I've read that we should start all airplanes with a split master
switch that way. Turning on the alternater half of the master
energizes the field windings of the alternator, which just wastes
battery power and heats up the alternator. I've been starting planes
that way for many years now. Once the engire starts I bring the
alternator on line by turning on both halves of the mater switch.
Every Cherokee, Cessna and Bonanza I've been in has a split master,
but as I recall the Mooney 201 and 231's I've flown do not-- it's
either everything on or nothing on.
