Subject: | Re: RE: Gilcrhist Electric |
I ordered a coax stripper via their web site and it was delivered via US mail while
I was at Sun'N'Fun last week sometime. Delivery time and price was as expected.
Note that I did not use ebay, etc to purchase this, I went directly to
their web site
No phone number was provided on the invoice, but the address is:
PO Box 10605
Bozeman, MT 59719
The web site is http://www.gilchrist-electric.com
The web site shows phone number as 409-586-6507.

Subject: | Re: Music Inputs |
Dustin,
I used a D sub crimper similar to the one Stein sells on Hi Density D sub pins
and it worked fine. The hi density pins are .050 in diameter (where the crimp
takes place) while the standard pins are .075. But my crimper contracts to about
.025 diameter. So I tried a couple and found the wire is nicely crimped.
You do have to be careful to position the pin correctly in the crimper as they
are different lengths. But to do a few crimps, a standard d sub crimper seems
to work OK.

The PVC 90 degree fitting at Lowes Aviation Supply fits right on.
Light yellow stuff that is cheaper than schedule 40....cant remember the name.
1 inch of pipe to make a bib.
Heat gun to soften it up and lock it onto the KX155 back plane.
Now lets see, how am I going to obtain a field approval on that....

Hello Bruce, You wrote: "Can you point me to the catalog locations or

I will try -- first a little basic information. The 430W and the SL30 both
put out and receive multiple signals to and from the 106A. So you need two
devices.
One device is a relatively simple push to activate switch on the instrument
panel which shifts the pilot's navigation choice from one source (430W) to
the other (SL30) or vice versa. This device should also have a light
indication on it to show which choice has been made.
The other device is remotely activated, more complicated, and it consists of
many relays and contact points that when activated by device number one
shifts all of the many signal paths between the 430W, the SL30, and the
106A.
There are multiple manufacturers and sources for both device one and device
two so one can shop around for their preference and purchase sources.
Here is a source for device one:
http://www.gulf-coast-avionics.com/list.asp?search_type=2&search_text=NAT
Here are some sources for device two:
http://www.sandia.aero/?q=SR64
http://www.trast-aero.com/eng/catalog/view.php?ModelId=401
These two sources are not intended to give you "ready to buy" information,
but rather to show you what kinds of devices you are looking for and some
possible items to purchase. It will take some leg work on your part to
discover the best devices for your use and the best sources to purchase them
from.
Perhaps other members on the list (Stein Bruch?) can also provide some more
specific choices / recommendations and sources.

understand knowledge."
PS: I have some Excel spread sheets that I made up that show my equipment
and the rather complicated wiring interconnections. If you think that they
might be of use to you please email me direct and I will send them to you
as email attachments.

Hi OC,
I am new to the list and saw this today. I am planning the same equipment ,
i.e.,
a 430W, SL30, and 106A. I am not familiar with the items you mentioned
about
switching back and forth. Can you point me to the catalog locations or
suppliers
with the correct items numbers? I'm pretty weak on the electrical stuff
although I reading up on it now(Bob Nuckolls book). Thanks for your help.

Oh my my. This is why people make fun of tech geeks and nerds, ha-ha. Yes voltage,
current and EMF are all magically intertwined. Even the magic of the hall
effect sender puts out proportional volts to current. But you all are right, there
are coils in those mechanical gauges. However a digital meter will read directly
off a shunt? Huha? What? Doha! ha-ha.

Interesting . . . it seems that the same folks would also
make fun of neurosurgeons, master chefs and physicists.
Individuals who poke fun at the assemblage of simple-ideas
into useful inventions are themselves at-risk for not
enjoying the benefits that arise from understanding . . .
a kind of self imposed exile to ignorance that leaves
them dependent upon those who DO understand.
> Yes voltage, current and EMF are all magically intertwined.
Nothing magic about it. But the conditions under
which they interact are not consistent. For example,
just because there is voltage to be measured doesn't
automatically translate to a current flow. Similarly,
there are conditions where huge magnitudes of current
flow with zero impressed voltage.
>Even the magic of the hall effect sender puts out proportional
>volts to current.
Sort of . . . volts is proportional to the intensity
of a magnetic field. The magnetic field can come from
a variety of sources not the least of which is the
field surrounding a current carrying conductor.
>But you all are right, there are coils in those mechanical gauges.
>However a digital meter will read directly off a shunt? Huha? What?
>Doha! ha-ha.
Yes, the digital voltmeter takes advantage of the
voltage drop impressed across a shunt as a result
of current flow. The measurements obtained by this
method are independent of simple-ideas involving
magnetics.
>Bob your "VAM10_Interior_View link" is not working?
Yes, I corrected it in the posting that followed
a few minutes after the first. The working link

Subject: | 2 electrical questions - diode and intermittent failure |
The diode for the battery master, what are the specifications?
Twice now while flying my aircraft (over 100 hours with no problems), my
main power has flickered. Off and right back on. I just checked all the
wiring for the master, and the only thing I'm missing is the diode. Ground
was my obvious place to look, all OK, excellent ground for the master
switch.
My next choice is to change out the master solenoid. Any other ideas?
Rocket - dual alternator with single battery. Standard Z-13 wiring.
Thanks in advance,
Jeff

An intermittent battery master would not cause the
system to go down completely. In fact, it's possible
on some airplanes that an alternator will run reasonably
well without a battery . . . complete loss of the contactor
may not be immediately noticed.
If you're looking for loose wires, everything between
the bus and BOTH power sources (alternator and battery)
should be examined. Unless you soldered your terminals
on a good tug on the fat-wire terminals is in order.
I've seen wires installed with inadequate crimp tools
pull out of their respective terminals without a whole
lot of effort.
