Dave-
Get Bob Nucholls book the aero electric connection- he has all of the
schematics in there for dual bus dual battery, dual bus dual battery/dual
alternator..

  Iam also going all electric on my chevy V8.  I will have the Blue Mtn.
system with dual alternators.  I would be interested in the set up of the
dual bus.  Dave B.

    I'm going all-electric with my XL.  I'm just starting the engine
installation phase of my project, using a mock-up of an IO-540D.  Redundancy
is so cheap and easy to do with electrical, I wouldn't bother dealing with
the hassle of installing and maintaining a vacuum system.

    If you go all-electric, it's vital to include a system providing active
notification of low voltage, so you have the capacity of your battery(ies)
to keep the important electrical stuff going while you decide where to land
if your (main) alternator should pack it in.  With modern sealed lead-acid
batteries, this could well be as long as your total fuel endurance!  As
other have already noted, you will find the information you need in the
AeroElectric Connection, available from http://www.aeroelectric.com/ .

    I'm planning a dual-bus, dual battery ("small" SLA batteries), dual
alternator (60 amp belt-driven main, 8 amp backup on the vacuum pump pad)
electrical system.  The goal of having electrical system reliability better
than the reliability of just about any other system in the plane is easily
within reach, at no great cost.

    I probably won't use spinning-mass gyros.  There are many options now
available for solid state attitude and heading at about the same cost as
conventional gyros, but with far less potential for reliability problems.  I
doubt that the manufacture of spinning mass gyros will persist for more than
a few more years.

      Is there any one out there who put a vacuum system
      on an auto conversion? I have a Chevy V8
      installed and would like some ideas on how other people
      attacked the Vacuum system. I thought of a electrical
      driven vacuum pump but do not know how much
      vacuum I need to pull. I bought a engine driven aircraft pump. But
with it I need to find out what Rpm  it needs to be run at? Where it mount
it ?And how I might install it.
      Or should I just give up on the vacuum system all to gerther
      and go all electrical.

      Thank you Wise ones
      Ron
