For a check, if your intercom/audiopanel is switched off and you still can
communicate via the radio you would not need this extra wiring.

Bob: Thanks for the reply. Interesting that you mentioned an
overvoltage condition being the cause of the instrument that you
mentioned. You may rememeber a few weeks ago I had a overvoltage
condition on an internally regulated alternator. I started and within
15-20 seconds shut down my engine after noticing the voltmeter peg at
maximum. I then removed the alternator, had it checked and found that
the regulator was bad along with some other problem. My problem with
the fuel gauge showed up on the first start-up after the overvoltage
incident after I installed the new alternator. All other guages, radios
seem to be fine. Maybe the OV condition caused the fuel gauge to simmer
and I didn't notice it before because I shut down the engine?? What do
you think? thanks again, Jack

Excellent data point. Yes, your ov event would offer a
strong suggestion of root cause. Given that your fuel
gage was operational for a period of time before the ov
event and croaked afterwards is a very powerful cause/effect
linkage.
Odds are that simple replacement of the smoked gage will
be all that's necessary. I'd like to get the smoked one
if you don't need it for anything else.
For the rest of the folks out there . . . here's another
isolated, rare, but not zero-risk incident involving
a runaway in an internally regulated alternator. I've
fielded a lot of tomatoes and cabbages over this issue
but I'll have to continue to recommend (1) the BEST
alternator installation for aircraft use external
regulators with ov protection either built in or as an
ancillary device or (2) some means of adding external
ov protection to the internally regulated alternator
is a GOOD thing to consider.
Jack, do I recall correctly that you only had 30 hours
on this airplane when the alternator launched for the moon?
Also, for the next few hours, be especially watchful
for damage to other systems that may not have surfaced yet.

I recently purchased a new Lightspeed XCc headset for the passenger side of my
plane, to go along with the Pilot 17-79 I use myself. I tried it out on a solo
test flight and it worked very nicely for the price.
However, when flying with both headsets in use, I discovered that at high power
settings, the VOX setting on the intercom that works for either headset alone
produces nearly constant open mic with both mic's plugged in. If I turn up the
squelch on the intercom VOX, I can remove the noise and get it so that the
pilot-side mic works in intercom mode, but the pax-side won't break squelch.
If I adjust it so that I can hear the passenger in intercom mode, the wind/engine
noise reappears annoyingly and intermittently. At lower speeds and lower
power settings, this problem disappears.
The Lightspeed headset has a mic gain adjustment screw. Is it possible to reduce
the problem by changing the mic gain on one headset? Is this a "fly it and
try it" methodology?
Are there other ways to handle this problem (besides unplugging the passenger mic)?

Olympic Wire is the company that makes this stuff.

I bought 12 conductor coiled wire from them through a distributor, ALLIED

If all you need is a PTT the cheapeast solution might be to sacrifice a
cheap portable PTT.

Pascal,
Combining those two switches into one switch only makes sense if panel space is
critically tight. The master/alternator switch is a double pole, double throw
switch as Bob designed the circuit. To incorporate the Endurance (formerly called
Essential) bus into this switch would require a triple pole, double throw
switch. These are available, but are more expensive. Another down side is that
if your new, combined switch fails away from home, you will be hard pressed
to find a replacement quickly. I suggest that if panel space permits, you stick
with the setup as designed by Bob.

George: The alternator that failed was a nippon denso, 60 amp,

others to avoid this unit. I know that hundreds of airplanes are flying

you might decide to avoid all internal regulated alternators.

Just for newcomers to this discussion . . . I would not
discourage anyone from taking advantage of the very high
reliability offered by modern, internally regulated
alternators . . . your risk of suffering the alternator's
ultimate insult is indeed very low. Van's assertions that
thousands are flying trouble free for a remarkable history
of satisfactory service life are accurate. The odds are
definitely in your favor . . . especially if your particular
alternator selection allows you to directly control it while
being turned by the engine.
I'll add that my personal mission is to offer builders
the best I know how to do without suffering a huge
budget crunch. Yes, B&C wants an arm and a leg for
their products but in comparison to the total cost of your
project, it's not a big jump proportionately.
So I'll continue to offer my best recommendations but please
don't assume that because I cannot recommend a particular
philosophy or technique that I'm suggesting it's an evil
or extraordinarily risky thing to do.

