Re: Help with rough idle and acceleration - TIA
 

Obviously. That has squat all to do qith the current path I describe.
The coil secondary HAS NO GROUND - being effectively a transformer,
that's allowed. Current will flow from one end of the secondary,
through one plug to ground, from ground through the second plug then
back to the other end of the secondary coil. Simple isolation
transformer secondary winding case - done all the time. All that's
slightly unusual here is that part of the secondary circuit is accross
2 spark gaps.
