Buly,
I'm using a split master switch (Cessna style), but
the right half is the alternator, as in a Piper or
Cessna.  I've actually given some though of rewiring
the alternator, and splitting the two master relays
between the 2 switches.  The one for the engine
systems though will still be a single failure point,
So I'm not sure what I'm gaining.  I guess if I still
had avionics and I/P I'd still have Comm and Nav.
