Thanks, Matt. First, the engine uses one plug per cylinder. The two ignitions
come together in coil joiners (isolation modules). I'd considered the possibility
of a bad high tension lead, but sort of discounted that because the engine
runs great from either ignition with no drop at all with mag checks. Then
again, that's just my logic talking and it doesn't mean that it's not a high tension
lead. I've changed plugs with the same result. If I could figure out
what "might" be causing it, I could probably do a little wire sorting and find
the culprit, but I'm just not knowledgeable enough to get a clear picture in
my mind what is happening. Obviously, it's emanating from the left ignition circuit
because when I turn off power to it, the noise in my headset stops and
the interrogation light on the transponder goes out. I've already checked all
of the high tension leads with an ohm meter and none are significantly different
which leads me to believe the problem lies in the "placement" of my wiring
bundles somewhere. Am I making sense?
Thanks again,

On the TC side of aviation's house, all appliances considered
for use on airplanes is evaluated for its stand-alone
characteristics with respect to noise emissions, noise
vulnerabilities, temperature limits, etc. The goal is
to offer smooth integration of that device into an
airplane where the installer does not need to accommodate
a shortfall in performance.
I presume that you have two identical ignition systems
of which only one causes noise. I'm presuming further
that few (if any) other builders have experienced the
noise issues with these systems. This leads me to
suggest that there is something "different" about the
two systems installed on your airplane. It might be
fixed by a wire installation revision . . . but if so,
then perhaps theses systems have not been sufficiently
refined sufficiently for smooth integration into aircraft.
I mention all this because it offers a mode of investigation
that looks for differences between the two systems. One
generates an unacceptable level of noise while the other
does not. How are wires routed differently between the two?
You might try swapping components between the two systems
to see if the problem follows the swap. You can use the
12 lantern battery experiment to power each system up
independently from ship's power . . . although this is
a very long shot for a noise that the transponder sees.
The transponder has already been qualified to tolerate
a lot of conducted noise into ship's wiring . . . the
energy that upsets it now is probably coming through
the antenna. So, try disconnecting the transponder
antenna for a short test to see if it stops triggering
on the noise.
This is a game of clue. You've identified the source
of noise and victim to that noise. Now you need to
ferret out the propagation mode. Once that's identified,
the fix will be easy.

The e-bus alternate feed switch cannot be a single point
of e-bus failure since it's the second of two independent
feed paths to the e-bus. If the alternate feed path is
pre-flight tested and then "put away unless needed" then
probability of it being available as needed is very high.
This was the spirit and intent of the alternate feed path
philosophy re-enforced by the notion that it was a good
thing to shut battery contactors off during battery only
operations.

The only thing that happens when the alternator quits
is that bus voltage drops from a nominal 14.2 volts down
to about 12.6 volts. If you did NOTHING at this point in
time, you would be no worse off than if you were flying
a C-172 except that your options for load shedding
for battery only ops are more limited in the C-172.
If you were typical of C-172 drivers, you would have
no idea how long the battery would carry the minimum
loads you were able to achieve because not one C-172
driver in 1000 has any first hand knowledge of (1)
battery capacity and (2) how long his minimized loads
will run from that capacity.
If you did not have the alternate e-bus feeder
installed (replace the diode with an avionics
master switch) you MIGHT still have a leg up on a
C-172 driver in that you could conduct the experiments
to KNOW how much battery only endurance you had with
that particular architecture.
Now, having added the alternate feed path and the
diode that prevents mis-routing of energy, you
have an opportunity to craft a confident plan-b
for dealing with alternator failure. The plan-b
removes all loads not necessary for en route operation
of the airplane . . . which can be quite small.
This INCLUDES energies need to keep the battery
contactor closed. Once you are cleared to land
you can turn the battery master back ON and run
any number of additional goodies you wish. Whether
or not they continue to run to the parking spot
is immaterial to the outcome of the flight.
There is no compelling reason to fly with the alternate
feed path closed. Even if your ships voltmeter feeds
from the e-bus, it reads about .7v lower than
main bus . . . so what? That value becomes the
NORMAL operating point for the e-bus. The fact
that it does not represent main bus voltage is
of no consequence to you as a pilot in the operation
of the airplane.

