Gee, the whole bloody thing is a switching amplifier. No way in hell that pickup is going to turn the coils on and off all by its lonesome. Primary voltage in the coils is probably close to 50-60 volts at peak, and the supply voltage is only 4.8-6. Okay. . inductive "kick" makes the spike, but the miniscule .5-1 volt signal from the pickup would never result in a coil firing if the module was not amplifying that signal to saturate the coils during on dwell time.


BTW your "module" and the CH, 3W, and DA ignition modules all use the same basic circuitry to fire the coils. Just a simple switching amp that has the timing of its pulse controlled externally, by a Synchrospark module, mechanical advance, or the auto-advance circuits in the pickups on DA and 3W engines.

you could probably hook up a synchrospark advance/retard unit on the input side of a DA./3W style ignition and it would keep time just fine, thank you very much.
