reading up m.Mohat articles on the magic of magneto and phase maker ignition may shed some light.

Magazine Articles | Western Reserve Chapter

Phase maker ignition ( like one version of Mercs)  fires by “MAKING” the points close   so a storage capacitor that was previously charged up   is allowed to suddenly dumps  into the coil to fire it.

Conventional OMC  type ignition allows  the  primary coil  and lamintes to load up  like an electromagnet by induce current  from the  effect of magnetism  passing by the laminates (just like a pedal bike  magneto)

but when points OPEN…

the coil tries to mainting itself magnetized but can’t because it has lost the ground referrence  due to  the  points gap.

The collapse  of the magnetized field  induces a reverse voltage (counter EMF)  which tends to rejoin ground  via the points   but ends up in the condenser which is there to protect the points from excess arcs  that burn the surfaces.

At the same time,  the collapsing primary current using the condensers as a storage bin…. induces a voltage in the secondary winding (with  100-200 times the winding loops ) and it also is looking  for a ground and  finds one  by jumping the sparkplug gap. !

SO.. one system  dumps a load of electrons previously  created and stored   like gunpowder  while the OMC  method  dumps electrons  “created”   on the spot by magnetism collapsing.

my understanding anyway .. somebody surely has something else in mind  🙂
