This schematic here is the starting motor circuit diagram for the 1934 Chevrolet cars. The starting system has only one function to perform, it cranks the engine in the same manner as was formerly dome by hand. In the starting system there are three components: battery, starting switch, and starting motor. The battery supplies the energy, the switch completes the circuits, allowing this energy to flow to the starting motor, the motor then delivers mechanical energy and does the actual work of cranking the engine. The starting equipment is used for a shirt time only and then remains idle until it is again needed to start the engine. Click on image to view it larger in a new tab.
