Hello Keith, Here is how I looked at your jpg attachment of the Blown fuse
annunciator circuit:
1) Note the subject matter of the email posting that has the attachment you
desire to see.
2) Go to the aeroelectric list navigator site by clicking on the URL at the
end of each list digest:
http://www.matronics.com/Navigator/?AeroElectric-List
3) Click on the BBS forums URL:
http://forums.matronics.com/
4) Scroll down to the appropriate list -- in this case aeroelectric, and
click on it:
http://forums.matronics.com/viewforum.php?f=3&sid=b2280214d4829c9f10f3ad00ea4de9d3
5) Scroll further down to the subject postings. If one of the series of
postings on the subject contains an attachment the subject listing should
have a little paper clip icon indicating that some where in the series of
postings on that subject there is an attachment:
http://forums.matronics.com/viewtopic.php?t=71859
6) Scroll further down to the end of the posting with the attachment and
voila! there should be the attachment in all its visible glory.
Please let me know how you make out.

PS: There is sort of a gotcha. I posted a jpg picture on the KIS list (see
here I hope):

and the picture posted just fine except that its layout on the forum was so
huge such that one had to scroll all over the place to find the area of
interest.

Rather than use a resistor, I would cut the
strip in half, as the manufacturer suggests, and put the 2 strips in
series.
This way you need no resistor and you can run it on 24V. See attached
sketch.

This is something of a conundrum when posting pictures.
Even the most inexpensive of modern cameras are capable
of imaging and recording in great detail with some pictures
being as much as 3000 pixels wide.

This is something of a conundrum in that not
everyone's computer will handle viewing of a
downloaded image exactly the same way. It depends
on your default image viewing application in
addition to defaults set up within that application.
I don't even remember what the defaults are on
this computer, I set them up years ago and promptly
ignored/forgot them.
Even the inexpensive cameras are capable of
imaging and recording in great detail with
pictures upwards of 3000 pixels in width. Bob's
uploaded image was 2,304px 1,728 pixels.
The first blush presentation on my computer did
indeed produce an image that ran off the screen
in both height and width.
But in my case, a right-click on the image produced
a pull-down where "view image" is an option. Selecting
that option zoomed out on the image so that it
fit the screen. You can also right-click images
and tell your computer to save them to hard drive.
After they reside on your own hardware, you can
open them with any other application for viewing,
resizing, editing, etc.
Unless I'm posting an image that contains detail
best viewed in the camera's raw output, I try
to re-scale the pictures to 1024 pixels wide so
that they fit the native settings for most folks
computers . . . but even that's not a 100% sure
thing for everyone's viewing convenience.
By the way, adding those nifty air flow control
features at the wing roots is reminiscent of
an effort to improve the handling qualities of
a Cessna 303 Clipper/Crusader.
http://www.airliners.net/aircraft-data/stats.main?id=155
http://en.wikipedia.org/wiki/Cessna_303
I recall a presentation given by a Cessna test pilot
at some dinner-with-a-tech-talk. He showed us video
of the 303 flying on the single critical engine at
some breath-taking low speed doing maneuvers that
approached aileron-rolls.
This became possible only after much study
and some tweaking that included airflow fences at
the wing roots. This insured maintenance of pitch
control under conditions that no pilot with a
family would routinely venture into. Except of
course, THAT test pilot!
Neat stuff that aerodynamics.

Subject: | Welding Cable for Battery Leads. |
I see other post that approves the use of welding cable for the main battery feeds
to the contractor and starter etc. My question is if we are being careful
to use Tefzel for all our wire to reduce the chance of smoke in the cockpit why
would you change that for the main power feeds? Is it easier to work with
than 4 ga Tefzel, that is more flexible? I am planning on using the welding cable
because it is local and cheaper. But have that concern I would like to address
on the safety issue.

