Thanks for the various responses to my posting, copy below. The consensus seem
to be a standard sized pulley and I will machine a replacement from alloy. Still
not sure about connections required. It would appear only one of the three
pins is connected, other than the main power lead. Does anyone know which one?
( the connector has three small pins in a straight line ), or is there a way
of testing. Thanks for your help.
Regards Neil Hederson

I think you have received the Garmin wiring manual. If not, let me know and
I can get that info to you.
I have a Velocity with the Garmin 430, Navaid, and the installed Porcine
coupler. The Garmin 430 outputs an RS232 data stream that is called
"Aviation - No Altitude" that can be read by the Porcine.
However, if you purchased your Navaid/Porcine prior to July this year, you
will need to call Porcine and get an updated chip. My original chip would
not read this data stream - but they do read the NEMA-183 data stream from
hand helds well.
My installation is working in the heading mode - but not course. I think it
is a matter of tuning and I haven't gotten that sorted out yet. There are 6
heading gain settings and 4 course mode settings, which are related.

| Mike,
| You may want to also check on the compatibility of the two units. A friend
| has a 430 and Navaid in his Velocity and found the Porcine Smart Coupler
for the
|
| Navaid wing leveler uses a data steam from hand held GPS units which is
| different from that from the panel mount 430. Apparently that can be
overcome but
|
| does require modification.

| The last time I saw a Navaid wiring diagram, it used analog

| following information on this topic on Nav-Aid's website:
|
| http://navaid-devices.com/coupler2.htm
|
| They're still an analog input autopilot. They've joined
| forces with Porcine Associates who developed a coupler
| that converts the digital output from hand held (and
| most panel mounted) gps receivers to mimic a VOR receiver.

| sure . . . this wasn't a single crack event . . . each of
| the four mounting ears was independently overstressed. Each
| parted the rest of the alternator individually. The
| initial examination of the fractures shows no casting flaws.
| The remaining ear was close to failure. It broke off with
| a pair of pliers and hand-generated bending stresses.
|
| We think the bolts were tightened down too tight and gasket
| thickness was reduced enough to bow the flange and put an
| abnormal bending load on the ears.
|
| If it were my airplane, I'd pitch the paper gasket and
| use a suitable brush-on gasket replacement material that
| would extrude out and avoid bending loads by getting the
| two machined flats to lay right against each other.
|
| This is only failure of the type for this product for
| several thousand installations. Although this event
| transpired on an experimental airplane, it's the same
| alternator as the STC/PMA installations . . . they're
| going to do a full investigation and report for the FAA.
|
| We'll post the final analysis results here on the AEList.

| From: Dj Merrill <deej@thayer.dartmouth.edu>

<deej@thayer.dartmouth.edu>
|
| Hi all,
| I'm rebuilding/rewiring some of the electrics on a
| used Glasair that I bought, and in particular know that the
| alternator field cut-off switch is not "right" at present.
|
| It is currently sourced from the instrument panel
| power switch (which is in turn sourced from the master
| power switch), and is simply a cheap switch that looks like
| it came from Radio Shack.
| I'm thinking of rewiring this to use a 5A circuit breaker
| in place of the cheap switch, and source it directly
| from the master power switch, and mount it above the
| low voltage warning light. My thoughts are that I can
| pull the circuit breaker, and that effectively acts as a "switch".
|
| Is this sound reasoning, or am I missing something critical
| and there is a better way to do this?
|
| Thanks,
|

|
| Much has been written about unstable voltage regulators in
| Cessnas and Pipers on "rec.aviation.owning". Go to Google
| Groups and do a keyword search for "pulsing ammeter".
| Here is one post that I wrote:

|
| Yes and no. The VR does "sense" the bus voltage thru this
| terminal, but since the field current to the alternator (about
| 3A peak) also flows along this wire, then if there is any
| resistance in this wire between the bus and the S terminal, then
| the voltage the VR senses is reduced by the drop across the
| upstream resistance. If the drop is more than a couple of tenths
| of volts, then this will cause the instablility (positve
| feedback). Even if it doesn't oscillate, then the drop will
| confuse the VR causing it to overcharge the battery.

|
| See above. 0.6 Ohms sounds high. My Piper has a 5A breaker in
| this path without instability. The Cessna just has a series
| switch with no breaker.

|
| If the battery is aft of the firewall, then the VR should be
| mounted near the battery so that it can sense the ambient
| temperature that the battery is subject to. The bus voltage
| should be 14.4 in cold weather and 14.25 in hot weather. If both
| battery and VR are mounted on the engine side of the firewall,
| then the bus voltage should be 14.2V once everything has warmed
| up.