One cheap "tester" to find the source of the noise, is an old Walkman or
equivalent radio(yeah, those things about 2 generations older than the
Ipod), tuned away from any station, on the AM band, preferably near the
top...1650 or thereabouts. Then just move it about taking all necessary
precautions with regard to the prop slice/dicer up front. Wherever the
noise peaks, is the location of the offender. I've found bad voltage
regulators that way, among other things. Just a resistance reading
doesn't prove a high tension lead isn't leaking noise, only proves
continuity.

Looks like these folks have resurrected an idea
that was explored and abandoned 33 years ago:
http://www.perfectswitch.com/mobipower110vmodule.htm
This product appears to capitalize on the ability
of the alternator to output voltage that is many
times nominal rated output.
http://aeroelectric.com/articles/When_is_110V_not_Over_Voltage.pdf
I note further that this same company offers
accessories fitted to modern alternators that
utilize the alternator's higher voltage output
abilities to accomplish certain welding
operations.
http://www.perfectswitch.com/alternators.htm
http://www.perfectswitch.com/mobiarc150.htm
http://www.perfectswitch.com/remotecontrolmodule.htm
No doubt, modern diodes are considerably more robust
that those we struggled with in 1975!
They are in CA and too early to talk to on phone
right now. I've e-mailed them for more information
on the high current relays.

Good point! I've still got some pocket transistor
radios around that have been used for that purpose
years ago. In my case, I was tracking down arcing
insulators on power poles. The directional qualities
of their "loopstick" antennas can be exploited to
deduce direction of a received signal (as described
in the 'Connection's chapter on antennas).
I've not had occasion to use one of these radios
in many years. I heard of a more modern utilization
in a class on RFI/EMC issues about 15 years ago. The
speaker told how he boxed a pocket radio up in an
RF tight, aluminum enclosure. He brought a coax
connector through the box and tied it to a "primary
of a transformer" wound around the radio. I think
it was 5 turns of 22awg wire. He also brought out
the headphone circuit through RFI filters.
The radio was turned ON, tuned to the high end
of the band, volume up to max and the box closed.
A short piece of coax could be fitted at the end
with either magnetic or electric field probes
http://aeroelectric.com/Pictures/Tools/RF_Antenna_Test_Tools/Sniffer_Probes.jpg
I built these probes for use on a very broadband
spectrum analyzer. Another name for a fancy
receiver.
This poor man's electronic "stethoscope" was useful
for "sniffing" about the airplane for the purpose
of pinpointing the exit location for a radiated
noise source. This also assumes that the noise
source is also broad band with components in the
audible range. In other words, a relatively clean,
RF energy or energy at very high frequencies would
not produce a signal that one would expect to hear
with this tool.
In the case before us, the repetition rate for
ignition system currents are very much in the audio
range and have a base-band component that is at
or below the broadcast band detection range of
the pocket radio.
This system would not be useful for finding
conducted noise sources where the offending signal
stays pretty much in the wiring. Once it's absolutely
confirmed that the transponder's antagonist is
radiated (coming in through the antenna) then
perhaps Kelly's suggestion offers a useful tool for
further investigation.

Bob,
What I was saying is that I use the "alternate feed switch" (labeled
"E-Buss") as the primary feed to the E-buss, sort of like an avionics
master, and that the diode on the master is now a backup and as such, I
need to make sure it hasn't failed leaving only one feed path available
to my essential equipment. I do test the feed path, but I don't put it
away until needed, as you say, because I feel having it on simplifies
the process of load shedding (including the contactor and alternator
field) in case of alternator failure (or ground ops). I chose this
method because I don't want to risk inflight re-booting of my EFIS and
autopilot by flipping switches in the wrong order. That I don't have to
do (admittedly easy) math with the .7 volt diode drop is gravy, not the
deciding factor.
It strikes me that, if one didn't mind having an extra switch, the diode
could be eliminated as well, leaving the E-Buss as a separate entity
from the main buss. The philosophy of having independent feed paths and
being able to simply shed unnecessary loads would still be served.

