Here's how it works:
* Battery: The car battery stores electrical energy.
* Ignition Switch: When you turn the key to the "start" position, the ignition switch completes a circuit, allowing the battery's power to flow.
* Starter Solenoid: The ignition switch activates the starter solenoid, which is an electromagnetic switch. The solenoid engages a gear in the starter motor.
* Starter Motor: The starter motor is an electric motor that uses the battery's power to turn the engine's crankshaft. This rotation compresses the fuel-air mixture, causing combustion and starting the engine.
Once the engine starts, the alternator takes over the task of supplying power to the vehicle's electrical system and charging the battery.
