--> AeroElectric-List message posted by: czechsix@juno.com
Guys,
Is anyone interested in saving a few bucks on Bob Haan's WigWag Flasher
II? I purchased one a few weeks ago and changed my mind, deciding not to
use it. There's nothing wrong with it and it is new in box, uninstalled.
Bob takes returns but charges a 15% restocking fee. If you get it from
him it will cost you $156 including shipping. If anybody wants this one
before I return it to Bob, I'll let it go for $140 *including shipping*
anywhere in the U.S.
If you want to see the specs on it go to the website at:
http://users.easystreet.com/bhaan/wigwag.pdf
It's a nice solid state unit with all the features you could want...bulb
warmer, LED indicators, multiple modes, etc...and can be controlled via
low power switches from a stick grip if you like.

If you have an alpha wire catalog the part # is GRP-120-1/8. the last part
of the # is the size 1/8, 1/4,1/2, and so on. look on there web site
www.alphawire.com you may be able to find it there. look for expandable

As has been discussed on the list before, for completion of flight, the
position lights aren't all that important. Conversely, I think it would
somewhat more inconvenient to do a night flight without your panel
lights. If you lose your main source of power (alternator) I think you
will want to turn off everything not necessary for continued flight. That
would include your position lights.
Maybe you could have a single switch, and have the panel lights and
position lights being fed from two different busses. The bus that feeds
your position lights (main?) could also feed other non-essential (non-
endurance) consumers.

Bob,
Back to the overvoltage disconnect for my late model GM alternator (they call it
a generator as it puts out DC) and is internally regulated. To recap, you advised
that wiring the crowbar overvoltage device in the field circuit may or may
not actually take the alternator off- line, correct? Your recommended addition
of an extra circuit with a heavy duty contactor (105 amp) to disconnect the
alternator output will complicate the installation but is doable. Currently
I have the output going direct to the starter contactor via a fuse as per your
recommendation.
I suppose my question is what are the chances that (1) an overcharge condition
will occur to begin with; and (2) if it does happen what are the chances that
the elimination of the field voltage will not solve the problem.
I suppose an alternative is to modify the alternator for use of an external voltage
regulator.... how hard and/or expensive is this? Changing the alternator
is not an option.
Any comments or advice is welcome, thanks.
Mark Means

Some time ago I saw reference to a small "box" that you could attach to
the side of a Microair 760 comm radio, plug right in, and eliminate the
PTT for the intercom, among other features. (can't find my links!) I
thought it was on the X-air site at http://www.mcp.com.au/ but have dug
around there and other Microair related sites with no joy. I also
contacted MCP.COM by e-mail for info.
Anybody used one of these things or know some other way to get rid of
the PTT for intercom on the Microair radios?

I remember seeing that. I do believe it was something that X-Air was selling when
they were selling
MicroAir radios. Their new radios don't require them, so they may no longer be
available. I chose
to use a Flightcom 403 to eliminate the problem. It's small, light and reasonably
priced. And
works well.

I also have this combination, with a whole bunch of radio noise to boot.
Any time I throw a switch I get input in the headphones (engine off.)
I've spent these cold winter weeks reading and re-reading Bob's book on
the subject. Unfortunately it's too cold to stand in the hangar and
experiment. One question comes to mind though. Flightcom manual
calls for headphone grounds to return to the unit, which is itself
grounded. I ran the headphone grounds directly to the firewall-mounted
B & C groundblock. Any chance that's the culprit? Headphone and
microphone jacks are mounted in a piece of angle aluminum which is
mounted to my steel fuselage cage with rubber-cushioned Adel clamps.
Jacks themselves are mounted with the plastic and insulated washers
prescribed by Flightcom. No shielded wire was used except between the
radio and intercom.
I've been scratching my head about this for quite a while. Warm
weather can't come soon enough. Thanks very much.

Builders have used the 2-10 switch to control strobes and
position lights. Down is OFF, mid position is STROBE, up
is strobe + position lights.
>While we are on the subject, I am assuming that the AEC dimmer does not
>have an off function.
Correct. The dimmer is designed to have the max counter-clockwise
position of the dimmer pot to bias the lamps up at a voltage just
below usable output (about 4v). This means that as you rotate
the control, you get immediate perceived response from the action.
Dimmers that go to zero volts "waste" the first few degrees of
control rotation doing nothing but bringing the lamps up from
zero to first visible light.
There is no practical reason to include additional switching
to turn the lamps OFF . . . lamp life in the keep-warm mode
is about 10x the life of your airplane. See chapter on lighting.

