Question

Quizplus · Accepted Answer

The starter solenoid or relay uses a small amount of current from the ignition switch to control a large amount of current needed to operate the starter motor. This allows the vehicle's starting system to function efficiently by controlling the high current flow to the starter motor with a much smaller current triggered by the vehicle's ignition switch.
