I'm assuming Z13/8 since you mention 2 alternators.
Need to know more about...
Your primary flying mission?, ($100 hamburgers, frequent long cross
country, aerobatic, low speed local fun flying, over in hospitable
terrain/open water etc)
Type of EI? (Pmag, SDS, Lightspeed etc)
Do you have a mechanical fuel pump in addition to the two electrics?
Do your EI have their own power backup?
Z13/8 shows specific architecture showing how the busses and systems are
laid out. Are you changing the basic architecture?
Will you use fuses, resettable breakers, switched breakers for the EI
and pumps?
That's just a start.

Subject: AeroElectric-List: Wiring RV7 with Z13 diagram (2 alternators,
1 battery)
Hey all,
I am preparing to wire my RV7 iaw the Z13 diagram in Aeroelectric. My
question is, what busses and switches are you using for the system?
The dual ignition should be wired to 2 single pole ignition switches.
Are you putting them both on the main battery bus, the e-bus, or
splitting them between the 2 busses?
There are 2 ECU's. My understanding is there is no need to have them
switch activated, but are you all switch activating them anyway? What
bus are you putting them on? I am thinking that if I put them on the
main battery bus, they should be switch activated. However, if I put
them on the e-bus, they don't need to be...
There are 2 fuel pumps: a primary pump and a secondary pump. Only 1
should be running at a time. I am thinking of also putting them on the
main battery bus with a single dual pole switch (on-off-on). Any other
recommendations?
Thanks!

Both fuel pumps should NOT be controlled by one switch because that switch will
eventually fail. How about two separate switches with a mechanical interlock
so that only one switch can be turned on at a time? Is this a fuel injected
system with high pressure fuel pumps? Can the fuel pressure regulator handle
the flow from two pumps? When designing the electrical system, ask what will
happen if this connection fails? Then either have a backup plan or make sure
the connection is highly unlikely to ever fail.
