1. Prevents the starting system from working when the transmission is in gear. 2. Source of energy for the starting system. 3. Center housing that holds field coils and pole shoes. 4. Locks the pinion gear in one direction and releases it in the other, allowing the pinion gear to turn the flywheel ring gear for starting. 5. Slide on the commutator to carry battery current to spinning windings. 6. Made up of invisible lines of force. 7. Moves into and meshes with the flywheel ring gear any time the starter is energized. 8. Allows driver to control starting system operation. 9. High-torque electric motor for turning gear on engine flywheel. 10. Composed of windings, core, starter shaft, and commutator assembly that spins inside a stationary field.
