Bob,
Finally got around to trying the gauge without the internal battery. It
doesn't work at all without it so it appears that I'll have to figure
out some sort of power conditioning setup.

An actual gubment inflation calculator is at:
http://minneapolisfed.org/Research/data/us/calc/index.cfm
I worked at a gas station in 1962 and remember cost of regular of
about .32/gal and varied little, unlike today. That's then $1.95 in 2003.

Here's the site. It doesn't calculate based on a fixed average
rate but on empirical data. For example, $1.00 item in 1960
costs $100.00 in 1960 costs only 101.60 in 1961. $100.00
in 1975 jumps to $109.10% for 1976!!!! That was one of the
years we were taxing ourselves to prosperity. I bought my mom
a house about that time. Best mortgage I could get was 14%.

If there is any difference, it's insignificant and
not worth worrying about. I'd have no problem cranking
the engine with the alternator already on. "Spikes"
for the most part do not exist in any way that warrants
concern.
The split rocker is expensive, not particularly
long lived and doesn't match any other switch in
the panel. If you haven't already mounted it, I'd
suggest that it never get mounted. See articles
on aeroelectric.com for more on switches, switch
ratings, and other documents I think you'll find
useful.
I will invite you to join us on the AeroElectric List

Well considered and technically elegant answers to
all of your questions are waiting for you there. Also,
check out the downloadable materials at
http://www.aeroelectric.com
It would be much better that you craft decisions based
on an understanding of goals, materials and architectures
than to go with a consensus of opinions no matter who
offers them.
Thanks!

--> AeroElectric-List message posted by: "Robert L. Nuckolls, III" <bob.nuckolls@cox.net>
Subject: Re: Unstable charging system . . .
A couple of things to update you on:
You had asked in the past about fuse or circuit breaker,
and I do have a 35AMP circuit breaker.
I was wondering about your field supply line. If you
have a 35A breaker (this would be the b-lead breaker
on the bus) there should also be a 3 to 5A breaker
for alternator field supply. Since this breaker is
in series with the alternator control switch, it too
can contribute to the loop resistance that gives
rise to your observed alternator instability.
. . . . . I have been cleaning
and buffing the copper bus connections, and the ring terminal
connection from the alternator B terminal. I was looking
at the switch again, cleaning up those terminals, and did
find a suspicious ring terminal from the alternator F.
It was replaced. I cleaned up the terminals at the starter
relay S and Ammeter lines, and did another test run.
Still no change.
The problem WILL NOT be in any wiring or components
associated with the b-lead connections that deliver
power to the bus . . .
I am ready to rewire the whole system, but my worry is it
will still do the same thing if I can't check the switches
and circuit breaker accurately.
Just put in new alternator field breaker and new
split rocker and if you like, renew all the wires between
alternator field breaker and the A/S terminals on
the regulator. The problem will go away for another
10-40 years.
In on of you past e-mail you wrote about an LP3, what is that?
I guess if I'm going to do all this redo I would like to consider
anything that might add longevity to this system instead of
this relatively short run on this try.
This is a regulator (LR-3) designed for the OBAM market and
has been successfully installed on hundreds of
certified ship via 337. However, the system you have
is quite capable of satisfactory performance. It's just
getting long in the tooth and needs a Saturday afternoon's
dose of attention.

Since the production plane I have has a split rocker, it never occurred to me
that it isn't really needed. To be honest, 99% of the time I switch them on
together. About the only time I don't is when I just want to turn on a
Radio.
The new Tiger has a radio that is wired to directly to the battery (though a
fuse) to allow for using the radio on the ground without going through the
master switch. Interestingly enough, it's paralleled to an avionics master
switch so it comes on with the avionics master as well.

I'm afraid that's not all your faulty message did. It also
provided me, evryone on net and Lord knows how many spammers with a neat
concise and full list of all the firms with which we deal. Thus, you have
probably added another vast series of spam messages to these good people.
If you must produce a long and interesting list of victims, do
so on B.c.c: - Blind Carbon Copy. That way the only person to see a

they are the culprits collecting and selling lists to the unscrupulous and

. . . It came up as part of a discussion about the trade-offs between
OBAM aircraft and certified ships wherein I noted that while
costs for many products we enjoy have grown at less than rate
of inflation, some things (most notably those controlled by those-
who-would-protect-us-from-ourselves) have grown at 3x the
rate of inflation. A C-172 SHOULD cost less than $50K today.
Folks asked how I arrived at that deduction and I forwarded
and interesting link for those who would care to check on other
products http://www.westegg.com/inflation/
This of course would include nifty things like a hand-held GPS
receivers which could easily be over $1,000 instead of $100 . . .
As for the archives, I (and I'm sure most others) are not really
concentrating so much on how history views what happens here
as we are on which direction we are going . . . but in the spirit
of good list citizenship, I'll suggest that this message should
be in the DO NOT ARCHIVE category . . .

| Subject: | LED Panel Lights |
--> AeroElectric-List message posted by: "Jon Finley" <jon@finleyweb.net>
Hi all,
I'm working on a panel lighting project and am looking for some input.
I fly a Q2 which, for a seatback, has a full height bulkhead and full
canopy. I would like to install two LED clusters in this seatback
bulkhead that shine on the panel. I don't have individually lighted
gauges and don't plan to install post lights. So, with that in mind:
I have searched for LED clusters I have found these units
(http://www.jameco.com/cgi-bin/ncommerce3/ProductDisplay?prmenbr=91&prrf
nbr=4151&cgrfnbr=501&ctgys=) from Jameco (Jameco #150922). They don't
provide any beam width information, of course.
I don't mind fabricating my own mount and/or my own LED cluster.
Wondering if anyone has already done this and has tips that could save
the next person (me!) some time??
Thanks,
Jon Finley