I discovered another off-the-shelf source of small diameter
coil cord: Cell phone chargers for your car. I just pitched
a couple of charger cords I don't use any more. They would
have had a two-conductor cord suitable for PTT. If you need
more functions, the cell phone charger I have now is a universal
device with personality modules that plug in at the phone
interface. The coil cord seems to have 4 or more conductors
in it. When I trash my current phones, I'll let you know!
In any case, there are dozens of sources for new and/or
junk coil cords that can be pressed into service on your
airplane.

The problem you cite is very common when different brands
of mic/headset are combined into a single system. The
best intercoms have independent mic circuits that will
allow individual adjustment for vox thresholds and
mic sensitivity.
The system you have apparently does not have that feature
and there's no easy solution that I can deduce. Keeping
headsets paired for brand and model number is the only
way to improve probability of success.

I bought the PS Engineering PM3000 Intercom.
Wiring is pretty straight-forward, but I need to eyeball one aspect
of the installation.
It could turn out to be a real rats nest if not done properly.
The wire shields all come into the 25 pin Sub-D, connect to each
other, and together with some core wires, then a single ground wire
goes into the Sub-D through pin #1.
How on earth do all those shields mate together?
Can someone point me to a picture of the actual installation?
Many thanks

quite a bit cheaper.
When I was considering the single alt/two battery setup I was going to
get an Odyssey for my main batt (therby using its low internal resistnce
for max cranking) and a SLA for the secomdary.
I been using these for the last 6 years on my current airplane.

I've read the new chapter 18 on audio panels, and it hits most of my
issues right on the head. The only thing it lacks is a picture of the
end result in terms of what is installed on the panel.
Here is what I am trying to tie together:
Comm1: (Garmin 250XL GPS/Comm)
Comm 2: (VAL 760)
Intercom: Sigtronics SPA 600 with optional stereo music module
Warning: Redish stall warner (have to create tone generator per chapter 18)
Music: Sirius satellite radio
BX-2000 Audio selector panel
My basic question is - is it worth it (or even possible) to use the
BX-2000, or would I be better off to simply create something on my own
per chapter 18? The BX-2000 has lots of selections which I would have
no intention of using - so it fails the complexity proposed in ch
18... On the other hand, the audio isolator presented in ch 18 is mono
only it appears.
As an aside, I wish there were a panel "after" drawing in Chapter 18
to compare against the notional audio selector which is presented
early in the chapter.
Help help!

| Subject: | D-SUB Wye Band-Aid? |
--> AeroElectric-List message posted by: "r falstad" <bobair8@msn.com>
I just finished what I think is a very nice harness between my Ameri-King AK-350
altitude encoder and my Garmin GTX-320 transponder. Then I looked at the installation
instructions for my Garmin GNC-250XL Comm/GPS only to discover that
the Comm/GPS wants altitude codes from the encoder, as well.
The altitude encoder cable end is a 15 pin male D-Sub with female pins, the transponder
cable end is a 25-pin male D-Sub with female pins, and the Comm/GPS is
looking for a cable end with a 26-pin HD-DSUB.
I've been trying to crimp everything using the machined pins from B&C but can't
fit two 22 AWG wires into one pin (no surprise there). I could probably solder
two 22 AWG wires into the solder cups of a D-Sub connector. So here's my current
thinking:
Make a "wye" with one leg terminating in a 15-pin female D-Sub with male pins to
mate with the transponder cable. The second leg of the wye would be a 26-pin
HD-DSUB to match the back of the Comm/GPS. The connector between the two legs
would be a 15-pin male D-Sub with female pins to match the altitude encoder.
I'd have to go ahead and solder two wires into nine of the solder cups on this
connector (i.e., A1, A2, A4, B1, B2, B4, C1, C2 and C4).
Will the pins for the HD-DSUB accept 22 AWG wires? Does this lash up sound like
a plan?
Thanks and
Best regards,
Bob

The D-sub connector that came with my PS Engineering PM3000 Intercom
has pins that are not stamped, but seem to be tiny brass tubes with
colors on the outside.
I'll bet there's a crimping tool for these types of pins, but I'm
darned if I can find it.
The PS Eng manual says use "AMP 661966-1" tool, but neither Digikey
or Mouser carries such a beast.
Can anyone help, pls?