Rick:
Thank you for taking the time to respond to the discussion of the broken
tuning knob on the A200. That certainly is good news about the part
availability. Too often, misunderstandings, half-truths and false
information are repeated on the internet without question, to everyone's
detriment.
I will be contacting ICOM for a replacement part, and installing it myself,
and probably blogging the process.
I agree with your time estimate: about 10 minutes start to finish (1 hour
minimum charge) seems right, based on my experience. I am glad that ICOM
will make this part available to owner-pilot-builders who have the savvy to
effect this repair. Thanks for clearing that up. I own 4 different ICOM
amateur and aviation radios, and am happy with them all. Keep up the good
work!

Just got a data package from Perfect Switch on their
"Power-Gate" products. I've combined all the images and
files into a single .pdf at:
http://tinyurl.com/59faul
The information is fairly descriptive. The text of
an accompanying e-mail stated that these are, for
the moment, un-directional devices. This means that
effects of the parasitic diode in their large array
of Power FET devices will "backfeed" power to the source
should the votlage on the load side become high enough.
It also means that they're not ready to perform as a
battery contactor with equally low resistance connection
for electron flow both directions through the device.
Prices for the current offerings are given on page
5 of the file. Here we find that a relay suited for
carrying starter currents will set you back over
$300.
I'm told by my local Gigavac rep that a sample contactor
has been ordered for us to play with.

The diode was considered necessary and useful to eliminate
the potential for having both switches closed at the same time
and having the main bus take power through the e-bus alternate
feed path . . . a bonus of using the diode IS the automatic
switching of one feed path and elimination of the switch.
Of course, how you choose to modify the system and its
operation is a personal decision.

| Subject: | Transpo V1200 regulator |
Okay, I tried looking at some old posts to help me figure out how to wire a
regulator I have but I think it just confused me more..
I have a Transpo V1200 regulator for a high amp output Alternator aka:
http://www.aeroelectric.com/Mfgr_Data/Regulators/Transpo/V1200_Transpo.pdf
Question is what all connects to all the terminals listed?
The label just shows:
"I"
"A"
"S"
"F"
"Stator Output" my guess is leave disconnected maybe use for testing ?
"B-" my guess is ground here..
Can anybody find a manual on what goes where? Or more to the point how to
incorporate it into the Z diagrams ?
Thanks Jeff.

