The ignition vibrator is connected to both the switch(p-lead)lead and
the start/retard lead on the "starting" magneto and is only going to
operate when the main contacts AND the start/retard contacts in the
magneto are "open". The condensor is connected across the main
contacts. If the wire was shorted to the case, both contacts would be
connected to "ground" regardless if they were open or shut.

The ignition vibrator is only connected to the "low" side of the
magneto, and the pulsating voltage from the vibrator directed into the
low side of the coil induces the spark out of the "high" side.

I gave you wrong information. It was not the lead from the condensor --
rather it was the primary lead from the coil (coil to points) that was
possibly shorted out.

How does that change your analysis?

Thank you.