Hi Neil,
Go go to B&C Speciality's site :
http://www.bandcspecialty.com/cgi-bin/ez-catalog/cat_display.cgi?9X358218#RCT-1
Scroll down the page to: D-Sub Machined Pins Crimp Tool
I think this tool is what you need. The professional version of this tool is
way more money than You will likely want to spend.
Isn't wiring fun |;-}

Bob, I note that in Z-32, the wire from the S704-1 E-Bus Alternate Feed
Relay to the Endurance Bus does not include a Fusible Link, unlike the
Z13/8 drawing between the E-Bus and the Alt. Feed Switch. Should it be
there?
Thanks,
John

| Subject: | Built-in starter contactor/Z-22 |
--> AeroElectric-List message posted by: "John Swartout" <jgswartout@earthlink.net>
Bob, I'm figuring to use Z13/8 with Z-22 for my Sky-Tec Flyweight
permanent magnet starter with onboard solenoid.
In Note 10 you recommend locating the field breaker for the main
alternator (L40 with LR-3 in my case) not on the panel but as close as
possible to the starter contactor. My starter RELAY will be on the
forward side of the firewall. This would make it impossible to pull the
breaker from the pilot's seat in case of alternator troubles. But if
the main alternator died, I would still like to be able to start the
engine if I am stuck 400 miles out in the bush, so I plan to use the
progressive transfer, 2-10 style master switch discussed in Note 22. It
is not clear to me whether it would still be possible to start the
engine if the L40 main alternator is disabled. Does it matter that
there is no jumper from the starter solenoid hot terminal to the B-lead
of the SD-8?
And should the wire size from the pushbutton starter to the S704-1 relay
be the same size as it would be for a starter contactor, i.e. 20AWG?
Thank you once again for your generous assistance.
John

See http://aeroelectric.com/articles/strtctr.pdf
The extraordinary inrush currents common to modern starter
designs that caused extraordinary wear on the start switch
contacts of the ACS510 off-l-r-both-start keyswitch and
prompted an AD to add a diode across the contactor coil.
I prefer NOT to subject the ACS510 or any other panel mounted
switch to this stress and have recommended an auxiliary
starter contactor as illustrated in all of the Z-figures
-OR- use of a boost relay as depicted in figure Z-22 of
http://aeroelectric.com/articles/strtctr.pdf which not
only cures (1) a run-on problem with SOME PM starters when
using the on-board contactor (2) but isolates the panel
mounted starter control from the high current requirements
of the starter contactor.
By the way, if you ARE using a PM starter then figure
Z-22 may be the recommended control philosophy. Some of
these starters exhibit a delayed pinion engagement quirk
when back-emf during spin-down of the deenergized motor
keeps the pinion extended. These starters should be either
wired with ROBUST starter push buttons and heavier
than usual control wires (recommend 16AWG and 10A fuse)
-OR- per figure Z-22.

Where do you live? In any medium size town (300K or more)
there are usually corner Batteries-R-Us stores. There
are a half dozen in Wichita. You're looking for a form-fit-
function replacement for a 17 a.h. RG battery like:
http://www.aeroelectric.com/Mfgr_Data/Batteries/Panasonic/lc-rd1217p.pdf
Walk into the battery store and see what they've got before
you spend money on shipping for so large a hunk of lead.

If they're SLA, SVLA, RG, or SE batteries, then they're
the same chemistry and basic techology as the Odyssey.
Odyssey is a thin plate device offering exceptional
cranking current . . . but it's not a magic battery
by any stretch of the imagination.

that puppy is EXPENSIVE. B&C has one at a fraction of the
price at http://www.bandc.biz
It's their catalog number RCT-3 and looks like this . . .

and installs pins like . . .

Neil,
These are mil-spec pins. The crimper is about $350.00 from McDanials tool.
The one that B&C sells works fine for far less cash. Bob N told the class
that I attended that there were some problems with the early B&C tools but
that they had been corrected. I would suggest that you do not buy a used
tool as it might one of the defective ones. Don
