Frank,
I wired my SkyRanger/912UL via Z-16 also. It does the same thing. I just
start the engine with the MASTER in the BAT position and then go to BAT/ALT
after the engine is running, then turn on all loads. Shut-down is opposite
sequence.*
Bob,
I didn't install a diode across the starter contactor coil but plan to.
Will check next time I crank her up to see exactly when it happens and give
you another data point.
Rodney in Tennessee
* I use the "5-M's" mnoemonic to remember shut-down sequence.
...Music - turn off all loads.
...Mags - check.
...Mixture - full lean (for the 912UL I just pull throttle to the idle
stop).
...Mags - off.
...Master - off.

| Subject: | RF noise from EFIS |
Radio,
What kind of EFIS? Not all EFIS systems are created equal! I would bet
that you have a BMA system! If so, I have worked with a few customers
with similar problems. The only thing that helped was to incorporate
shielded wires (which BMA doesn't like to use) and move the antenna away
from the main processor. The BMA stuff makes an unacceptable amount of
RF noise. One of the many reasons they will never get a TSO.

Subject: AeroElectric-List: RF noise from EFIS
<microsmurfer@yahoo.com>
Trying to figure out a problem I'm running into where an EFIS screen
seems to be putting RF noise into my radio.
The noise seems "small" -- as in it can't be heard if there's a strong
signal being received, but can be heard if there's no transmission or as
background while receiving poor signal. It never breaks the squelch on
the radio at all, so it can only be heard if I pull the squelch button
on my SL-40.
noise goes away if antenna is disconnected, in which case all I can hear
is normal radio static.
noise can be heard if rubber ducky antenna is connected instead of the
Comant antenna (so I'm not sure it's my real antenna installation at
issue here, but could be?) Due to the setup I have, I can hook this
antenna right behind the radio, or at the end of the coax run.. didn't
notice any difference between the two.
Tried Radio Shack ferrite choke at various locations and it didn't seem
to do anything.
Tried some RS in-line choke (in-line with radio +, as well as EFIS + and
ground) which also didn't do anything either.
coax doesn't run close to the EFIS screen, and for the most part, it's
not close to other wires.
I have a 2-screen setup and both (and either) produce this noise...
have not tried transmitting, so no idea what kind of impact it'd have
(if any) on outgoing transmissions.. focused on reception at this point.
again, since it doesn't break the squelch, it's not a big big issue, but
it's annoying and would love to see it go away :)
any thoughts?
Thanks!
Radomir

It affects the BMA Sport and Lites as well and is worse in composites than metal
planes.
Actually BMA encourages the use of shielded wires for anything running out of the
EFIS.
As mentioned above you should avoid if possible running any EFIS wiring near your
antenna lines.
Also the can around the EFIS is not necessarily connected to the ground of the
circuit boards so the can itself should be grounded as well as the EFIS.
Look for any wires from the EFIS that terminate in a dead end ( are not connected
to anything) and eliminate them they are acting as a transmit antenna. Likely
culprits are ap disconnect wires on the stick running next to your PTT and
engine monitoring circuits not yet hooked up.
The shield on sheilded cable should be grounded at both ends.
If you are not using a serial port turn it off.
Hopefully you can reduce the noise to a level where it can be overcome with the
squelch setting as noted above.

Thanks guys.. just to clarify a few points:
1) It's not BMA... it's GRT.
2) It doesn't need squelch adjustment -- it never breaks the squelch.. doesn't
even come close to that.
3) It doesn't affect normal transmissions -- those are recieved 5 by 5.. radio
does a great job of getting rid of all that noise when good transmission is
received.
4) coax doesn't run close to any efis wires..
I ended up reviewing BMA message boards, and what I can see there is that BMA guys
are A LOT more affected than I am... I don't have symptoms they're describing
where increasing squelch takes care of the noise...
Thanks again!

I may be asking for a beating here, but exactly why should I create
detailed wiring diagrams? I wired my RV-7A myself following the Z-13/8
schematic, and have relatively easy access to all my electrical compone

All wires are labeled on both ends, indicating where they came from and
where they are going to. I probably should have sketched out the wirin

diagrams as I completed routing each wire, but it can still be done now
without too much trouble since my forward top skin is still off. Ok, I

It's not for your benefit right now. It's for your benefit in 3
years when you scratch your head and wonder what the heck you did
this or that for, and for the next guy who buys your plane and has no
idea what you were thinking. Same reason programmers add comments to
their software.
You should see the undocumented mess I inherited under my panel. The
only way I'll ever figure it out is to take it all apart and put it
back together again. And that will take about a week of
effort. Document it now, and generations that follow will thank you.

Erich,
Food for thought:
If you need your leading edge open now to trace the wiring, think about
where you will be when you close the leading edge, then a year from now,
and 5-years from now. If you cannot draw your wiring diagram now
without even looking at the wiring - don't you think you will be in
trouble down the road? Labeling the wires will help, but there is
nothing like a good diagram to help in understanding an airplane's
electrics.
To save time now - and to make for a winter time project, draw your
diagrams in pencil now and make nice ones for permanent documentation
later. You could start with Bob's Z diagram and add the various label
names you used on your wires (specially if you used abbreviations),
along with wire gauge, color, etc. Also, be sure to add any connectors
with the pin number. Consider adding manufacturer & part numbers for
replacement purposes.
Those electrical diagrams you do now may be worth $$$ down the road.
Consider that I, and probably others, would not even consider buying a
plane without thorough documentation, unless it was at a "bargain"
price.

