--> AeroElectric-List message posted by: "Trampas" <tstern@nc.rr.com>
John,
I would recommend running both wires to the back of the switch. That is, do
not put a connection in a hidden place or somewhere in-line, as that if a
problem happens it is usually at a connection. Thus it is helpful to have
all connections accessible.
As far as connecting the two wires together it depends on your switch. For
example if you use fast-on connections for the switch I would crimp the two
wires in the same fast-on. I am not sure if this is an acceptable practice
or not. If the connection is a screw I would put an eyelet on each wire.

I am wiring my navigation lights. I have a single wire coming off the
bus thru a single pole switch. At some point this single wire has to
branch into a left and right . How do I make this connection?. I
thought that just using a butt splice to connect the one power wire to
two branch wires would work. Will it? Is there a better way?
I would prefer not to use a double pole switch but if that is the
"proper" way, I will do it.
I would appreciate any help.

Just run the two wires to your switch and crimp them together in the same terminal.
It's okay to crimp multiple wires into the same terminal provided the terminal
is sized correctly. Look at Bob's shop notes on his web site, I believe
he has an aticle about this.

Correct. See
http://www.aeroelectric.com/articles/multiplewires/multiplewires.html
There is no prohibition for putting multiple wires into a single PIDG terminal.
It's done all the time.

For some reason, I don't seem to be receiving all of the AeroElectric List
traffic. For example, the exchange below just came through but I don't see the
posting that started the thread. I just checked the archives and see a lot
of traffice on the list that did not come through to my cox.net email account.
The only thing I can think of is that cox.net has some kind of spam filter
running that are trashing some of my incoming traffic. I'll be changing my
matronics
list-server email to the account that resides on my website server. Since
I own that server, I know there are no spam filters . . . unfortunately,
I can begin to expect lots of spam on that account as soon as I begin to
publish a new e-mail address . . . hazards of playing in the real-world
sand box.
Anyhow, I wanted folks to know that I've not been ignoring them. If anyone
has a query from the past several weeks that I appeared to ignore, wait
a day or two until my AeroElectric-List return address changes to
rnuckolls@aeroelectric.com That should fix the communications problem

Bob,
Instead of having the list messages sent to your email, why not just log onto the

threads: not always reliably. You don't want to wade through spam, which is
running 80% on my system.

Bob -
I have what may be an irrational aversion to rosin-core solder.
I seem to get much better results with my red tin can of Lenk paste flux and
solid (thin) solder. Are you aware of any problems or incompatibilities
with common paste flux residue in aircraft?

Hi George,
There is a problem with paste flux in any electronic wiring. Its residue
is corrosive and in time will damage anything metallic it comes in
contact with. Because of this property it is especially risky to use it
in aircraft wiring. Rosin core is the preferred solder for use in
electronics.

Let's not get too generalized here. There are paste and liquid fluxes
out there that are perfectly fine for electronics. You just have to
make sure that the residues are not acidic or otherwise corrosive. I do
not know if your "Lenk" flux is in this category or not. There are also
flux cored solders that are not suitable for electronics.
Rosin-core solder is good for electronics applications, but should
really be cleaned off after soldering - alcohol, acetone, mek or any
reasonable solvent.
There are also plenty of flux cored solder that is not rosin-based and
is great for electronics. There are several types that offer cores of
water soluble flux, low residue flux or others that are specifically
designed for electronics applications - some designed to be cleaned
after soldering and some specifically designed to be left on after
soldering.
The key is to make sure whatever you use states specifically that it is
designed for electronics applications and is specifically non-corrosive.
In some cases, where what I want to solder is not readily solderable
with electronics fluxes, I even use acid based or other highly active
fluxes to solder something "electronic". The trick there is to be sure
to thoroughly clean the joint after soldering. YMMV

I have perhaps a dozen different soldering tools, three or
four forms of electronic tin/lead solder and one form of
silver solder. The only solder that needs additional/external
flux is the sliver solder. Haven't had a can of flux in the
shop since I gave up soldering small enclosures together from
galvanized roofing material . . . that was about 35 years ago.
Check out the Kester offerings at:
http://dkc3.digikey.com/PDF/T042/1170.pdf
63/37 Resin 44 is my favorite. I do have a spool of "285" but
never found a need for it.
If you can't do a good job with these solders as-is,
there's something wrong with your tools, materials
and/or technique.
If you really gotta use an external flux, make sure
it's 'elctronic stuff like those offered at:
http://www.digikey.com/scripts/DkSearch/dksus.dll?Criteria?Ref=222564&Site=US&Cat=32703202
. . . but I'd be very skeptical of any need for externally
applied flux. The only place I've ever seen bottled
flux at RAC is on rework stations where they have to
deal routinely with soldered joints that have been exposed
to the wild and woolly world of service in airplanes.
Next time I'm over in that building, I'll ask the folks if
they ever find the stuff useful. I've done plenty
of "rework" in soldered joints where off-the-spool, pre-fluxed
solder was entirely adequate to the task.

Nothing "wrong" with this as long as ALL wires in the circuit are properly
sized for the FUSE supplying the circuit. You mention R & L, so I assume you
are using tip lights with the rear-facing white lights for say, 10 amps total?
Use 18 ga. from switch, strip about 3/4" from the splice end, double it over
and stuff into a blue PDIG splice & crimp. Yank on it to make SURE it is
tightly crimped. Strip 1/4" from the two 18 ga. wires to the tip lights, stuff
into
splice, crimp & yank. The electrons from the switch will never get confused
when they arrive at the splice, the red ones will go left and the green ones
right...........
The white ones are filtered by the kadink muffler built into the receptacle
and are drawn aft by relative motion conditioned by coriolis effect on surface
tension of lens.
(Most of the above is relevant- discard all else! 8-)

I am thinking on using a Comant CI120 VOR/LOC/GS dual blade antenna on
my Thunder Mustang. These blade type antennas are normally mounted on
either side of a vertical stabilizer and then the signal from each side
is combined together into a single coax/signal which goes to your radio.
My question is, does it matter how for apart the two blades are as I am
thinking about locating one in each wing tip which are 25' apart? The
Thunder Mustang is nearly all carbon fiber, except the wing tips.
Thanks.

Bob, I found it helpful to put a touch of liquid flux on the ends of those
25 pin D-sub connectors prior to soldering AWG 22 wires in them. Seemed to
make them go together better. Otherwise I agree.
