switch on the instrument panel, the shift lever is
moved against spring tension. By means of the guide

the flywheel ring gear.
pinion meshes with the flywheel ring gear
After the
teeth, the solenoid contact disc closes the circuit and
the engine is cranked. When the engine starts, the
speed of the rotating flywheel causes the pinion to
over-run the clutch and armature. The pinion con-
tinues to be engaged as long as the shift lever is kept
in the cranking position.
