Hi all.
I understand the concept of the ignition switch grounding the non-impulse coupled magneto during the cranking cycle. However, in the electrical diagrams for a 1975 Cessna 172M, it does not show to do this, even though the aircraft only has one impulse magneto.
Was this not a thing to do until sometime after 1975?
