I am building a RV-7A and have started to think about the electrical system. I have purchased Bob Nuckolls AeroElectric Connection. My engine will be a Superior XP-320 Plus with carburetor and the LSE Dual Plasma III CDI ignition installed at the Superior factory.I want to install a all electric panel using the Dynon FlightDEK-D180. Bob recommends his system found on Drawing Z-14 which is a double battery double alternator split buss design. Bob and LSE both recommend eliminating the standard "key switch" and replacing with toggle switches.

When starting the airplane, what is the sequence of operation that should take place?
1. Energize primary battery contactor.
2. Energize secondary battery contactor.
3. Energize dual system cross-over contactor which lets the starter use both batteries for starting.
4. Turn primary ignition switch to ON.
5. Turn secondary ignition switch to ON.
6. Push start button
7. Turn primary alternator field switch to ON.
8. Turn secondary alternator field switch to ON.
9. De-energize the dual system cross-over contactor.
Does the preceding sequence make sense? Please advise!

Hole-E-Cow!
I kind of like the old fashion way.
1. Pump the throttle a couple times
2.Advance the throttle a tad
3. Turn on battery
4. Hit the ignition
5. It starts.
