Welcome to the wonderful world of yearly Microsoft upgrades!
My advice - buy Microsoft stock, so every time you have

The Visio 5 version of the file should work with all

I think I have a bad strobe. How do you test a strobe bub.
I checked the power supply, I have 230+ volts at the red wire and neg 0
on the white. I am assuming the black is ground.
Appreciate any help.

Bob,

That's a long, always hot feed wire. Not sanitary but then, it's
YOUR OBAM airplane.
For my continued education, can you elaborate on why it's not sanitary?
The 10AWG B lead would be about 12" long with a 20A ANL current limiter at
the contactor. If the B lead wire or SD-20 shorts, wouldn't the current
limiter open, saving the battery, just like the fusible link between the
contactor and SD-8 on Z-13 (while in backup mode)? Or might there be
leakage through the backup devices, draining the battery after shutdown?
>Would this give me the best of all worlds, ie with contactor closed, retain

Contactor failure is rare. Probability of contactor failure during
instances where high endurance bus loads are necessary are even
more rare. If that's a major concern for you, I'd consider Z-12, dual
battery contactors, with SD-20+FAT altenrator and eliminate the
e-bus entirely. With 20A of standby power, there's no probability
of wanting to operate battery-only and the value of a dual-feed
e-bus is diminished.
This has a nice ring to it! Looks like it eliminates my contactor failure
concerns, my always hot B lead issue above, provides dual feed to the bus,
retains autoswitching, eliminates the extra complexity of the E bus, gives
the pilot choices in what devices to unload during backup (until overload
light stops flashing, right?). There has to be a catch????---besides $ &
weight.
If I go with dual contactors, & eliminate the E-bus, what failure modes (if
any) might I encounter during flight which would require me to open both
contactors?
Would the contactors be wired in parallel, ie one simply backs up the other
by jumping the fat wire terminals and replacing the existing 1-3 AUX
alternator switch with another 2-3 master switch?
This may sound like overkill, but any merit to using 3 position master
switches like on Z-13 and reset only field breakers? Or stick with 2
position switches and pull breakers? (I guess I am asking if with dual
contactors, there may be a need to open either field without opening its
contactor?)
PS: To help me with my decision whether to go with the SD20, do you
estimate weeks of months before you have some test results & direction on
the SD-8 voltage regulator concerns?
Thank you! Scott RV7A

My library doesn't include the VOA-5. Is there an avionics
shop nearby? Many times, these shops have an extensive library
and will allow you to copy data for little or no cost. They
may also be able to support you with low quantity purchases
of harness parts.

Mystic River, the new movie being released this Wednesday is starring
Sean Penn and Tim Robbins who have been known to spew hate speech against
our current President, assaulting his character for doing what he is
attempting to do with the war on terror, to protect Americans from further
attack. Which has been very successful so far. These 2 liberal actors have
sided with Saddam Hussain and Osama Bin Laden and against our own country,
as demonstrated by Penn's going to Iraq prior to the war in protest of our
pending attack to remove the terrorist regime of Saddam Hussain, saying that
we have no right to attack innocent people and that it was the Bush
administration that is starting this war. Let us not forget 9/11/2001. I
figure I have no way to let the liberals in Hollywood know that they are

actors won't be able to get a job. Look what it did for Alec Baldwin's
career! He's a washed up actor that watches his mouth these days. We have 2

Z-14 is the system of choice for airplanes like a Lancair IVP
with dual everything and a pilot that's comfortable with
spending lots of time in weather that most of us avoid. This
is the style of electrical system that SHOULD be in airplanes
like Kingairs and Beechjets but isn't.
Z-14 can can be implemented under reasonable cost and weight
budgets compared to contemporary certified ships . . so it's
not necessarily contra-indicated for the builder who wants
the best . . .

Your sense of my thinking is correct. What we need to consider
is that the vast majority of builders bring a lot of baggage
with them from the experience (and hyperbole) from their membership
in the certified world. Remember that a large percentage of
dark-n-stormy night stories in the journals deal with electrical
system adventures -AND- they're always about system designs
and hardware with a PROVEN lousy track record with respect to
modern hardware.
Simply fitting the certified ship with a ND alternator
and well-maintained RG battery would probably negate most
of the dark-n-stormy night stories without having to
alter architecture at all. Add the E-bus and we'd
wipe out all but a few of the nail-biters that read so
well in front of a warm fire on a winter evening.
Adding a substantial second engine driven power source
to craft the two-layer electrical system depicted in
Z-13 offers outstanding system reliability numbers
because of inherent tolerance to most common failures.

Do your load analysis and convince YOURSELF that 8A
of continuous second-source power will keep the E-bus
alive indefinitely so that battery reserves are held
for approach to landing phase. If this exercise yields
attractive numbers . . . then I believe you have
all the information you need to make the choice
with understanding and resulting comfort.
Now, this still leaves some lingering questions
as to the physics of heat rejection for the SD-8's
regulator. I have a new regulator on the desk in
front of me courtesy of B&C . . . I'll try to get
started on the study this week. In any case, if
the current SD-8 regulator is found wanting, there
WILL be a suitable alternative available soon that
will make sure Z-13 is not fitted with hidden
shortcomings.

