Exactly. There's another important component to this
discussion. The List is not just a place to ask, "what's
2 + 3 and where do I buy some 3's?" It's a classroom
where about 1400 individuals watch the proceedings and
take away buckets of simple-ideas along with a few
recipes for their utilization.
Whether we're cooking stuff up on the stove, writing
software, or configuring an electrical system, the
elegant solution will be elusive unless the 'chef'
understands exactly how all the ingredients behave
as individual components and then in combination with
each other.
In this class room environment there is, and should
be, a high probability that any questioner may be
asked to stand up in front of the class and defend
his/her recipe for success. My bosses called this
process preliminary, critical, and qualification
design review. A means by which ideas could oscillate between
any constellation of extremes as collegial argument
deduces the elegant, lowest risk way to meet customer
design goals.
There is a risk that some questioner will feel picked
on or belittled. I'm probably as guilty as
any for not always making sure that the questioner
understands this process along with his own, important
role in this sharing of knowledge.
Mr. Ryan has states some ideas and goals and he
has been asked to share his supporting thought processes.
Of course, nobody will be insulted or even disappointed
if he declines. At the same time, everyone
interested in the conversation may harvest and
exploit any number of simple-ideas supported with
examples of how they fit together.

Subject: | Re: alternator / generator |
Hi
I have a Rotax 914 with dual Lithium batteries and instead of the Rotax Ducati
regulator use the Schicke GR6 regulator as it a more robust device. My aircraft
French DynAero MCR-4S is advanced avionically and uses as it base Bob's infamous
architecture. I do not have the external alternator as it is unnecessary
(for me).
On the primary bus I use a Vertical Power VP-X (serial connect for laptop control)
and good old automotive fuses on the endurance bus. The VP-X controls the
relay for alternator disconnect.
This is a very stable environment with no problems of any sort. Happy to share
my schematics.
Cheers Peter

Subject: | Slick magneto switch shield ground |
I am about to connect the magneto switch wires for Slick mags on a Lycoming O320
engine. I have the Z-34 set-up of two (2-3) magneto switches and a push button
for the starter. Note 3 for Z34 advises grounding the shield to engine ground
at the mag end. On a previous post I found this:
I recommend each mag switch get grounded through the shield
of the p-lead where only the mag end of the p-lead shield
goes to the crankcase or other handy fastener on the engine.
Bob . . .
On the mag case an inch from the P lead post there is a handy #8 screw labelled
GND. The case is intimately attached to the engine. Can this GND screw be the
handy fastener on the engine where the P lead shield is grounded when wiring
a mag switch per Z34?
On the switch end, the same P lead shield gets attached to terminal 3 of the switch,
right?

The mag pictured is not mine but is like the one I have and is for illustration
only. No advertisement intended.

Yes . . . or to any other 'handy' ground
to crankcase . . . doesn't have to be on
the mag nor is it prohibited to extend the
shield ground with a pig-tail long enough
to find a more remote ground. But it looks
like your best option is nicely located.

Yes . . .
