I had planned to put electric seat heaters in my Velocity, but I didn't get around
to it before finishing the interior.
But I ran across http://www.baproducts.com/rphb1101.htm for a 12 vdc electric blanket. I haven't tried them yet but this looks like a great idea compared to the seat heaters I found - they were running over $200 each.

--> AeroElectric-List message posted by: "Neville Kilford" <nkilford@etravel.org>
I often find that rental aeroplanes have four seats, but only two headset
sockets, which makes for a dull trip for the hapless rear-seat passengers.
Can anyone recommend a simple way of making a double adapter? Perhaps it's
as simple as putting a couple of sockets in parallel, but I'm nervous about
trying it in case I damage intercom, headsets or both.
Any advice would be well appreciated. Thanks in anticipation.

Paralleling headsets all together on a single feed is exactly
what the intercom does. Drive ahead with confidence.

Chris Heitman asked this question on the RV List a few weeks ago and got no
replies. Since I have the same problem, I will ask again.
I have a GRT 4000 engine monitor and Lightspeed Plasma II electronic
ignition. I am getting a zero reading on the GRT tach. Pulses is set to 2
as specifies by Lightspeed.
Has anyone gotten this combo to work?

I did research on seat heaters myself. If you have not done your seats yet, imbed
the heater stips in the upholstery like the car manufacturers do. Run the
proper wires to a switch and concealed connector for the GIB. This will eliminate
wires attached to cigarette plugs going to heated vests, or blankets.
I dunno about you, but wires all over the cockipt offends my sense of cockpit
style. When it's warm, or when your safety of flight gear is drawing a bunch
of current, don't turn it on. Weight is very low, the current draw is not.
I've also included a site with inflatable lumbar pads you can imbed in the seat
foam. See them at:

Thanks, Bob, that's just the sort of info I like!
I never realised how expensive the aviation sockets are. I'm surprised that
no-one has ever consider swapping for more common ones (2.5mm and 3.5mm jack
plugs for example).

Jim,
The Radio Shack PN that I think is equivalent to the Boostaroo is 33-1109. Radio
Shack web page lists it for $21.99.
My GMA340 installation had sufficient volume with my CD player to hear the tunes
when the engine was not running, but not sufficient volume when the engine was
running. The Radio Shack volume booster gives sufficient volume with the setup.

I seem to recall a schematic for cleanly (noise wise) wiring the Nova supplies
using the foil shielded triple wire they supply but can't seem to find it, can
someone refresh my memory?
Trying to find the cleanest way to do something with the drain wire and also suggested
wire sizes going out to the nav/pos lights (do I really need an independent
ground to the single point firewall ground or will a twisted pair work?).
Thanks folks.

I have a large capacity Precision alternator (installed) that I would like
to limit for a basic VFR-only RV-9A.
I have installed the Vans 40 amp shunt. I notice that the smallest current
limiter in the B&C catalogue is also 40 amps (C905-40). I was looking for
about 35 amps so as to not having any nuisance problems.
Is this a problem? I don't want to risk blowing the Vans 40 amp shunt. The
extra amps would be a nice cushion for the seat heaters and that initial
load on the pitot tube heater.
This seems safe - but I want to be certain. Thanks for any help.

--> AeroElectric-List message posted by: "Matt Prather" <mprather@spro.net>
I might not understand your question exactly, but I think you
are asking whether the shunt can be damaged by running too much
current through it. If yes, please read the following... If
not, please ignore.
The shunt is a resistor of a precisely known value. It is designed
to give a calibrated voltage drop at a rated current. This voltage
is then fed into a specially calibrated voltmeter with a scale that
reads in units of current (appropriate for the shunt). The shunt
that I think you are talking about is rated to have a 50mV drop
when 40A are passing through it. If you pump more amps through
it, the voltage drop across it will increase.
So, the short answer is that I don't think you will damage the shunt
by 'over driving' it, per se. The only bad effect you might encounter
is if you are using a mechanical meter. The meter may read full
scale when it receives a 50mV signal. Any more than that, and it may
tend to damage the mechanism. A little over drive, ocassionally,
shouldn't really hurt it though.
The other thing to ponder is how much power you are asking the shunt
to dissipate... P = I * V. In this case, that's 40A * 50mV = 2W.
That's kind of a lot, but by the same token, these shunts are designed
to be fairly stable with temperature. This suggests that it is a
resistor rated for a lot of power, so 2W is probably not a big deal.
If you momentarily loade it to 3W (that's 60A), its probably still
okay, and 4W (that's 80A) might be okay with the shunt too, though
Amperage readings might get a little wacky because of heating.
So, I don't think you need a current limiter to protect the shunt,
though you may want one for other design considerations.
Hope that helps.

