Interesting. The site is a bit weak on details though. I presume that
the experimental unit is internally regulated. I don't see how they
provide a means of removing field excitation to disable the alternator
in the case of a problem but that is probably just a matter of
insufficient information on the web site.
As for the versions for certified aircraft, there isn't a lot
information there either. I guess they are just bolt-on replacement for
existing alternators. Their point about superior output is a non-issue
for me. I have never seen a load on any of my alternators that exceeded
about 50% of rated capacity. Heck, on my Aztec I only hit 50% if one
alternator is off line. The rest of the time I can barely see the 60A
loadmeters (one per alternator) move.

Listers ...
I'm about to order a grounding kit ... what have most ordered for an IFR
platform with the usual glass panel goodies, engine management system plus
GPS/COM There are several ground systems listed at B & C and I only want to
order once.
This is their list:
24-Tab Ground Block
24/24-Tab Firewall Ground Kit
24/48-Tab Firewall Ground Kit
48-Tab Ground Block
Are there additional ground tabs required to accomodate avionics and inst
panel ground tabs or do the above listed include those?
Should the avionics and panel grounds be collected on local tabs and then
those wired directly to the firewall forest of tabs as well?
Many thanks to the list ...

Jerry,
I can speak to how I addressed this. I'm a few weeks from flying, but I
generally feel good about the wiring/grounding at this point. I've had
absolutely no problems whatsoever.
I used the 24/48 block. 48 are on the cabin side, 24 on the engine side.
My ground cable runs from the - side of the battery to a point on the cage
(I'm in a Glastar), from the cage to the back-side of the ground tab block.
On the engine side of the firewall, I have a ground strap from the 24 tab
side to the engine block.
In terms of all the deivices in the airplane, everything gets its own ground
so every switch, device, etc that needs a ground, gets its own ground on the
ground tab. Same is true on the engine side of the firewall. I figured
that each device getting its own ground would eliminate multiple devices
failing because of a fault ground in the event that grounds were
daisy-chained or ganged together.
I don't know if this is in line with what Bob suggests, but in my mind it
seemed reasonable. :-)

I made my own grounding system. If you can find a sheet of brass you can
buy the tabs from Steinair for next to nothing.
I made a 60 tab block for the backside and a 12 (I think) for the front
side.
Yes I have a number of spare tabs but not excessive.

Hi Jerry,
I made an "avionics ground" using the method described in
this PDF:
http://www.aeroelectric.com/articles/Rev11/18Audio_R11.pdf
I also have a 24 tab ground block in the cabin for pretty
much everything. It's getting full. I've got some pictures
and a drawing here:
http://www.rv8.ch/article.php?story=20060301215616213
My system might be different from yours - I'm using a Subaru
and I have my batteries behind the baggage area.

You can't go wrong with the 24/48 firewall kit. I did not need 24 on the
engine side of the firewall but you will need a few and you need lots on the
aft side. I used 48 and then started doubling up a few. No problem doing
that just more work. Larry

Dead on . . .
Can't have a ground loop when there are no loops.
Can't have a poor quality ground do to lack of surface
preparation and/or loss of threaded fastener tension.
Can't have a single fastener drop the grounds for multiple
systems.

check out the revision 11 additions to system ground diagrams
in Z-15 and the discussion about an avionics/panel ground in
Chapter 18. See photos on fabricating your own panel ground
bus in the photos file at:
http://www.aeroelectric.com/Pictures/Grounding
Note, panel/avionics grounds should be used only for instrument
panel mounted stuff . . . don't ground any other airframe systems
to this bus. Extend this bus to the firewall ground by either one
"chubby" wire (10AWG or so) or multiple 20AWG wires as suggested
in the Z-figures.

This is exactly what I did also. I got the brass from McMter Carr
(www.mcmaster.com). Hobby shops also probably also carry it, but be
sure to get a heavy gauge thickness - not thin shim stock.

There are a lot of ingredients in the recipe for success
not the least of which is how 'smart' the laptop's charger
is. I had a laptop years ago that ate batteries but for the
most part, we've had good success for probably 3 or 4 dual-use
laptops where they're plugged into AC mains most of the time.
The easiest way to kill a perfectly good battery is to
overcharge it. I suspect this as a strong hypothesis for
your own experience. None of the laptops I've owned ever
cautioned against extended operation under AC mains power.
I suspect this is because the designers believed that their
particular battery maintenance protocols were optimized for
this kind of service.

I have an Aviation Communications AC-6PA intercom, but
the harness is now mostly spaghetti so I need to
rewire it (for an experimental). Does anyone have a
wiring diagram for this or a similar model, or a link
to how to test/guess without harming anything? (I
found the 170B diagram on aeroelectric.com quite
helpful.)
Thanks in advance-
Wes
