With the Start-Run-Stop Switch (SW1) held in the start position, Wire 15 is now connected to Wire 167. Wire 15 supplies fused battery power via Wire 167 to the Printed Circuit Board. This 12 VDC input signals the Printed Circuit Board to internally ground Wire 229 which is connected to the coil of the Start-Stop-Relay (SSR). This action allows current to flow and the SSR is energized. The normally open contacts close supplying battery power from Wire 15 to Wire 14. Wire 14 supplies power to the Fuel Shutoff Solenoid (FSS), it is energized and fuel is available to the engine. Wire 14 supplies power through Resistor (R1) and Diode (D1) to Wire 4, Wire 4 connects to the field or the Rotor assembly and is used as Field Boost. The second set of normally open contacts also close connecting Wire 15 12 VDC battery supply to Wire 15B. Wire 15B now supplies 12 VDC to the printed circuit board for use with the governor control system. The normally closed contacts now open, Wire 18 is no longer con- nected to Wire 0 and the magnetos are no longer grounded out and can produce spark.