for new and old subscribers. Understanding the AeroElectric-List policies will
minimize problems for the Administrator, and will help keep the AeroElectric-List
running smoothly for all of us.
******************************************
*** Quick Start Guide to List Features ***
******************************************
There are many features available on the Matronics Email Lists and each
one is described in detailed below. However, using the List Navigator
you can quickly access the complete set of features available for this
List. The List Navigator can be found at the following URL:
http://www.matronics.com/Navigator?AeroElectric-List
****************************************
*** How to Subscribe and Unsubscribe ***
****************************************
Simply go to the Web Page shown below and enter your email address and
select the List(s) that you wish to subscribe or unsubscribed from. You
may also use the handy "Find" function to determine the exact syntax of
your email address as it is subscribed to the List. Please see the
complete instructions at the top of the Web Page for more information.
The Subscribe/Unsubscribe web page is:
http://www.matronics.com/subscribe
Note that you will receive TWO conformation emails regarding your subsciption
process. The first verifies that your subscription/unsubsciption request
was received, and the second confirms that the process has been completed.
You should receive the first email within a few minutes of your request.
The second conformation will arrive in less than 24 hours. You cannot post
until you receive the second conformation email message.
*****************************
*** How to Post a Message ***
*****************************
Send an email message to:
aeroelectric-list@matronics.com
Your message will be redistributed to everyone currently subscribed
to the List.
*****************************************************
*** SPAM Fighter - You Must be Subscribed to Post ***
*****************************************************
When a new post is received by the system, the From: line of the message
is checked and compared against the current subscription list. If the
email address is found, the message is passed on to the List Processor.
If the email address isn't found in the current list of subscribers, it
is dumped. This serves to very effectively thwart 99% of the SPAM that
gets posted to the Lists.
Remember, however, that the syntax of your email address is very important
with regard to the configuration of your email application such as Outlook
or Eudora. For example, the following two email addresses may be
functionally equivalent, but only one would pass the Matronics Email SPAM
test depending on which was syntax was subscribed to the given List:
smith@machine.domain.com
smith@domain.com
Either email address syntax is alright, just be sure that you configure
your email application to match *exactly* the address you've subscibed to
the List.
**************************************
*** Enclosure Support on the Lists ***
**************************************
Limited posting of enclosures such as pictures, documents, and spreadsheets
is supported on the Lists. There are a number of restrictions, and these
are detailed below. Please abide by the rules put forth regarding the
content of enclosures.
These are some of the features and limits of enclosures on the Matronics
Lists:
1) Enclosures will only be posted to the Real Time version of the Lists.
2) Enclosures will NOT be included in the Daily Digest version of the Lists.
3) Enclosures WILL BE forwarded on to the BBS Forum Web site.
4) Enclosures will NOT be appended to the Archives.
5) Enclosures will NOT be available in the List Browse feature.
6) Only the following file types and extensions will be allowed:
bmp doc dwg dxf gif jpg pdf png txt xls
All other enclosures types will be rejected and email returned to
sender. The enclosure types listed above are relatively safe from
a virus standpoint and don't pose a particularly large security risk.
7) !! All incoming enclosures will be scanned for viruses prior to posting
to the List. This is done in real time and will not slow down
the process of posting the message !!
Here are some rules for posting enclosures. Failure to abide by these rules
could result in the removal of a subscriber's email address from the Lists.
1) Pay attention to what you are posting!! Make sure that the files
you are enclosing aren't HUGE (greater that 1MB). Remember that there
are still people checking they're email via dial up modem. If you post
30MB worth of pictures, you are placing an unnecessary burden on these
folks and the rest of us, for that matter.
2) SCALE YOUR PICTURES DOWN!!! I don't want to see huge 3000 x 2000
pictures getting posted that are 3 or 4MB each. This is just
unacceptable. Use a program such as Photoshop to scale the picture
down to something on the order of 800 x 600 and try to keep the
file size to less-than 200KB, preferably much less.
Microsoft has a really awesome utility available for free that allows
you to Right-Click on a picture in Explorer and automatically
scale it down and resave it. This is a great utility - get it, use it!
http://www.microsoft.com/windowsxp/downloads/powertoys/xppowertoys.mspx
Look for the link "Image Resizer"
3) !! This would seem to go without saying, but I'll say it anyway. Do not
post anything that would be considered offensive by your grandmother.
And you know what I'm saying; I don't want to see anything even
questionable. !!
4) REMEMBER THIS: If you post a 1MB enclosure to a List with 1000 members
subscribed, your 1MB enclosure must be resent 1000 times amounting
to 1MB X 1000 = 1 Gigabyte of network traffic!! BE CAREFUL and
BE COURTEOUS!
Also see the section below on the Matronics Photo and File Share where
you can have your files and photos posted on the Matronics web server
for long time viewing and availability.
*******************
*** Digest Mode ***
*******************
Each day, starting at 12 midnight PST US, a new 'digest' will be started.
This digest will contain the same information that is currently appended
to the archive file. It has all of the headers except for the "From:"
and "Subject:" lines removed, and includes a message separator consisting
of a line of underscores.
Each day at 23:55 PST US, the day's messages as described above will be
combined and sent as a single message to everyone on the digest email list.
To subscribe to the digest list, use the same subscription web form
described above, and just select the Digest version of the List.
http://www.matronics.com/subscribe
Note that you *can* be subscribed to both the realtime and digest versions
of the List at the same time. This is perfectly acceptable.
Now some caveats:
* Messages sent to "aeroelectric-list-digest" will be forwarded to the standard
email list. In other words, you cannot post messages only to the
digest List.
* If you are subscribed to both the regular List and the digest List, you
will receive the realtime postings as well as the digest at the end of
the day.
* If you reply to the digest email, your message will be forwarded to the
normal list associated with the digest. Important Note: Please change
the subject line to reflect the topic of your response! Also, please
*do not include all or most of the digest in your reply*.
****************************
*** List Digest Browser ***
****************************
An archive of all the List Digests can be found online in either plain text
or HTML format. These archives contain the exact Digest that was posted to
the Digest email list on the given day. The Digest Archives can be found
at the following location:
http://www.matronics.com/digest
*****************************************
*** The "DO NOT ARCHIVE" Message Flag ***
*****************************************
At times, your message may concern something that is revelent only to a very
small number of persons or to a limited area, and you may not wish to archive
it. In such a case, simply put the following phrase anywhere in the
message:
do not archive
Your message will not be appended to the archive, but will be sent to List
email distribution as normal.
**********************************************
***** READ THIS - Automatic Unsubscribes *****
**********************************************
Note that if your email address begins to cause problems such as bounced
email, mailbox is filled, or any other errors, your address will be promptly
removed from the List. If you discover that you are no longer receiving
messages from the AeroElectric-List, go to the following Web page, and look
for your email address and a possible reason for your removal.
The Matronics Email List uses utility called the "Email Weasel" that
automatically looks though the day's bounced email for addresses that
caused problems due to common things like "user is unknown", "mailbox
full", etc. If the Email Weasel removes your email address from the
Lists you will find record of it at the following URL:
http://www.matronics.com/unsubscribed
If the problem listed on the web site above has been resolved, please feel
free to resubscribe to the Lists of your choice.

