Esco, your schematic shows 4 wires going from the MZ-30L generator to the aircraft
electrical system.
The MZ-30L installation manual shows ZERO wires going from the MZ-30L generator
to the aircraft electrical system.
All of the wires from the MZ-30L generator must ONLY go to the regulator. None
go to the aircraft.
Only the regulator has wires going to the aircraft electrical system. The generator
puts out 3 phase AC.
Therefore it can NOT be connected directly to the aircraft DC electrical system.
The generator can only be connected to the rectifier / regulator.

Joe: thank you very much!
You're absolutely correct.
I read the installation manual, specifically "2.2. Minimum Installation / Required
Connections" several times... and still misunderstood. I'll make the updates
tonight!

Thank you so much for the offer sir. BTW, nice
looking assembly. SMA connectors? What does it do?
I did a surface mount ECB and already have the
boards. However, while resolving some issues with
solder paste dispensing I had an epiphany . . .
I'm not at the stage of my 'career' to be
launching a project to be manufactured in
my shops.
Decided to convert it to thru-hole so that
I might offer kits . . . and perhaps get
some local kids interested in learning how
to put such things together. I've published
the 'plan-b' details in another posting. I'll
comb it for errors one more time and get
boards on order. Should be here Friday.
I'll also get an order in to Digikey for
parts compliment.
If you'd care to proof the layout yourself,
your input would be truly appreciated.
It's a bit risky to proof one's personal
work product . . . but then I'm probably
not telling you anything you don't already
know!
Yeah, about that 1206 footprint . . . that's
been my favorite choice for hand assembly for
the past 20 years or so!

I've published the ECB layout and assy data at
https://tinyurl.com/ytdg9ehf
Any any assistance in proofing the layout to the
schematic would be appreciated. Will order boards
late tonight.
Got an order about ready to ship to Digikey for
parts.
We might get this project into smoke-test yet!

Bob,
Still interested in being a beta-tester. With the through-hole redesign I c
an probably competently assemble it myself! Even better for my use case if t
he low voltage warning light/LED option is included.

You're at the top of the list. We'll assemble the
first 'batch' here for testing. The lv warning
board gets trimmed off . . . that's a separate
project that's still under cultivation. But you
can have one of those too once they're ready
for prime time.

Bob, The unit displayed is an RF/audio probe for signal tracing. this feeds an
amplifier. Yes, SMA connectors. It makes a nice compact unit using RG 174 as a
lead. The probe is powered from the amp.
I am not sure how this is going to get displayed as I rarely use quotes or even
reply.
