What are the reasons for the starter not working?

[DelSkylar]

The reasons for the starter not working: 1. Insufficient battery power or loose connections; 2. Damaged start switch; 3. Short circuit or open circuit in the starter relay coil or burnt contacts; 4. Short circuit or open circuit in the solenoid switch coil or poor contact with the contact disc. The starter is a small gasoline engine equipped with a clutch and transmission mechanism, featuring high power and less susceptibility to temperature effects, capable of starting large internal combustion engines and suitable for extremely cold regions. Starters can be categorized by working principle into DC electric starters, gasoline starters, and compressed air starters. Most internal combustion engines use DC electric starters, which are characterized by compact structure, simple operation, and easy maintenance.
