Which two functions does the starter solenoid accomplish?

The starter solenoid plays a critical role in the operation of an automotive starter system. One of its primary functions is to move the drive mechanism into position, which connects the starter gear to the flywheel of the engine. This engagement is essential for starting the engine as it allows the starter motor to turn the engine over when the ignition is activated.

The second function of the solenoid is to close electrical contacts that energize the starter motor once the drive is properly positioned. By completing the circuit, the solenoid allows electrical current to flow from the battery to the starter motor, which provides the necessary power to start the engine.

This dual function of moving the drive and closing the contacts is critical for the successful operation of the starting system, ensuring both the physical engagement of the starter and the electrical connection needed for ignition.
