For the last few days I've been doing other odd things. I cleaned the garage (workshop) and cleaned off and organized the workbench. I ordered a new instrument panel so I am waiting for that to arrive. Once it arrives, I will spend a day or so cutting out all the holes again. I've also placed an order with SteinAir for the panel switches, wiring, terminals, and an additional 6-slot fuse block. Soon I will have everything I need to start wiring the panel so I figured I better start thinking about the basic electrical system! Below is a drawing of the basic system so far.

This drawing is still a work in progress. As you can see, once the key is turned on, the E.I.S. and the fuel flow gauge will turn on. I would want those two on before engine start. The key turns on that bus. Coming from that first bus is a switch (avionics master) that will turn on the second bus in which all the avionics are connected. All the items on this bus would be turned on after the engine is started. I still have to connect the two USB ports but I want those on a hot bus. The idea is that while at Oshkosh or some other fly-in, I could plug my phone into the USB port to recharge it and walk away from the aircraft without having the key turned on.