Wwap the non-working tube with one that is. See if the problem
stays with the bulb assembly or with the location on the airplane.
If you have a 'scope . . . check to see if you have a healthy
trigger pulse appearing on the white wire . . . it will be very
short but should be on the order of several hundred volts.

Thank you Phil. My problem is the light bulb is recessed in the holder and
I did not build the airplane. If I had some spare bulbs I would risk
breaking the bulb by using pliers. I am also not familiar with what the
base of a bayonet bulb looks like. These are suppose to 10,000 hour
bulbs. It connected with 22 gage wire. I was thinking of hollowing out a
pencil eraser to see if I could push and turn. The question is
serious. If the bulb is burned out I would switch with the power on bulb
since I much prefer a low voltage warning. The Feb panel rebuild to IFR
capable get LED warning lights.

Although not obvious from the appearance of the (yellow) lens, the base
of the bulb is threaded like a miniature household light bulb, so it
actually screws into the holder.
If you get the bulb out, you can also check to see if the holder is
getting power and check continuity to the regulator. One side of the
holder goes to a main bus fuse. The other side of the holder goes to
the regulator. (Pin5?)
I, too, like LEDs for their reliability and used them for the rest of my
panel indicators (some of them are ultra-bright LEDs). I retained the
yellow low-voltage warning lamp that we're discussing for obervability
reasons. It really gets my attention! Because I have dual electronic
ignition and a single alternator, it is important that the low-voltage
warning can draw my attention from what ever task I'm performing. My
suggestion is to get the indicator working so you can see how you like
it before you replace it with an LED.
I don't have a photo of the bulb. The photos of the bulbs on the B & C
website are too small to be of use, but my guess is that B & C
www.bandcspecialty.com could set you up with a replacement bulb for a
very few dollars.
Good luck,
Phil

Thank you Phil. My problem is the light bulb is recessed in the holder
and
I did not build the airplane. If I had some spare bulbs I would risk
breaking the bulb by using pliers. I am also not familiar with what the
base of a bayonet bulb looks like. These are suppose to 10,000 hour
bulbs. It connected with 22 gage wire. I was thinking of hollowing out
a
pencil eraser to see if I could push and turn. The question is
serious. If the bulb is burned out I would switch with the power on
bulb
since I much prefer a low voltage warning. The Feb panel rebuild to IFR
capable get LED warning lights.

Try this:

You will need the male pin. If it happens again, you probably have a bad
female pin in that slot. You will need extract tool to get old bent one
out. And you will need the little $40 crimper that they sell for crimping
the new pin before inserting in the d-sub.

Matt,
I haven't been following this thread closely but if the bulb has enough
clearance from the housing a piece of vynil tubing with an i.d. about the
same as the bulb diameter can be used as a "soft" wrench for those places
where fingers won't go. You might need to experiment with the size to find
something that will grip the bulb firmly. It should work with either
bayonet or screw type bases if the bulb isn't seated too tightly.

<<My LR3C-14 seems to working fine since it delivers 14.2 to 14.4 volts with
the engine running and when I connect an external test light between 14
volt buss and terminal 5 I get a blinking light. I assume that little low
voltage warning light bulb is burned out. How do I get the bulb out of the
holder? Access form the back of the panel is impossible without removing
the panel from the plane and that is not scheduled till mid Feb. Matthew M.

Hello Matthew, You don't say which fuse or CB you are using to feed the LVL.
If that fuse or CB is out the light will not come on.
There is a related issue on choosing which fuse or CB to feed the LVL. I'll
copy below a previous posting on this subject that may be of interest to you.
If you wish to follow up just search for LR3B-14 Voltage Reg Function.

Hello Mark, Which breaker you pull would be a function of which breaker you
are using to power the LV light. The LR-3 just completes a circuit to ground to
activate the light.
If you've wired the LR-3 as per B&C instructions pulling the field breaker or
opening the alternator switch will not turn off the light.
There was a short thread a while back on which is the "right" breaker to use
to power the LV light. The B&C instructions say to use the bus voltage sense
breaker feeding pin 3 of the LR-3 to also feed the the LV light. I chose to do
otherwise for reasons given in the thread. I'll resurrect it for you if you
are interested.
My approach would be along biblical lines: "If thine LV light offend thee,
pluck it out" ie just loosen or remove the bulb. Just don't forget to screw it
back in before next flight.

| Subject: | Xpdr wiring harness question |
--> AeroElectric-List message posted by: "Rick Fogerson" <rickf@cableone.net>
Do not Archive
Hi Bob,
Received wiring harness fine. One question! The diagram shows the power wire
from pin 24 of the xpdr going to the Essential Bus with a 5A CB for protection.
Is this a special case requiring a CB or can I just use the normal 5A fuse?
Thanks,
Rick Fogerson

What if the OVM fails to do it's thing during the in-plane test? I'll
subject everything on the master buss to abnormally high voltage.
Right? Is this a concern? Should I pull all the fuses from the master
fuse block first?
Thanks,