*** Realtime Web Email List Browsing ***
****************************************
Recent messages posted to the AeroElectric-List are also made available on
the Web for realtime browsing. Seven days worth of back postings are
available with this feature. The messages can be sorted by Subject,
Author, Date, or Message Thread. The Realtime List Browser indexes are
updated twice per hour at xx:15 and xx:45. You can also reply to a message

Browser Interface in view-mode.

*******************************************
*** Web Forums Bulletin Board Interface ***
*******************************************
A phpBB BBS web Forums front end is available for all AeroElectric-List content.
content. The Forums contain all of the same content available via the email
distribution and found on the various archive viewing formats such as the
List Browse, etc. Any posts on the web Forums will be cross posted to the
respective email List, and posts to the Email List will be cross posted to
the web Forums.
You may view all List content on the Forums without any special login.
If you wish to post a message via the Web Forum interface, however, you
will need to Register. This is a simple process that takes only a few
minutes. A link to the Registration page can be found at the top of the
main web Forums page. Note that registering on the Forum web site also
enables you to send email posts to the Lists as well. You will also need to
Subscribe to the respective Email List as described above to receive the
Email Distribution of the List, however.

*********************************
*** Matronics Email List Wiki ***
*********************************
In an attempt to make it easy to store and find structured and often accessed
information, Matronics has installed a Wiki at:
http://wiki.matronics.com
The Wiki allows individuals to create web pages to contain useful information
for other users of the mailing lists and web site. Unlike an ordinary web page
where the content needs to be submitted to Matronics for inclusion, the Wiki
permits the users to construct their own pages and have them visible immediately.
While constructing pages for the Wiki is not difficult, some may not be
comfortable building pages. In that case, simply prepare the text and any
images and email it to:
wiki-support@matronics.com
One of the volunteers on that list will take your submission and construct
a Wiki page for you.
Often someone produces a particularly useful posting in email one one of the
Lists that would be of general interest. In that case Matronics may take that
post and convert it into a Wiki page.
*********************

