The starting system includes a battery, a starter, a traction relay, an ignition switch, and a locking switch (only on cars with automatic transmission) and wires.
When the starter is turned on, current from the battery begins to flow through the starter traction relay winding, the relay armature is pulled in and the relay contacts are closed. At the same time, the relay anchor moves the overrunning clutch with the gear through the lever. The hub of the overrunning clutch rotates on the helical splines of the starter shaft together with the gear, which facilitates its engagement with the flywheel ring gear. Current flows through the closed contacts of the traction relay, supplying power to the stator and armature windings, and the starter armature begins to rotate together with the hub and overrunning clutch.
After the engine starts running, the rotation speed of the pinion exceeds the rotation speed of the starter armature, the overrunning clutch rotates freely and torque is not transmitted from the flywheel to the starter shaft. After the ignition key is released, the power supply circuit of the traction relay winding is opened, the traction relay anchor is pressed back to its original position by the spring, the relay contacts are opened and the drive gear disengages from the flywheel ring gear.