Subject: | Re: Picture format for posting |
Oversized pics are a constant issue and most people just delete them
since it is so hard to view them. For PC users Microsoft has the
tool for resizing a picture. Find the download on the right .
http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx
To use the tool click on properties of the pic and choose small or
medium and get an new file for posting.
It would be nice if everyone used the tool.

Why not 4AWG welding cable which is more flexible
yet?
I am planning on using the welding cable because it is local and
cheaper. But have that concern I would like to address on the safety issue.
Just for grins, take a piece of 22AWG Tefzel wire about
2 feet long, strip both ends about 1/2", and grab
the bared ends in a two pairs of pliers. Now stob
the pliers to the terminals of your car battery.
Observe whether or not Tefzel wire "does not
smoke". Take a little whiff of the gray-stuff
wafting away in the air . . . is it something
to which one might wish to become addicted?
My point is that there is no such thing as
a wire insulation that (1) doesn't smoke
or (2) produces a smoke that does not produce
severe discomfort in the cockpit.
Of course those-who-know-more-about-airplanes-
than-we-do are ever more willing to "approve"
or "disapprove" our selection of materials all
in the name of the "greater good".
Bottom line is that safety comes from not having
the wire smoke in the first place which has to
do more with architecture and materials. I.e.
installation of fuses and breakers. And
installation techniques, I.e, don't let wires
rub on sharp sheet metal edges.
Beyond this, insulation selection is driven
by considerations for durability in service.
Welding cable is designed to lay on gravel
roads and be run over by dump trucks dripping
oil. They'll be just fine under the floorboards
of your flying fliver.
Risk is managed more by what YOU DO than by
what YOU BUY.

When building an airplane, there never seems to be enough

over the years:

They're built of cheap materials and not painted
to minimize acquisition $time$. They go together
in about 30 minutes for under $20. Has the same
footprint as a standard 6-foot folding table but
holds 50% more stuff. Knocks down to store. I use
them for garage sales too. I sell the table at
the sale for $30 to avoid storing them. They've
got a lot of utility when temporary table/shelf

And, if I may piggy back on this, the fact that it is more flexible
means that a less than perfect installation is less likely to cause
fatigued connections (or even fatigued wire).

Absolutely! The wire is DESIGNED for flexibility being
crafted from copper cat hair . . .
http://aeroelectric.com/Pictures/Wire/4AWG_Welding_Cable_1.jpg
. . . which means that it is fundamentally less suited
to stressing terminals by virtue of it's role as
a Class 2 lever. It's difficult to apply a force by
means of a soggy noodle.
Some of the earliest experiences with SVLA battery failure
manifested as a fracturing of the lead terminal-posts
just at the top of the case seal . . .
Emacs!
Root cause turned out to be 2AWG Tefzel battery jumpers
transmitting considerable stress to the posts under vibration.
Converting to welding cable jumpers fixed the problem.
However, this doesn't negate the need for support immediately
adjacent to crimped or soldered joints where the
wire transitions from very flexible to very inflexible.
Thanks for reminding me Charlie.

Subject: | Rotax 914 internal generator |
Hi group
I am using Eris Jones Linear Over-Voltage Protector to control my Rotax 914 internal
generator through a 75 amp automotive relay.
At moment I have relay on my schematic downstream of the Ducati regulator. If regulator
fails and there is in fact a runaway over volt event, true the L OVP
device will disconnect it from my electrical system, but the generator will still
be outputting.
Do you think I would be better off moving the relay that is controlled by the L
OVP to be in series with one of the generators yellow output wires?
Here is my schematic with relay downstream of Ducati regulator:

Bill Bradbury,
Thanks for the heads-up re Avery sticky back sheets. I'm doing essentially the
same thing through a graphics shop, but if that ends up going in the trash, then
I'll try Avery next. Ink jet isn't as color fast as laser toner, but with a
couple of clear coats, the effects of UV should be somewhat diminished. But the
color fade was a concern and solvent based inks are more color fast than water
based (ink jet) ink, so for $10 I gave it a shot.