And what if one piece of equipment doesn't work as expected (things
sometimes happen), and you don't have a proper diagram to reflect on ?
I did a one page per system wire book, and took time to update it after
every change I made, and wiring and troubleshooting proved a breeze.
Troubleshooting ?
Yes I experienced troubles with off-the-shelf equipment (not my wiring),
and had to pinpoint the cause.
And when isolating a circuit during maintenance, I refer to my book,
because wiring was 4 years ago now, and things fade away in my mind.
So, I did, and I'm happy I did.

Gilles

Hi Erich,
You need a wiring diagram if only to keep notes of how things are and
after you're gone, the next owner needs some
hint of where you put things. I did a wiring diagram because there are
just too many things to remember only 3 years after
the fact. Nice to know what bundle of wires to look to when things go
down. Saved me on two occasions so far.
Modifications also require some idea of how you're loaded before the
fact, so if nothing else, do a simple one.
See link and modify them to suit you if you want.

"ground" is an un-quantified, un-qualified term term
when it comes to taming the noises emitted from an
accessory. Spent the whole day in the lab today "sniffing"
the noise performance of an airborne super-server that's
destined to share volume within an airplane with lots of
VERY sensitive spook receivers.
Anyone who pushes their noise containment duties off on
the installer by suggesting broad brush admonitions to
shield everything and keep stuff away from coaxes doesn't
have a clue . . .

Let's do some detective work and see if the real
leak can be identified before you start shot-gunning
with hopeful remedies.
What radio is being affected? Know that most of the
glass dial noise problems radiate from the opening
covered by the LCD. What does the "noise" sound like?
How is the noise affected by positioning various controls
of the victim radio?

I can see both sides of this issue and they are both right. Roll your

and I have added a few extras.
I am amazed though at the detail some folks put into their wire diagrams
and web sites. You people are absolutely gifted. Where do you find the
time to do all of that and build an airplane?
I don't think I will ever sell my airplane but if I did it seems these

| Subject: | Re: RF noise from EFIS |
Bob,
It may be hard to describe the noise, so I figured a video may help :) Here's
a 1-minute video of my sniffing around with a handheld scanner (squelch turned
down completely):
http://www.vitez.net/noise.wmv
You'll notice a few spots where there's no noise and you just hear regular radio
static.. Maybe ignore that weird noise when scanner is under the panel, as
I don't hear it like that in my panel radio.
The radio is Garmin SL-40. Not sure what you mean by positioning of controls..
Also, the radio (well, both SL-40 and handheld) does a great job of "killing" the
noise when it receives even a semi-decent transmission.. so this noise doesn't
actually affect reception, except for very, very weak ones (where the noise
can just about barely be heard in the background). However, it sounds horrible
(and loud) when there's no transmission and squelch is pulled. Again, it
never breaks the squelch... So, push the squelch and you'll probably never hear
it (or barely ever notice it's there).. but I'm looking for "perfection" here
:)
The radio has this mode where it shows the signal level, and for RF level it shows
around 18 when screens are off.. then jumps to about 40 when screens are turned
on.... Not sure what these numbers exactly mean or what units those are..
but there's definitely a difference. (this is with no transmissions being received).
Not sure if I mentioned this -- all these units are grounded on the firewall at
a common grounding block. Tried grounding locally on the panel (both radio and
screens as well as screens alone) and that didn't make any difference.
One thing I haven't tried yet is transmitting -- not sure if there's any affect
on clarity or strength of outgoing transmissions..
Any ideas are appreciated. Or am I getting worked up about nothing?
Thanks!

I drew a wiring diagram first because I wouldn't know how to wire it if
I didn't (basically a Z-11). Every signal has a name, every wire is
labeled. As one who has successfully used automotive wiring diagrams
(and other schematics), I'm sure the diagram will save trouble shooting
time down the road. It will influence a future buyer IF the guy is like
me. A lot of us builders are nerd-geek-techies who think this stuff is

None . . . but keep in mind that the "too hot to touch" contactors
have been used for about 70 years with good return on investment.
The "solid state" units have circuitry that drops coil current from
an initial, full power pull-in current to some nominal holding
current after a second or so. Problem with some devices is that
the duty-cycle power controller generates noise in some systems.
Further, it's unknown whether the circuitry as-supplied would
live happily in known (DO-160) world of stresses. I'm not suggesting
that it won't . . . just don't know.
The continuous duty contactor dissipates about 10 watts. Sufficient
power to raise the surface temperature to about 170F in a room
temperature environment. See:

This 'seems' hot but all of the materials used to fabricate
the contactor are rated at 150C or better. It's no big deal
in the grand scheme of things and it's hard to beat the price.

You just can't resist a dig at Greg can you?
Now I know why so many others think you are an asshole.
Do not archive.

I've started a Blog of my testing activities around the Vertical Power
VP-200 Duo going into my Lancair Legacy.
Feel free to check in from time to time. If you have an RSS reader, there
is both an RSS and an ATOM version of the blog.
http://legacyair.blogspot.com
Short version
- Dual buss
- Dual Alt
- 24V
- EFIS panel
- VP-200 Duo
- MVP-50 Engine monitor
- utilizing the 4 channels of Overrides on the VP-200
- plus all the normal amazing features
- going into a Lancair Legacy FG with IO-550
Also includes a few "requested features" - being a real beta tester :)
- Automatic canopy seal
- Remote based, electronic Canopy lock