*** List Support Contributions ***
**********************************
The Matronics Lists are run *completely* through the support of it members.
You won't find any PopUpAds, flashing Banner ads, or any other form of
annoying commercialism on either the Email Messages or the List web pages
associated with the Matronics Email Lists. Every year during November
I run a low-key, low-pressure "Fund Raiser" where, throughout the month,
I ask List members to make a Contribution in any amount with which they
are comfortable.
I will often offer free gifts with certain contribution levels during the
Fund Raiser to increase the participation. The gifts are usually donated
by companies that are themselves List members.
Your Contributions go directly to supporting the operation of the Lists
including the high-speed, business-class Internet connection, server
system hardware and software upgrades, and to partially offset the many
many hours I spend running, maintaining, upgrading, and developing the
variety of services found here.
Generally Contributions range from $20 to $100 and are completely voluntary
and non-compulsory. I ask only that if person enjoys the Lists and obtains
value from them, that they make a Contribution of equal magnitude.
Contributions are accepted throughout the year, and if you've just
subscribed, feel free to make a Contribution when you've settled in.
The website for making SSL Secure Contributions is listed below. There are
a variety of payment methods including Visa and MasterCard, PayPal, and
sending a personal check.
If you enjoy and value the List, won't you make a Contribution today to
support its continued operation?

AeroElectric-List Usage Guidelines
******************************************************************************
The following details the official Usage Guidelines for the AeroElectric-List.
You are encouraged to read it carefully, and to abide by the rules therein.
Failure to use the AeroElectric-List in the manner described below may result
in the removal of the subscribers from the List.
AeroElectric-List Policy Statement
The purpose of the AeroElectric-List is to provide a forum of discussion for
things related to this particular discussion group. The List's goals
are to serve as an information resource to its members; to deliver
high-quality content; to provide moral support; to foster camaraderie
among its members; and to support safe operation. Reaching these goals
requires the participation and cooperation of each and every member of
the List. To this end, the following guidelines have been established:
- Please keep all posts related to the List at some level. Do not submit
posts concerning computer viruses, urban legends, random humor, long
lost buddies' phone numbers, etc. etc.
- THINK carefully before you write. Ask yourself if your post will be
relevant to everyone. If you have to wonder about that, DON'T send it.
- Remember that your post will be included for posterity in an archive
that is growing in size at an extraordinary rate. Try to be concise and
terse in your posts. Avoid overly wordy and lengthy posts and
responses.
- Keep your signature brief. Please include your name, email address,
aircraft type/tail number, and geographic location. A short line
about where you are in the building process is also nice. Avoid
bulky signatures with character graphics; they consume unnecessary
space in the archive.
- DON'T post requests to the List for information when that info is
easily obtainable from other widely available sources. Consult the
web page or FAQ first.
- If you want to respond to a post, DO keep the "Subject:" line of
your response the same as that of the original post. This makes it
easy to find threads in the archive.
- When responding, NEVER quote the *entire* original post in your
response. DO use lines from the original post to help "tune in" the
reader to the topic at hand, but be selective. The impact that
quoting the entire original post has on the size of the archive
can not be overstated!
- When the poster asks you to respond to him/her personally, DO NOT
then go ahead and reply to the List. Be aware that clicking the
"reply" button on your mail package does not necessarily send your
response to the original poster. You might have to actively address
your response with the original poster's email address.
- DO NOT use the List to respond to a post unless you have something
to add that is relevant and has a broad appeal. "Way to go!", "I
agree", and "Congratulations" are all responses that are better sent
to the original poster directly, rather than to the List at large.
- When responding to others' posts, avoid the feeling that you need to
comment on every last point in their posts, unless you can truly
contribute something valuable.
- Feel free to disagree with other viewpoints, BUT keep your tone
polite and respectful. Don't make snide comments, personally attack
other listers, or take the moral high ground on an obviously
controversial issue. This will only cause a pointless debate that
will hurt feelings, waste bandwidth and resolve nothing.
- Occassional posts by vendors or individuals who are regularyly
subscribed to a given List are considered acceptable. Posts by
List members promoting their respective products or items for sale
should be of a friendly, informal nature, and should not resemble
a typical SPAM message. The List isn't about commercialism, but
is about sharing information and knowledge. This applies to
everyone, including those who provide products to the entire
community. Informal presentation and moderation should be the
operatives with respect to advertising on the Lists.
