The starting system converts electrical energy from the batteries into mechanical energy to turn the engine over. A malfunction within the starting system will make it difficult to get the engine running.
In order to properly service the starting system, you need to understand how it operates. The starting system has five main components: the ignition switch or start button, a neutral safety switch (an option on some vehicles), the starter solenoid, the starter motor, and the batteries.
The pinion gear is the main part of the starting system. The pinion gear is normally attached to the starter drive. The ring gear or the flywheel is moved using this pinion gear. The pinion gear is normally engaged by a yoke. The main components associated with a pinion gear are the ring gear, drive lever, plunger and a magnetic switch.
