What's the reason for the starter not responding?

The reasons for the starter not responding: 1. Fault in the starter's control circuit; 2. Issues with the starter's carbon brushes; 3. Insufficient battery power; 4. Malfunction of the starter relay; 5. Burnt-out starter fuse. 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 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's armature to the engine's flywheel during startup to initiate 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 ring gear.
Last time I tried starting the engine in my car, I also encountered a situation where the starter didn't respond, which felt quite frustrating. The most common issue is insufficient battery power, especially in cold weather or when the car hasn't been driven for a long time. Battery aging or forgetting to turn off the lights can easily drain it. Another possibility is loose wire connections—check if the battery's positive and negative terminals are securely connected, or if the starter's fuse has blown, as these can prevent current from flowing. A good first step is to try turning on the headlights; if they're dim or don't light up at all, it's likely a battery issue, and you can attempt a jump-start or call for roadside assistance. Don’t overlook the possibility of the anti-theft system mistakenly locking and causing startup failure, which is particularly common in some older cars. Regularly checking battery health and cleaning the terminals can help avoid many headaches.
