In the below circuit,
170 is a Q401E3 Triac: http://www.mouser.com/ds/2/240/E2Triac-18233.pdf
The capacitors are ceramic disc.
The Triac is rendered normally conducting when
S1 is open.
When I close
S1 the Triac is still conducting when I don't want it to be.
I'm not sure what is wrong or how to fix it; would appreciate any help. The only thing I can think of that is happening is that the path from Engine Magneto to ground through the
S1 switch is of a lower impedance therefore making the Triac useless in the circuit below. The point of the circuit was that when
S1 closes, it allows the spark plug to ignite.
Edit: circuit based on patent
