I have a fuse box right next to the alternator and
the coil power comes right off that and travels about 4 inches to the
coils. Minimizes the length of run of those noisy wires and they never
leave the FF area.
Definitely good from noise perspective;
but how about disable capability for verifying coil operation?

While I agree (and indeed use my CB in much the same
manner - particularly
when trouble shooting), it still seem strange that the manufacture of those
type aircraft would spend considerable costs to use 10's of dozens of
circuit breakers in each aircraft (and perhaps hundreds of aircraft
manufactured) where a much cheaper/lighter fuse would do the job (just pull
the fuse for maintenance). But, again this is an area where each can
choose
the approach which makes them feel more comfortable.
I certainly agree that a fuse of CB can do its fundamental purpose of
protecting a wire from cooking - so functionally its a wash, cost and
complexity do vary between the two approaches. But, I think this
again
brings it back to what makes you feel comfortable when flying behind your
rotary engine.
Going out to fly this wonderful morning
