Patience Grasshopper... the bamboo doesn't grow in a day. I believe they are basically a pair of switching transistors which turn the current on and off to the ignition coils. The pulser coils output has to be amplified enough to poer the ignition coils primary circuit. If I see it right the pulser coil switches the transistor which takes very little power while the transistor in its turn switches the primary winding on the ignition coil. On the older style 'Wings with points the points replaced the pulser and ignitors, the points could handle the current load of the coils directly. The problem was arcing and wear on the points. Replacing the points with pulser coils and transistor switches made forbetter controlled timing, no mechanical wear changing the timing, and longer life.