|
| Last week, the tank-mounted electric fuel pump went out in my
| '98 K1500 Chev pick-up. Several $hundred later, I have a new
| pump assembly. I retrived the failed assembly from my mechanic.
|
| I was surprised that the assembly contains the fuel level sender
| in addition to the pump, a pressure switch and miscellaneous
| spigots. I took the sender off the pump, and checked it with an
| Ohmmeter. Shows 45 Ohms empty (float at bottom) and 250 Ohms
| full. The resistance element is a screened thin-film resistor
| on a ceramic substrate. The float arm contacts appear to be made
| out of phosphor-bronze.
|
| The unit seems to be well made. Much better than the senders
| used in Cessnas and Pipers.
|
| Homebuilders looking for a cheap source of a float/sender
| assembly could go to any auto maintenance garage and have the
| mechanic there save the "dead" pumps from GM vehicles. My
| mechanic says that he replaces a couple of these each week. Most

| I'd look for a relatively small pulley. Have
| your alternator's rotor balanced and spin it fast.
| One of the big advantages of an alternator is
| an ability to get useful output power at ramp and
| taxi engine speeds.
|
| A number of builders have been advised to increase
| pulley size to slow it down thus improving on bearing
| life . . . indeed this will probably make a poorly
| balanced rotor, or marginal bearings last longer
| but . . .
|
| B&C has been selling the ND alternators for
| about 20 years. They get balanced and they leave
| the factory with a small pulley. Wearout rates
| on these machines are phenomenally low while
| performance on the ground is as good as it gets.
|
| There are some OBAM aircraft that get into
| cowl clearance issues with larger pulleys . . .
| watch out for this too.

| Hi David,
|
| Various companies package a dielectric Grease. the tube I have in front of
| me is a 'Pematex' product that I bought at a local auto supply outlet.It
is
| labeled "Dielectric Tune-up Grease". The No. 22064 is at the bottom of
the
| tube
| It is commonly used on spark plug ceramics and wire boots to stop them
from
| bonding in place as well as water proofing them.
| This grease has a high content of silicone that will keep water and
| contaminants away very effectively. It will not easily melt and run off or
| evaporate.
|
| Although is referred to as grease, it is not intended as a mechanical
| assembly lubricant or bearing grease.
| I used it at all the ground wire junctions etc.

| The B&C ND alternators have always run well with a rather

|
|
| Alternators have two critical speed characteristics.
|
| Minimum speed for regulation: The RPM at which the
| alternator just puts out 14 volts but at zero current.
|
| Minimum speed for full output: The RPM at which the
| alternator will deliver rated output current at max
| operating temperature. Check out the drawing at
|
| http://aeroelectric.com/temp/80A_OutCurve.gif
|
| Here we see that minimum speed for regulation is
| about 1000 rpm for this exemplar 80A machine.
| Minimum speed for full output is about 6000
| rpm. This would be typical of most automotive
| machines.
|
| Bottom line is that if you have low voltage
| warning light and the light never comes on, your
| alternator is carrying system loads of the moment
| irrespective of its ratings or pulley size.

|
| sure . . . this wasn't a single crack event . . . each of
| the four mounting ears was independently overstressed. Each
| parted the rest of the alternator individually. The
| initial examination of the fractures shows no casting flaws.
| The remaining ear was close to failure. It broke off with
| a pair of pliers and hand-generated bending stresses.
|
| We think the bolts were tightened down too tight and gasket
| thickness was reduced enough to bow the flange and put an
| abnormal bending load on the ears.
|
| If it were my airplane, I'd pitch the paper gasket and
| use a suitable brush-on gasket replacement material that
| would extrude out and avoid bending loads by getting the
| two machined flats to lay right against each other.
|
| This is only failure of the type for this product for
| several thousand installations. Although this event
| transpired on an experimental airplane, it's the same
| alternator as the STC/PMA installations . . . they're
| going to do a full investigation and report for the FAA.
|
| We'll post the final analysis results here on the AEList.

| You're right. I was hoping to avoid teeing and getting in one of those
heavy

| Now does anyone around know of a SMALL and yet reliable pressure switch ?

| Nick,

| When you reply to an AEList post, trim away the original
| document as much as you can and still provide continuity
| to the conversation thread. In this case, you opened a new
| thread where none of what you echoed back to the list was
| relevant to the topic yet it was a huge document . . .
|
| If the aux alternator has only 8A rated output, I think
| it would be much better to configure the system using Z-13.
| If you want dual batteries, fine. Simply add second battery
| per Z-30. Which ever battery is tasked with e-bus support
| also gets the aux alternator connection.
|
| During main alternator out operations, you don't use
| any of the SD-8's limited output to keep a contactor
| closed. You have essentially all SD-8 output available
| for unlimited endurance bus ops. When airport is in
| sight, you can close both battery contactors and
| have energy to burn. See

I did just that a couple years ago, but I can't find the install manuals
on their site anymore. A call to their support might clarify things,
perhaps they can be downloaded on request.