List,
As I'm getting close to cutting out my panel (again) I'm getting nervous and need
confirmation of some things I am only95% sure ofon Figure Z-11: Could you please
confirm?
1) Grounding: Even though Iam buildingan aircraft with a steel tube fuselage I
am planning on running a separate ground cable from instrument panel ground bus
directly to the battery. Am I interpreting the drawing properly? The cable isn't
shown on the drawings I can find implications of not needing it in The Connection
chapters but I can also find implications that is the most important
cable in the aircraft (obviously it would be for a composite)
2) The alternatorFIELDbreakergoeson the panel and the alternatorOUTPUT cirquit
protection (probably fusible link in my case)goes near the starter contactor,
correct?
3) When would one want to pull the alternator field breaker to run on battery only?
Thanks,
Grant Krueger

Forgot one question I know it seems really dumb but I'd feel better hearing the
answer I'm 99% sure of.
I'm unclear about the starter switch on the panel: The way Z-11 is drawn the starter
is energized by a spring loaded toggle mag switch.That's whatI'm planning
on. I've been confused though bytalk ofpush button starters. I know they are
an option for those who like them but are they a requirement ( the spring loaded
toggle switch only allows current to flow to the push button starter)?
Thanks again,
Grant

All of the suggested versions will function. I prefer
to connect the alternator to the battery through the
shortest possible length of fat wire and if possible
by adding the least amount of wire. If your battery is
on the firewall, then the b-lead fuse can be tied
to either the starter contactor or bus side of battery
master.
If your battery is behind seat, then the starter
contactor is the best choice.
There is NO reason whatsoever that the alternator
should be wired to the main bus a-la spam-cans of
the past 55+ years. This was a ringer from the
beginning.
I will invite you to join us on the AeroElectric List
to continue this and similar discussions. It's useful to
share the information with as many folks as possible.
A further benefit can be realized with membership on
the list. There are lots of technically capable folks
on the list who can offer suggestions too. You can
join at . . .
http://www.matronics.com/subscribe/
Well considered and technically elegant answers to
all of your questions are waiting for you there. Also,
check out the downloadable materials at
http://www.aeroelectric.com
It would be much better that you craft decisions based
on an understanding of goals, materials and architectures
than to go with a consensus of opinions no matter who
offers them.
Thanks!

both. for mono you leave of one of the amplifier

You have do download their ECB drawing program and
install it on your PC. Then, you open the .pcb file
and use their program to order boards.
You can order a board from the AeroElectric Connection
for $20. Unless you're prepared to order 3 to 6 boards
at once and share costs with others, the most economical
approach would be ordering from us.

Hmmmm . . . yeah, lots of folks make these . . . but you
wouldn't want to place an order for just that one part.
Between minimum $ for ordering plus shipping, that little
part becomes pretty expensive. How long before Digikey
can ship, do they say?

They have 103 of the 18-pin version in stock if you care to Dremel or hacksaw one
pair of pins off (A133-ND).
Or you can just get a regular 16-pin DIP socket (such as A9416-ND) and insert the
resistor leads into that...

Chad

Sure . . . and it's easy. For an overhead flood, you probably
don't want someone else's idea of what a "cluster" of
LEDs is supposed to do. When you get one of the prefab
assy leds pointed the right way, you'll be lucky if more
than one of the remaining LEDs points where you want it.
I've built LED replacements for the overhead flood
in high wing ships like a Cessna using at most 4 and usually
only 3, hi-intensity red LEDs. Three lamps in series can
be powered from 12v with a 180 ohm resistor to limit current.
Just jury-rig a means for holding the lamps and positioning
them for best uniformity across the panel. Once you've decided
how many lamps and where they need to point, you can work
on hardening up the mounting for permanent installation.
Some builders have designed overhead floods to run from
an array of 9v alkaline batteries. For no more often than
you'll need panel lighting, three alkaline batteries will
give you approximately 30 hours of high intensity lighting
and 50-60 low intensity lighting. This would make your
panel lighting totally independent of ship's power.
If you want to work with white lights, use only 2
in series per 180 ohm resistor. Count on four lights
total, two separate strings.

correct

fuselink for 40 Amps, I doubt, the fuse goes as close a spossible to the
alternator, which might in this case be on the firewall close to the
starter contactor.

if you want to shutdown the alternator you pull the breaker, this could be
for test reason, or if you supsect the OV did not work or ..... and the
breaker is also triggered from the OV module.
Hope it helpes

Can someone tell me if M22759/16 aircraft wire is the same as Mil-W-22759/16
aircraft wire? I found the former on the web at a significanty less cost
than the latter.
Also I was reading http://www.expbus.com/pdfs/wiresize.PDF In this document
it states that AC43.13 gives a maximum allowable voltage drop of of 0.5
volts in a wire circuit. It gives an example of an 18 AWG wire and says the
maximum allowable length is 9.25 feet.
Yet in almost every aircraft wiring diagram I see nav lights wired with 18AWG
and the circuit has to be 30 to 40 feet. Can you explain this?
Im building a velocity and almost every circuit that goes to the rear is 15ft
one way. 30ft round trip. Certainly I dont have to use hugh wires for all
these circiuts Please Help?
