Thanks to AirEupora and Specialeffects for the offer of pictures, I have e-mailed
you both with a request, off list.
It is a shame that posting pictures to the forum is not working at present, lets
hope the Administrators sort out this problem in the near future.
In the meantime, to overcome this problem, when I have wanted to post pictures,
I have put the pictures in a file in Dropbox, and posted the link here.
Hope this tip helps others.

I still believe that a simple transparent hose with water in it must be far superior
to any other means of measuring, however hi-tech it is!
With this method you get to avoid any possible instrument-to-jig inaccuracies and
you will practically have an infinite resolution.

Hi Will,
If you are using the minimalist Europa power system, then in general, your
surmise is correct. The battery supplies power to the "grid" when the
alternator produces less than the charging voltage (say 12V for the sake of
simplicity). When the alternator generates its full voltage or approximately
13.6V, it pushes energy back into the battery and is the source of buss power.
That being said, I have seen a few very crazy things done in OBAM aircraft.
Also, I dare say no one outside the UK uses the exact design provided by
Europa. My own power system uses a "carefully" considered modification of Bob Nuckolls'
designs. The advantage of going beyond the minimalist
design includes mainly removal of critical single point failure nodes and the inclusion
of secondary sources (I have a second alternator and battery for
the EFIS as I used to do IFR ops).
I have also recently seen crazy things done to other engine systems. A local elderly
gent with a kitfox installed a shutoff valve in his oil reservoir return
line deep inside his cowl to prevent sumping after shutdown. Of course, he
eventually forgot to reach in and turn it back on at some point and completely
bricked his 912s.
This is why I ask for design as built when people ask for troubleshooting help.

Interesting design addition you mention. Understand your point.
Actually I am going for minimalist Europa System. So thanks I just
wanted to check that I had the fundamentals correct.
I do have a Dynon but that has its own battery and I have a good handheld
and a portable GPS so I figure that from the avionics side I am ok.
Incidentally I fired the dynon and the electrical system up yesterday and
it talked to all the devices and no sparks or smoke. The radio worked fine
as well.
My turbo rotax 912 has a mechanical pump as well as the electric pumps.
So I think that I am going to stick with simple.
many thanks again will
William Daniell

No Bob,
The original round section bar was replaced with a much thinner section
flat bar, allowing it to work in the reduced space within the door frame.

Hi Will,
I realize that you did not inquire of design advise, but I will offer some
anyway. The dirt simple electrical system in the combined builder's manual
has a single 30A SloBlo fuse between the battery and the 914 fuel pump.
If that goes, there is no other way to power the pump and bye bye. I really
hate single point fatal errors. It was bad enough that I had to deal with them
in my day job!

Ah thanks.much appreciated. All advice gratefuly received. I have learned
so much from reading the posts of others.
I have one pump connected direct to the alternator and the other to the
bus. (As well as the mechanical pump which is good for 22" map).
Would that be ok?

| Subject: | Re: Dynon AP Panel Trim function |
Just to follow on this note in case anyone is wondering.
I fitted my Dyon AP panel and retained the original LED display. I ve
tested it and both trim and LED work fine.
In principle the AP panel drives the trim and the LED receives the location
from the the servo unit. The two systems are separate although they share
multiwire cable to the servo in the rear of the aircraft. So the white
wires from the servo connect to the AP panel and are used to power the trim
motor. The other wires (green orange blue) are used to provide the trim
position signal to the LED indicator. The LED indicator also has you would
expect power and ground.
I used a different switch from the ray allen one wired per the dynon
instructions
