Listers,
With a little more diligence, I've managed to find the following link. No a lot
of info on it though.
http://www.delphisecure2.com/site/home/HomeMain.asp
Choose AUTO FUSE SERIES from the Search Products by Family Name listing on the
left hand side of the page. Part numbers 10719123 & 10719136 may be what is needed???
I've sent an inquiry to Packard Delphi for more info.

I've seen the Bussmann info on those fuse holders too and thought they
looked nice. Recently, I saw them in a Watek, Inc. catalogue and they
were priced at $32.04 (Qty 1-9), $27.24 (10-49), $24.03 (50-99). They
sell the terminals too. I'd like one for a 4WD vehicle I'm working on.
If there is enough interest, I'd be willing to order a group of them
along with the terminals and make them available to others. The one
they listed in the catalogue is a 20 position dual bus unit. One input
stud feeds 14 of the positions and the other input stud feeds the other
6 positions.

The parts business I used to manage from my facilities sorta
exploded a couple of years ago and became a third full-time
job. I sold it to B&C in Newton.
>Any assistance you or others may be able to offer would be much

I've forwarded a copy of your note and my reply to
Todd at B&C with my recommendation that he look into this
variation on the fuseblock concept as a good candidate for
enhancing his level of service to the OBAM aircraft community.
I was not aware of this new offering. Past versions of rear-wired
fuseblocks were not very useful in the one-wire-at-a-time
fabrication mode we use on our airplanes.
Thank you for bringing this to my attention!

If you have a metal airplane, remotely mounted items like
light fixtures, pitot tube heaters, strobe power supplies,
etc can be grounded locally to the airframe.
>In the Aeroflash FAQ ( http://www.aeroflash.com/faq.html ) it says to use

It isn't always beneficial . . . for example, it's possible, nay
even probable that if you simply ran a twisted trio of wires from
your power supply to strobe heads, you will experience no adverse
conditions. Having said that, given that most strobe systems purchased
as a kit come with a shielded trio, why not use it? Similarly, it's
no big deal to purchase the shielded trio if it didn't come with
the kit.
This is an important point to remember about noise mitigation.
There are some things we can do that always reduce noise problems,
others that help most of the time, still others that help some of
the time, and probably more that almost never make a difference.
The trick is to put all of the techniques we know about into
two piles (1) hard/expensive and (2) easy/cheap. Doing all the
easy/cheap things is simply good insurance against having to
rework or troubleshoot a problem later. A shielded trio between
the strobe heads and power supply fall in the easy/cheap category.
What is it your grandfather said to you as a kid? "If you haven't
got time to do it right the first time, where will you find the
time to do it over?" Well, my grandfather never said that to me
that I can recall . . . but I betcha he would have if he came out
to my garage, and saw me thrashing around in a big pile of parts
that was to become an airplane in a year or two.

Is the Van's instrument a battery ammeter (-zero+)? If so,
and assuming you want it to read like a battery ammeter, your
system will have to be wired like a C-172 and bring the alternator
b-lead into the bus instead of tying to the starter contactor
on the firewall. You can use these archaic instruments as
an alternator loadmeter by installing the shunt in the b-lead
as shown in the z-drawings . . . it just never gives a reading
in the minus territory . . .

I was going to suggest that but thought I'd let him down easy.
Now that you went and done it anyhow, I'll have to agree that
if it were my airplane, I'd install an instrument/shunt combination
that was sized to the task.

Actually, it will probably do it every time the engine is
started and the alternator comes on line to recharge the battery.
Pointer instruments aren't all that fragile. I've see situations
where an instrument took a 5x momentary hit routinely with
no ill effects.

Bob-
I received the replacement processor from Ian at Microair one week from
his offering to send it- pretty good from Oz to TN it would seem! I was
able to borrow the proper removal tool and replacement was simple (talk
about clever packaging!!). Unfortunately, it was not the problem and
the radio behaves the same as before. I have e-mailed Microair
requesting further guidance and will let y'all know what happens...

These devices look like what I was talking about except that they require me to
design and build a circuit to display the current flow. Sadly, I am not able to
do that. What I need is something I can wire directly to a meter. That's about
the extent of my circuitry skills.

Let's see if B&C is going to stock them and how good of a price they are

Hi Mike and all,
Mike, many, many, many ... thanks for your answer.
I had just heard about the "Ground loops", now, I know all !!!
I think (I hope!) I have understood the philosophy of "single not ground"and I
will try to respect it !
I think too that the layout I plan and dscribe in my first message, is near the
"radial grounds" concept you describe. I am lucky!
Please, allow me two questions:
(1) I will use a MED 80 for the monitoring of my ROTAX 912 ( http://www.bwavio.com/manuali/man_med_80_usa.pdf ). It collect informations from probes on the engine (witch certainly have engine-ground) and have its own electrical feed. If I have well understand, I have to wire the MED 80 ground up to engine ground and keep its frame isolated with the instrument panel. Am I right ?
(2) I will use the diagram recommended by Bob for the ignition blocks and the
starter commands with 2 swithes S700 2-5. The two "put to ground "wires, killers
of ignition will be shielded. Should they be connected only to the "engine
ground" or also to the ` instrument panel ground " (as ROTAX said) and might
have a "ground loop" ?

Subject: | Battery Contactor |
--> AeroElectric-List message posted by: Larry <larry@grrok.com>
How can I verify that the battery contactors have closed in a dual battery
system, Figure Z-30. It is easy to verify that the contactor coils are
energized but system voltage will be established as soon as the one of the
two battery contactors close. This condition can be detected during
preflight by switching: Main Battery, Both, Aux Battery but I think there
has to be a more elegant method.

Bob N.
Thank you for your reply and for passing this info on to B&C. Hope they
oblige. Could have knocked me over with a feather when you said you
hadn't heard of them!!
Dave and William
I agree we should wait to see what B&C does. I have to order other
items from them in the near future so it would be more convenient for me
if the fuse blocks will be available through them.
However if this does not eventuate Dave, I certainly would appreciate
the insurance of having you as a stand-by if you don't mind. Thank you
too for posting the cost of these items as I was unaware or this aspect
before.
Cheers

Bob,
I'm building a europa with Rotax 914. The plan is to use Z-13 with a SD20 for
one alternator and the Rotax alt for the other. Will two alternators work together
to charge the battery? Neither one has the capacity to keep up, but the
two together do.
Thanks
Jim Butcher Europa A185

Now THAT could be a solution. It takes a lot of panel space, but that might be
negotiable. I checked the specs for the AMP25 and AMP200 and figured they would
need some supporting circuitry. I was hoping I could maybe connect it to the
meter I have after removing the shunt and get the accuracy I need (vaguely
accurate, charge and discharge magnitudes). Guess not. The CS50P would "plug
and play" and I could open up the panel hole to accept it.
Thanks a million for the heads up ... Jim S.
