switch SW (SW when grounded, electronic ignition is not firing). PC made contact with the coil, trigger voltage through BG1, BG2 by the input IC 2,7 feet, so 10 feet trigger is generated by R1, R2 partial pressure is applied to the SCR control electrode, so that conduction. C1 discharges through SCR, so IGN produce a higher voltage through the ignition coil, spark plug discharge engine. The circuit has a time adjustment circuit, enables the ignition timing varies with engine speed automatic synchronous tracking adjustment, the engine speed is always the best time it needed to ignite.
