I have one convenient place to run wires thru the baggage area, and I will
be running two coax for xpndr and com antennas, a whelen tail strobe cable
(with single central strobe unit - ie, high voltage run), aux battery power
for second electronic ignition, MAC electric rudder and elevator trim cables
and flap motor controller power and switch. Are there any recommended
separation rules of thumb? I could separate two bundles by about 4" or
three separated by about an inch. I imagine the strobe, com and xpndr are
the noise generators and should be separate from the rest, but should also
be separate from each other. Could I get away with bundling any of these
together?
Thanks,

I designed superflexible abrasion resistant special cables for surgical use
for years. My favorite was a urethane sheathed litz-wound silver-plated
bronze wire with a Kevlar yarn reinforcement ESG cable. Yikes!
But commercially, "Superflexible" means Mogami (sold in the US by Marshall
Electronics) used by the audio/video industry. It finds its way into top-end
headphone cables and microphone cables.
For a cheap solution, steal some good quality CD headphones. Cut the cords
off for you airplane and give the headphones back to your teenager for Xmas.
Say they're the new "cordless" type.

Bob
I bought the firewall foward package from lancair. I can make the system
into the Z14 system with some modifications. Thats what I want to do. Most
of the building blocks are there to do this. I am still in the process of
doing composite work and have not spent that much time on the electrical
system yet, but I do need to make the electrical harness for the individual
systems. I want to finish the harness, anntenna wires and battery cables and
install them before I close the top. I am going to make a bundle for the
system wires, one for the antennas and one for the battery cables. I plan to
have a connector for the systems at the panel. Idividual bulkhead connectors
for the antenna wires. The battery cables to the studs on the firewall.
After I get the top on I plan to go on to the panel wiring. I have been
putting of the panel wiring to the end in order to see if any new toys hit
the market. So many choices.
Sorry about the rambling, back to the original question. I would like to do
the Z14 system. Do I need to run an extra ground wire all the way to the
back of the plane or can I tie the battery grounds together and run one
ground cable up to the front.
Thanks

I've often encouraged folks to acquire and become familiar
with catalogs of materials and supplies . . . in addition
to helping locate sources for various materials, they are
often powerful educational tools.
I've run across a .pdf file catalog for wire and wiring
supplies that includes a wealth of technical information
and I recommend you add this to your library. For a short
time, I've posted it at:
http://216.55.140.222/temp/wirecatalog.pdf
Folks running across this post in the archives at some later
date may access the on-line version of the catalog at
http://www.std-wire.com/ViewCat.htm
the on-line version has some advantages in that the
table of contents is hyper-linked to various subjects
within the rather voluminous catalog (260 pages,
7 Mbtes). If you download the .pdf file, the hyper-links
don't work but Acrobat's text search feature works
nicely and lets you find a keyword or part number anywhere
in the catalog.

Separation "rules" are generally useful only when the folks
who built the systems didn't do their homework for interference
emissions and susceptibility. By-and-large, there are few if
any concerns for wire bundle separation in light aircraft with
the following exception. I wouldn't run avionics bundles in
with wires carrying airframe systems power and control.
This is not difficult to do because 99% of avionics signal
wires are clustered around panel mounted equipment and are
easy to route separately from wires that come in from around
the airframe to the switch panel.

Gee, this is one I can answer since I am building my panel and actually have
some of these around. You should be safe with 3.25" if you measure
accurately. I measured between 3.231 and 3.252". They would also tolerate a
few thous trimmed off the edges. They are basically the same size as the
three instrument frames I currently have, 3-1/4" square (no AI or DG, but
would think most new would be the same - the UMA units for these are the same
size regardless). You might leave an extra .010-.020" for the vertical
spacing as the pigtail exits on one side (it is flat, only .009" thick).

Talked to John on phone today . . . I've been trying to catch
up on pending items of e-mail and orders. I'm temporarily
out of books but have some more on order from printer. Had
a devil of a time getting the documents published for the
parachute system . . . the computer kept barfing and throwing
away lots of work pasting the drawings into MSWord . . .
Bought a newer bare bones machine and spent the better part
of two days spare time getting it loaded with software
and configured. Tried editing the huge MSWord document
that choked the other machine and things seem to be stable.
Sure glad I started keeping all work product on hard drive
separate from the boot drive where all software resides.
It's really easy to keep the work product backed up over
the network . . . and easy to move the whole nine yards from
an old to a new computer.
Anywho, I'm starting to wade into the backlog. Sorry to
be so un-touchable for the past two weeks.

Haven't heard anything from Lancair as to how they would
like to proceed. I'll rattle their cage again. I've got
a couple of ideas. Will see which is most attractive to
them.

Generally no. Automotive alternators worth considering for
aircraft have built in regulators. You can either modify
one of these like B&C does to make them into externally
regulated machines or use the built in regulator as shown
in figure Z-24.

Where are you getting contradictions? Diagrams in Appendix Z are consistent.
I recommend a fusible link off a fuse block to a 5A breaker on the panel
-OR-
if acres-of-breakers is your cup of tea, then a 5A breaker off the bus
is indicated. I would not recommend a fuse to protect the field circuit
UNLESS
you were using an old-fashion OV relay that is truly a relay that simply
breaks the field circuit to shut down an alternator.
While rare, it DOES happen that ov systems (relay or crowbar) get nuisance
tripped. If you have a crowbar system, a re-setable breaker is indicated.

The only form of battery condition that can make
the system unstable to the degree that an ov protection
system trips is an OPEN battery. If it started
your engine then this possibility is eliminated.
If you get spikes in the ammeter the same time the ov trips,
then there is a problem with the regulator -OR- wiring that
hooks up the regulator/field wiring. I had a similar problem
with an airplane that was getting transient shorts between the
field and b-leads attached to the alternator. There have
been situations where pieces came loose inside an alternator
and allowed it to go into runaway mode but this is VERY rare.
I think Dave S. commented on this and I agree that the problem
seems most likely to reside in your regulator.

Chrissi,
If you haven't already, take a look at the FiberLite bezels. They will send
you a bare bezel to play with for about $10. Check 'em out at
http://sptpanel.com/. Their reverse engraved panel overlays are fantastic as
well.
