I have drawn up a basic electrical drawing for my Sonex. I just want a
simple system that will be ok for a VFR only aircraft. I am very much a
newbie when it comes to aircraft electrical systems and all I really know
is what I have read in The AeroElectric Connection. I would like some of
you more knowledgeable folk to have a look at my drawing and make comment
on it. Is the wire sizing adequate? Does it require any inline fuses? What
about where the alternator circuit is connected? My thinking here was it
would be better to be able to disconnect alternator power to the cockpit
by turning off the master switch, than disconnecting alternator power to
the battery.
Please feel free to say what you think, the more opinions the better.
Cheers,
Tim.

What you've drawn will function as advertised but
I'm curious as to why you did not adopt a version
of Z-16 . . .
http://www.aeroelectric.com/PPS/Adobe_Architecture_Pdfs/Z16M.pdf
. . . your proposed system has no control over the
alternator, no ov protection. I presume that your
EIS has some form of low voltage warning but if not,
that should be a component of your design goals as
well. The choice of ignition/starter controls doesn't
impact functionality. Z-16 with the e-bus removed
seems more suited to service in the small airplane.
