For those of us with (small) alternators, batteries, no starters, but with dual slick/bendix mags, my wiring is pretty straight forward.
Anyone have any diagrams showing how one might power a p-mag off the battery but not off the master so it is not being powered full time? I believe p-mags will self-excite after a certain low(?) RPM, so is it as simple as wiring a completely separate mag bus that comes directly off the battery, then turning it off after startup? I hand prop with the master off and don't bring the avionics alive until ready to taxi, but would need to excite the mag enough to let me hand-prop...
