--> AeroElectric-List message posted by: "James E. Clark" <james@nextupventures.com>
Glacier
I was asked to go flying with a friend who is working on his CFI. He had
access to a Cessna 150 with a releatively new looking (non-King, non-Cessna
[ARC??]) Narco maybe radio.
When you power it up, it comes up with 121.5 set so you have to change and
toggle to what you want.
He mentioned a radio problem so I got my handheld and we checked the radio
on the ground. All seemed fine.
THE PROBLEM:
Since he wanted me to fly I wanted to work the radios as well and when I
fired up the plane and did a "radio check", part of the first transmission
made it and nothing but carrier thereafter.
Several "tests" later showed that:
1. When the plane's engine was NOT running, the radio (transmit) worked
2. When the engine WAS running the radio (transmit) did NOT work
3. Bypassing the intercom and "plugging in direct" had not effect
4. Receive worked in all scenarios
THE QUESTION:
What could be going on here??
MY THEORIES:
1. The radio's "input" section is getting noise that is interferring with
the carrier modulation (but how???)
2. The alternator is REALLY generating some noise (but I don't hear a
"whine")
3. There is a really bad grounding problem somewhere (but it RECEIVES just
fine)
HELP:
What do you think could be the culprit??
THanks,
James

| Subject: | King 520 CDI GS Flag |
--> AeroElectric-List message posted by: Scott Derrick <scott@tnstaafl.net>
I just hooked up a King 520 CDI to my Garmin GNC300
Everything works as per the Garmin manual. However the 520 has a GS and
GS flag. I left the GS flag pins floating thinking it would retract
automatically but it doesn't.
I'm only using the Garmin to drive the 520 right now so I would like to
retract the GS flag when ever power is applied to the avionics stack.
I have two pins, GS+ and GS-, which pin do I pull to ground or common
and which do I pull up to 14 volts to get the flag to retract? Do I
need to put a resister in line to limit the current? If so does 10K
sound about right?

Have you tried changing the alternator pulley, or even the one on the
engine???
Should boost the output and might be a cheap fix.

<james@nextupventures.com>
Dick's posting has some very IMPORTANT data to make a note of.
<Output at lower RPM.>
I have found that our "35 amp" alternator (not B&C) *probably* does 15-17
amps at "lower than cruise" RPMs. So ... when approaching the airport in
late afternoon, if I turn on both landing lights, along with strobe and nav,
and announce my position, by the time I am on final (if not before), I have
a BIG RED "low voltage" light staring me in the face. I can literally see
the voltmeter easing toward the lower numbers.
So make sure that you get an alternator that really does put out the
amperage you need without you having to be turning, say 2500 RPM.

Bob,
I'm afraid the document is too large for your mail server to accept it :
'<bob.nuckolls@cox.net>: message size 9991494 exceeds size limit 5242880 of
server mx.east.cox.net[68.1.17.3]'
I'll try to place it in a public directory on one of our servers at work.
I'll keep you posted.
Regards,
Gilles

Gary, I may be interested in the GX60 if you want to sell it

try using nuckolls@aeroelectric.com
That's my server. I don't think we have any limit on it.

| Subject: | Windows viewable sketches (was Todd's Coolant Header |
Tank...)
--> AeroElectric-List message posted by: "David Carter" <dcarter@datarecall.net>
Todd ( and/or others on all 3 lists who know how to create "Windows viewable
sketches",
This is a "builder documentation" and "builder put out sketches for peer
review" question/issue.
Todd, I looked at your pictures and the color sketch of your coolant system,
a .jpg file.
Did you do the sketch free hand and scan it? Or, did you use some software
product to draw/sketch it?
With your .jpg file sketch opened and viewed by my Kodak "Imaging for
Windows", I studied the Help document and tried some things, to try to learn
how to "draw" - no luck. The drawing toolbar at bottom is greyed out.
- I notice at the very top of screen, it says, after the icon for the
Imaging viewer software: "Coolant flow system.jpg - Imaging [Read Only]"
- Why would it be "Read Only"? Is there a feature like in spreadsheets
which can be "locked" to prevent changing critical cells?
- Is my "bundled" software one of those damnable "lite" (less features)
versions of "real" software?
I have Intellicad, an Autocad clone, to create drawings with, but drawings
created that way require anyone wanting to view it to have a similar
software package, which many do not.
- So, I'm looking for a drawing tool other than Intellicad/Autocad that
can be viewed by anyone with Windows (and the typical viewers bundled with
it).

| Subject: | Oil press warning trouble. |
--> AeroElectric-List message posted by: "Sam Hoskins" <shoskins@globaleyes.net>
Bob, did I do something wrong, or did I get a bad oil pressure switch?
I wired my Hobbs and low oil press warning circuit exactly (I think) to your
drawing labeled; HOURMETER/OIL P WARN.
With the master on, there is no warning indicator.
My voltmeter says there is 12.5 V on the oil press switch terminal "S" and
about 11.5V on terminal "I".
I touched a temporary ground wire to terminal "S" and the light came on.
Verdict?
Does the switch need to operate a few times to "loosen up". It has never
had oil pressure applied to it.
Thanks.

Somebody help me - concerning the 3 drawings Bob gave links to at the bottom
of this: Are they a revision to a Z-diagram in AeroElectric Connection?
Or, are they something "custom made" just for one particular application? I
must have missed the original e-mail traffic and don't know what the first
part of the "thread" said.

David,
Thanks for the kind words about my web site. I hope you continue to find it useful.
Having initially figured out how to do a few simple things, I just edit the raw
html files with additions to the site. The tables are typically MS Excel spreadsheets
- Excel has an "export to html" function. The systems section, that
includes wiring diagrams, was created as an MS Powerpoint presentation set of
slides. Powerpoint has an "export to html" function that creates the pages on
the web site.
I've used the web site as my main method of documenting my work on the 6A, & I
continue to refer to it frequently.

These are a variation on a theme applicable to ANY of hte
Z-drawings where you have loads on the battery bus that require
protection at over 7A (5A if certified). Here I've shown
the use of mini-contactors or relays located right at the
battery bus tap to power high current loads for the engine's
electronic controlled ignition and fuel injection. Lower
current draw loads 7A and below can be comfortably carried
on long leads to the panel switches while higher current
loads benefit from a relay. The goal is to minimize the
length of an always-hot wire fused at greater than 7A for
crash safety.
