Do we know exactly where the smoke was coming from?
Is the relay visibly damaged or the regulator?
The fact that your voltage started to come up when
you re-energized the alternator suggests that the
rectifier-regulator was not killed. Try making a
hard connection to bypass the control relay and
do a ground run to see if the bus voltage comes
up . . . do this with a fully charged battery
so that you don't have to wait for the alternator
to top off the battery.
If I'm understanding your words, the relay is what
failed. I'd like to get my hands on it for examination.
I'd be pleased to send you a replacement but I suspect
you can find one much faster locally.

I will be installing the Artex ME406 w/110-773 whip antenna. It broadcasts
on 121.5 and 406 Mhz.
I am installing it in an E-glass plane. What is the mimimum ground plane
that will work. The instructions are suggesting that the ground plane
radius should be 24" in all directions! The plane is not 4' wide at any
point in the fuselage!!?
I really don't have much room for this install since I am trying to keep all
the antennas inside the plane.
Does anyone have a suggestion as to how I can install this antenna or make a
half wave that doesn't require a ground plane?

The ground plane can curve - to some extent following the contour of the
fuse. I imagine that if the radiator is in the middle of the fuse and the
ground plane wraps very far up the sides, performance will suffer to some
extent, though performance may still be acceptable to you.
What type of antenna have other builders used? External?
Is it possible to install the antenna in the fin? Is it e-glass also?
You may be able to install an antenna that looks electrically like a 1/4
wave dipole, but is more physically compact in length (height). How tall
is the fin?

| Subject: | "Shuntless" Ammeter in Diagram Z-16 |
Hello,
I am building a Zenith CH701 with a Rotax 912ULS engine. I am using the Z-16 diagram as reference for my electrical system. I purchased a VDO ammeter (no shunt required) from Aircraft Spruce: http://www.aircraftspruce.com/catalog/inpages/vdoammeter.php
I am wondering how I can incorporate this into the electrical system to monitor
battery output/discharge. Can the ammeter simply be put in between the battery
and battery contactor?
Thanks,
Dan Ginty

The ground plane radials need to be 24" long but not necessarily
flat. The easiest way to make this happen is to mount a "patch"
of brass sheet (shim stock, sheet stock from hobby shop) about
3" diameter on the inside surface of the skin centered on your
antenna location. Copper foil is nice stuff to make radials out
of but copper wire will work too. Further, it's easier to find
(a 6 foot piece of 12x2 Romex with ground will yield 18' total
of 12AWG solid wire). Solder as many 23" pieces of 12AWG
wire as you are willing to mess with to the edge of your
brass grounding pad at the base of the antenna. Route radials
away from antenna following inside contours of skin. Stick each
radial to the skin with patches of BID glass and 5 minute epoxy.
4 radials is about the minimum, return on investment of time
beyond 8 radials is poor.
Recommend you stay with the supplied antenna . . . it may have
features that enhance its two-frequency performance.
Bob . . .

I found it in 'the book' and I've posted it at:

Never mind. I just reviewed Section 7 and found what I was looking for. I'll try
and rearrange the system to the 'classic battery ammeter wiring' shown in Figure
7-11. Thanks anyway.

Tim, How can you have a discussion of electricity without paying homage to
Joseph Lucas, the discoverer of the short circuit? :-)
