. Connecting an external ammeter; 3. Using a car bulb as a test lamp; 4. Removing the battery ground to check if the engine operates. The function of the generator is to supply power to all electrical devices except the starter when the engine is running normally, while also charging the battery. The generator is the main power source of the car, and its working principle is: when the external circuit energizes the excitation winding through the brushes, a magnetic field is generated, and the claw poles are magnetized into N and S poles. Methods for generator maintenance include: 1. Testing the generator on the vehicle without disassembling it to determine if there is a fault; 2. Using a multimeter voltage setting for testing; 3. Using an external DC ammeter when there is no ammeter on the car dashboard.
