CIRCUIT CONDITION - START:

With the Start-Run-Stop Switch (SW1) held in the start position, Wire 17 from the Starter Contactor Relay (SCR) is now connected to Wire 0 which is frame ground. This allows current to flow and the SCR is energized. The SCR contacts close connecting Wire 13 battery power to Wire 16. Wire 16 now supplies battery power to the starter contactor (SC) on the Starter Motor (SM), the SC is energized and its contacts close, battery power is available to the Starter Motor (SM) and the engine is cranking.
