Circuit Condition - Start
With the start-run-stop switch (SW1) held in the START position, wire 17 is internally closed to ground via wire 0. By
grounding wire 17, current is allowed to flow through the SCR and energize the SCR coil. The SCR contacts internally
close wire 13 to wire 16. Wire 16 then delivers battery voltage to the starter contactor (SC) on the starter motor (SM).
The SC is energized and the contacts close, delivering battery voltage to the starter motor and the engine will start
cranking.
