A magneto is not like a car ignition, it is the complete circuit from ground
to ground both in the primary and secondary. So points open or closed,
p-lead open or closed will still read <1 ohm circuit to ground.
That's why a test lite won't work on timing the mag. It needs to have an
oscillator to sense the coil/condenser being grounded by the points or not.

Yup, you're right! That's why I retracted my statement and sheepishly
crawled back under my rock  I found my Eisemann mag service manual
and took a look at the schematic (after I first posted). Dang I hate
when that happens (got to me before my morning coffee and my brain's mag
switch was still grounded!)
