CIRCUIT CONdITION - STOP:
With the Start-Run-Stop Switch (SW1) placed in the Stop position Wire 167 is connected to Wire 0 which is frame
ground. The ground signal is supplied via Wire 167 to the Printed Circuit Board. The Printed Circuit Board will
open Wire 229 from ground; this action will de-energize the Start-Stop Relay (SSR). With the SSR de-energized
Wire 14 will no longer have 12 VDC supplied to it through the relay, this de-energizes the Fuel Shutoff Solenoid
(FSS) stopping fuel to the engine. With the SSR de-energized Wire 18 will now be connected to Wire 0, this action
will ground the magnetos out through Wire 18 causing loss of spark to the engine. With the loss of fuel and loss of
spark the engine will shutdown.
