Quizplus · Accepted Answer

The starter solenoid is responsible for engaging the starter motor with the flywheel. If the solenoid is not working properly, the starter motor will not be able to engage and the engine will not crank. The voltmeter reading of 12 volts across the contacts of the starter solenoid indicates that the solenoid is receiving power, but the distinct "click" noise coming from the solenoid indicates that the solenoid is not engaging the starter motor. This suggests that the starter solenoid is faulty and needs to be replaced.
