Stop Circuit
To stop the engine, the stop switch is closed al-
lowing the capacitor charge current from the sta-
tor to drain directly to ground. NOTE: The CDM
contains a zener diode (not shown for clarity).
This diode prevents overcharging of the capaci-
tor (and possible failure) if the SCR does not re-
ceive a trigger pulse.
