It may be my brain that is missing the connection, but I don't see the electrical
path that feeds bus power to the LR3. The pole called upon to switch bus power
goes nowhere.
Shouldn't the arc path of pole 5 be connected to terminal 4, replicating pole
2 and terminals 1 & 3?

the 'panel' ground bus is normally on the cabin
side of the firewall. I think I'm going to
change the name to 'cabin ground bus'. The avionics
ground is on the panel, centrally located to electro-
whizzies that reside on the panel.
Don't need a fuse block for the 'battery bus'. Put
the clearance delivery relay right close to the
battery contactor. Use a 3a inline fuse to feed
the pmag.
Getting ready to launch for Enid . . . we
live 100 miles from everywhere . . . got some
shopping to do.
We'll be back tonight.

I=99d suggest not posting your electrical ideas on VAF. You=99ll
get 100 different opinions. Here most folks are on the same sheet of music.
These Z figures work and can be modified to meet your goals.

That's a progressive three-position switch, off, battery contactor on, battery
contactor and main alternator on.
Ref the paragraph heading "Switches" in Chapter 1, and notes 15 and 22 in Appendix
Z of Aeroelectric Connection book.
