Subject: | Ray Allen Pushbutton Wiring Question |
The wire supplied with the Ray Allen microphone PTT grip is very small. I
would say it is #28 or #30. What is a good butt-splice to use for this
application.

Subject: | shielded comm radio question |
Hello group=2C
Can someone with avionics wiring experience advise me whether or not I ne
ed
shielded wire for my Icom A200 power in and out. I will have a strobe ligh
t system. I also have
a King transponder.
I have an ample supply 16AWG shielded tefzel. I've wired the +12V & gnd
for the KT 76
with the shielded stuff so far. (maybe I didn't need to. ???)
Should I use the shieded stuff for the Icom +12v & the ground=2C or the f
lash tubes supply=2C
or both? The Icom is the mobile vehicle style =2C with the CB radio type t
ray (could be the same
tray the airplane version uses). The factory wiring plug for the A200M use
s just ordinary auto
type wire. Surely they know lots of line vehicles have strobes=2C too. Ri
ght??
I'm just not clear when shielded wire is really neccessary=2C or where it
ought to be used.
Thanks=2C MIke Welch

Those that are using Vans tachometers, have you had any problem with them.
Mine after 223 hours is intermittent. That is it will go to zero and after a
brief time go back to working normally.
Is this a transducer problem or gauge. All wires have been checked.
Thanks,
Ed Clegg

For wire that small a butt splice would not be apprpriate. Instead,
soldering the wires together covered by heat shrink might be a better
alternative.

My Vans transducer is brand new and I can already tell it's a piece of
junk. When I spin it by hand it gets stuck in the grove. Your cable is
either broken inside or it's about too. I'll be really surprised if I
get 233 hours out of it. I've read from some that the backside of the
tip can be filed down so it doesn't catch so much.
Personally, if there is a better option, I'm all ears.

You could also use solder type D-sub connectors with heat shrink.
I used the High Density 3 row D-sub connectors from Radio Shack modified to fit
inside my stick.

Do these splices require a special crimping tool? At what
price?

Suggest you review chapters on noise in the
'Connection. Shielding is a hedge against a
particular form of coupling (electro-static)
between a potential antagonist and a potential
victim. Unless specifically called out in the
manufacturer's installation instructions, don't
bother.
Shielding of power lines is never useful. If
manufacturer's data does show shielded wire
on power leads, I'd like to know about it.

But Stan, there have been gazillions of right
angle adapters produced and no doubt successfully
used in as many situations. The fact that you
suffered one instance of a failed installation
would be worthy of a failure analysis. There
is probably a logical cause for the effect that
has nothing to do with whether any particular
combination of connectors was installed.

???? Dsub pins are designed for 20AWG max. Suggest you carry
the four ground pins all the way on 20AWG. Use two for one
radio, two for the other..

Thanks for the reply re: the shielded cable. I'll do the review you ment
ioned. No=2C I didn't
see anyone's recommending the shielded wires. I was just trying to avoid a
potential problem=2C
since wiring changes at this stage is simple compared to doing a repair lat
er.
___________________________________________________________________________

Now=2C for this post=3B for the last hour and a half I've been scouring
the internet looking for the
Garmin 296 pinout. The best I could come up with is the list of the 9 item
s in the connector=2C but
nothing so far that identifies which one is which.
Could someone direct me to a link of the Garmin GPSMAP 296 pinout. I hav
e the bare cable
and am intending on hard wiring the unit for my Air Gizmo Panel Dock?
Thanks again=2C Bob=2C and thanks for anyone that can find the 296's pino

Yep, that looks like the ticket. It is in fact already configured for the
task at hand. The only reservations I'd have are the cost and size. In my
cursory explorations they have both been rather large, although neither
seem to be listed for this particular unit.

Whupps- looks like I hit send a smidge too soon... the size is listed on
another tab and would be entirely fine at 4-3/4"W x 6-3/8" L x 2"H. Were
it mounted in a recess behind a hinged piece of plex such that the plex
naturally fell over the switch to cover it, it would be protected from
accidental tool-induced shorts while it's position would still be visible.
Then about the only pilot-proofing issue would be avoiding plugging the
unit into a 12v system while configured for 24v.