When you say headphone, are you referring to both jacks (to include the
mic)? Or, this another way of asking whether you grounded the mic back to
the radio, or to the firewall? If you grounded the mic to the firewall, I
could
see this being the problem. I would be a little surprised if the noise is
coming
directly from a faulty ground for the headphone (the big plug) but not the
mic.
From my limited experience, it seems like you are likely to pick up noise on
the input to a buffered or amplified circuit. The mic side qualifies, but
the
headphone side does not. That's why I can see using sheilded wire on the
mics, but not on the headphone. On the headphone side, the electronics are
already done amplifying the signal, and noise will probably be of the low
voltage/
current variety.
All bets are off if the headphone amplifier doesn't use a common ground,
ie, the
negative headphone output needs to be grounded, instead of floating, by
design.
If that were the case, returning the negative lead of the headphone back to
the radio would be critical. I doubt this is an issue.
Interesting question. Please let us know what you find.

Matt Prather

Do the lamps drain battery when they are "Turned Down"? If so, I assume you
would not want them on the battery bus without some additional switch?

Depends on the alternator and experience of who's doing it.
B&C routinely modifies hundreds of brand new ND alternators
to turn them into aircraft alternators . . . but their
tooling and experience level makes this a fairly easy
task . . . however, I wouldn't try it myself.
I have modified some older machines with reasonable
success but nature of the task can vary widely from
model to model even within the same brand.
I'm not familiar with your particular part, you can
ask an alternator shop about the task and see if they
would like to take it on. Many of my builders have
gone this route over the years. I cannot recall hearing any
negative feedback on the experience so this is certainly
an option to consider.

See chapter on antennas in the AeroElectric Connection. The

Soft aluminum tape is VERY difficult to make an
electrical connection to that is also mechanically
robust . . . use copper strip. Hobby shops like
Hobby Lobby offer rolled, sheet copper that can
be cut into strips about 1" wide and then bonded
to the inside of your fuselage with something
like ShoGoo or perhaps an overlayment of glass and
epoxy.

Dear all,
another question where I'm a bit uncertain, even after reading Bob's Shop
Notes and comparing them with the Seminar wirebook. Maybe Bob, if you read
this could you comment?
Bob, in the shop note you say, that you use 3 wire shielded, and the shield
itself is connected on both (?) sides to the Mic LO, did you use the 3 wire
because of wiring both mic's to only 4 ports? (You used the shielding
instead of one wire).
I have a used Garmin 340, where I have a separate port for each mic/phone,
should I use a 2wire shielded for each mic using the shield as the third
wire (if yes, which contact should be wired with the shield)? Same for the
phones, if I use the same approach I could use a 1wire shielded wire for the
two contacts. It would save weight and money.
Many thanks for your feedback
Werner

Bob,
Do you know what the flash rate is of the wig wag unit that B&C is
stocking?
Thanks,

G'Day Bob,
I have a question regarding grounding - How do you suggest running the grounds
for a dual battery (both 12V/17AH) / dual alternator (40A main/20A aux) (similar
to Z14) setup in a single engine composite canard pusher? I have B&C fast on
ground buses on the panel and the firewall, and both batteries in the nose(FYIO
- I would have used one battery / two alternators but need the weight up front,
and figured a battery is better than ballast). I was thinking:
1. 2AWG from Main Battery -ve to firewall fast on ground bus (5/16" brass bolt).
2. 2AWG from firewall ground bus (bolt) to engine crankcase.
3. 4AWG from Main battery -ve to instrument panel fast on ground bus (5/16" brass
bolt).
4. 4AWG from Aux battery to firewall.
Do I need anything further? I'd like to avoid the installation complexities of
copper conduit - What would you do if designing grounds for this system?
I very much appreciate your time, and forbearance.
Cheers

I should have measured them while they were here. Sorry
'bout that. I would estimate each light flashes 2 times
per second alternating.

Sure . . . which configuration are you considering for system
architecture? Why would you run the lighting from a
battery bus?

Dual Battery / Dual Alt configuration. Was thinking that cabin lights would
be nice for night cabin/flight prep without requiring the batteries to be
turned on.