Sure, I'll e-mail it to you when I get home. It is in fact in Excel. It's a
work in progress, but it tracks the airplane parts by part number, serial number,
and date installed. Just part of my effort to start figuring out this airplane
I bought.
If anybody else wants a copy, e-mail me.

Hello Pete, I like this idea. Could you send me your spreadsheet as an
attachment to an email if it is in Excel? I'd like to use the format to construct
a
similar document for my airplane.
Many thanks.

Where are the RV6 / 7 builders putting the primary and secondary fuse
blocks in the aircraft? I'm having a difficult time finding room for
the two regulators and fuse blocks and need some creative help.

Twisted pair isn't designed to reduce radiated noise. The conductors don't actually
block one another from transmitting, at least not much. You need coaxial,
or some other type of surround-shielding for that. (How that works is a Physics
question, pick up any Electricity and Magnetism text for a lecture on one of
the more boring aspects of electricity, unless you love math.)
What twisted pair is really designed to do is RECEIVE noise equally in both wires.
It sounds odd to want to double the received noise, but in a rather elegant
engineering trick, the receiver simply subtracts the two signals from one other,
cancelling the noise, and leaving it with the original signal. Without getting
into the details, more twists per inch is more expensive (more copper in
1000 ft. of cable) but better at supporting noise rejection (more likely to induce
the noise perfectly equally). This is one of the deciding factors in the
higher "CAT" ratings you see - CAT5e vs. CAT5, for instance.
So, if you really care about radiating noise, use shielded wire, but don't waste
your money on twisted pair. I'm running a CAN bus so I may have a use for it,
but I can't imagine many other general aviation uses that would REQUIRE it.
Back to your original questions:
1. B&C sells foil shielded three-wire cable. Unfortunately, nothing larger than
22AWG, so check the power requirements for your lights.
2. Connect the drain wire to ground on ONE END of the cable (preferably at a single-point
ground near the battery).
3. Wire sizes require knowledge of current requirements - how much current will
be passing through these lights? (Do you have a wattage rating? Does the Nova
supply have details on this?)
4. You don't NEED an independent ground, but if you form a ground loop those wires
will become antennae and you'll be radiating noise more surely than not using
shielded wire. You CAN share a single return wire, though, although opinions
vary for the wisdom of this method.
Regards,
Chad

--> AeroElectric-List message posted by: Joa Harrison <flyasuperseven@yahoo.com>
Thanks for your reply. Just now I used a battery and figured out where all the
wires on the strobe/nav/pos head go....
Red w/pin---------strobe
White w/pin------- grounds to case
Black w/pin-------- grounds to case
Red--------nav +
Red-------- position +
Black------- position ground (not to case)
Case-------- has a braided line captured between the case and the aluminum mount
I'm using the triple wire I got from Nova. It has the pinned red/white/black wire
plus a bare stranded wire (the "drain" I believe).
I will also have 18 ga positive and ground wires going to my supply (through a
fuse and switch).
1. What should I do with the drain wires?
2. What should I do about the grounds that ground to the case of the strobe head
(and hence my airframe unless I completely insulate the case from the airframe
which mechanically would be a pain)?
What I don't get is why they have the strobe and nav grounding to the case but
not the position light (it has it's own independent black wire ground). Any ideas?
Bob, would a simple diagram make a good addition to your book? I know it would
sure help me out and I believe others using the Aeroflashes and the Whelans (they
are similar I believe).
Thanks folks. Sorry for being so dense on this one but I've spent enough time
and money trying to keep noise out to this stage that I want to get this one right
too.

Some of you probably already know this but Google has a feature for doing unit

Can somebody please help me.
During this very cold time in Switzerland I get troubles with my 17Ah
Panasonic, if the engine starts not at the first time, or if the plane sits
for several weeks. So I'm going to fit the Piper/Cole Hersee connector.
I've searched yesterday through the Bob's site as well as the B and C site
but could not find the crowbar OV module as a part.
Is this module not available as a part, or did I just miss it?
Many thanks for pinpointing
Werner

Hi all,
I have heard about "ground loop". Who can tell me more or indicate where are the
things I have to read ?
I am thinking about the wiring of my MCR SPORTSTER.
I will have a ground block under the seats and a mini battery bus (fuse holder)
for the trim and flaps (and can be later for the heating seats!!). I would have
also a ground block on the firewall (engine side) and finally the principal
bus, the essential bus and the main ground block behind of instrument panel.
For information, MCR SPORTSTER is a composite carbon epoxy aircraft and the tank
is located between the firewall and the instrument panel.
Do I risk problems with this ground blocks layout ?
Thank you for your answers.