Hi Bob,
What I meant to type was master power BUSS, not switch.
That's what I get when I let my fingers do the typing without
the brain attached... :-)
I guess the real question I have is would it be okay to
just use a 5A pullable circuit breaker instead of the
breaker and switch combination that is traditional for the alt. field?
My thoughts, which may be wrong, is that you'd want the
alternator enabled all the time anyways, unless there was a
problem with it, in which case you can pull the breaker just
as easily as throwing a switch. I'd source the 5A breaker
from the master power buss. The alt. field is currently
sourced through the circuit breaker that powers all of the
panel instruments (not avionics), which doesn't seem like a
good thing to me. I'd like to move it to its own breaker,
but due to very limited panel space, would like to
eliminate the switch and just use the breaker.
You've got me doubting my memory, so I'll have to go
check again to be sure, but I believe the master power
switch is only a single throw, single contact switch.
I think at some point I am going to have to rewire the
entire plane, since I have my doubts about some of the other
wiring as well, but am not ready for that task just yet.
Currently I'm just trying to improve a little where I can.

Have you checked with an alternator shop? They can

Unless you've tested your alternator/regulator combination
for sans-battery operations, you should consider shutting
of the alternator automatically any time battery is off.
This was the rational behind development of the infamous
split-rocker battery-master common to so many contemporary
production aircraft. It's also the reason all of our
suggested power distribution diagrams show a two-pole
DC PWR MASTER switch wired to produced the cited
behavior.

You can do as you've suggested but I don't recommend
it. If it were my airplane, it would get a two pole
master switch -AND- an independent field supply
breaker.

I've highlighted the drawing you sent me. You have
a rudimentary trouble shooting task. Someplace along
the pathway highlighted there is a short and/or failed
component. I'd start at the alternator and momentarily
disconnect wires until the breaker stops tripping. When
you find the first clearance point for the fault, the
problem lies between the last point where the fault
existed and the first fault-free point. See

--> AeroElectric-List message posted by: Mark Phillips <ripsteel@edge.net>
I am installing my 760 and have run into the conflict between the
Microair manual and Bob's Audio Iso Amp (which I am using)
instructions. Microair says to keep the microphone grounds separate
from supply negative (using pin 2 on the connector exclusively) and to
connect all other signals to supply neg. The Audio Iso Amp drawing 2.1
shows the headsets and PTT grounds sharing pin 2 with the mics. My
instinct is to connect as Bob advises, but why the note in the Microair
manual?
Also, the intercom switch is shown with a panel ground- is there a
specific reason this is segregated from the others?
I recall some discussion on the A-list some time back but after much
archive-wading could not find it- sorry to rehash!
Thanks!

Effectively, in its current wiring, and my
proposed, the alt field power is cut whenever the
master power switch is off, thus disabling
both battery power and alt power at the same time.
The circuit breaker will allow independant cut-off
of the alt. field, leaving battery power running.

I know. The wiring at present is a mess, IMHO.
I'm just trying to clean up the electrical mess on the
plane, and literally will have to rewire a lot to
make it "right" in my opinion (and yours).
Short term, I can at least make the alt. field cutoff
independant of the panel power, and long term, I need
to redesign the panel to have the room to put in
the appropriate breakers and switches.
I just wanted to make sure I wasn't making
anything worse by my proposed change.
I'll poke around to see if I can find a two pole
switch that will fit in place of the single pole
that is there now, and make it part of the short term fix.
Thanks for the advice and the great
book - it has been enlightening!

Hello Neil,
the list will not send any attachements to you and you should know, that
most
of the today's mass mailing worms are spoofing the sender adress, all
entries!
So you can hope that finally the originator finds out about his infection by
himself.
I can only urge to everybody, use an always current virus scanner and update
at least
once a week or even better get one which will update automotically.
Kind regards

Take a look at the S700-2-10 from B&C at
http://www.bandc.biz/cgi-bin/ez-catalog/cat_display.cgi?11X358218
This is a progressive transfer switch that will probably
fit the space you have. It mimics the operation of a
split rocker when wired as shown in the Z-drawings.

Wire per http://www.aeroelectric.com/Catalog/avionics/760imB.pdf
page 2.1 of drawings in the back. The reason I wrote my own
installation manual for the 760VHF was because of less than
clear and/or well reasoned instructions and terminology
in the factory manual.
>Also, the intercom switch is shown with a panel ground- is there a

It doesn't matter where this grounds . . . it is not a signal
line and is easier to ground it to the single point panel ground
than to tie it back into the radio harness.

The Navaid does not need a coupler to "Talk" to the Garmin 430. The Navaid
should be hooked up as follows: 1) Locate connector
P4001 on the Garmin 430
2) Pin 21 is the "Main + Left"
3) Pin 22 is the "Main + Right"
The above outputs will let the Navaid get a course deviation signal
from either the GPS Portion of the 430 or the VOR/LOC Portion depending on
which you have selected during a flight to use.
Couplers are rarely needed with panel mounted GPS'S but almost
always needed when the Naviad is used with a Portable GPS.
