What are the reasons for the starter not responding?

[VanChase]

The reasons for the starter not responding are: 1. There is an issue with the starter's control circuit; 2. The starter's carbon brushes are faulty; 3. The battery does not have sufficient voltage; 4. There is a problem with the relay; 5. Poor contact in the starter's magnetic switch. The function of the starter is to convert electrical energy into kinetic energy when the key is turned to the start position, thereby starting the engine. The components of the starter include: 1. Electric motor: The motor used in the starter is a DC series-wound motor, which converts the electrical energy input from the lead-acid battery into mechanical energy to generate torque; 2. Transmission mechanism: Composed of a transmission sleeve, one-way clutch, and drive gear, its function is to transmit the electromagnetic torque of the motor armature to the engine flywheel during startup to start the engine; 3. Control device: Also known as the electromagnetic switch, its purpose is to connect or disconnect the starting current, allowing the drive pinion to engage or disengage from the flywheel gear ring.
