Starter
Get off to a good start
A car starter is actually a small motor. The starter and solenoid engage the flywheel and turn the gear, causing the engine to start when you turn your key to the right position, or press the ignition button.
The solenoid is an electric relay that sends current from the battery to the starter, so the battery must have sufficient power to initiate the process.
Though simple, the whole process requires precise electrical components so the starter is able to operate during hot summers or on bitter cold winter mornings.
