once the LHS shower of sparks mag is removed the advance/retard breakers
arent in play, nor the induction vibrator (as you say) which is energised on
when start is engaged.

bad for the engine). This assumes the PMag has variable timing and the grunt
to produce a hot spark at low RPM (I know its electric, but dont know how they
function during starting).

Id put it back on the left so the system architecture is logical (depending
on whether you have independent switches for the mags or rotary switch).

whether to do this, or purchase another PMag. In the meantime, I have
a non-impulse Bendix mag that I was thinking of installing as a temporary solution.
I would of course disable/remove the buzz box if this were to happen.

the aforementioned ground be connected to the proposed non-impulse left mag
so that it will ground during start?

The part of Z-101B in black print comes pretty close to Z-Zero if the battery bus
were eliminated. But the electrically challenged novice builder would be
overwhelmed by all of colored options. It would be nice to have architecture
devoted to the simplest possible electrical system while being safe, reliable,
and
easy to understand.
