According to the last page of the pdf (link provided above by Paul), the flasher
will work with LEDs if a 75 ohm, 5 watt resistor is connected in parallel with
each LED light.

Thanks Joe
All I had to do was to mentally remove the bridge diode and the need
becomes obvious. I now believe I have enough information to proceed.

Joe,
THANKS...this is very good information!!!

I have one on order...now. Dynon has a nice looking knob.

Is your friend running two fuses for the power supply for the Dynon SV?
I read that the system is designed for two power source wires and ground
wires because the max load that the D-Sub pin can handle is only about 4
amps so they ran two power wires. I am running two 5 amp circuit breakers.
I have not powered up the system...hopefully it will not let any smoke out
of the wires.
Page 4-9
Power Input
SkyView displays have a primary power input that is compatible with 12 volt
and 24 volt
systems (10 to 30 volts DC). There are two unterminated solid red primary
power input wires
(to reduce current loading in each wire-these are not for redundancy and
both must be
connected to the same power source) and two unterminated solid black primary
ground wires.
Page 1-7
Power Consumption
Table 2 contains SkyView displays and devices that are powered by SkyView
displays. 5A circuit
protection is recommended for SkyView displays in common configurations; 5A
is the smallest
circuit breaker that is commonly available in certified versions.
..
Cheers!!!

Skyview Brightness a
Bill, your reasoning is correct. But do NOT use a rheostat because it has
low resistance and will draw too much current. Use a 5K or 10K POT or
whatever Dynon recommends. The pot will only draw a couple of milliamps.
You could get 12 volts from SV-EMS-220 pin 15 or any convenient place. Pin
15 probably has internal over-current protection. The SkyView fuse can be
increased in size from 5 to 7.5 amps, not because of the pot, but because a
5 amp fuse can blow under certain conditions. A friend of mine was on a
long cross country when his SkyView display went dark because the 5 amp fuse
blew. He replaced the fuse in flight, and the replacement fuse also blew.
Luckily it was a daytime VFR flight. The reason the fuse blew was that,
prior to the flight, he had been running the SkyView from its backup battery
and ran it down. While on the cross country flight, the SkyView was drawing
maximum current to both operate the EFIS and to charge the backup battery.
He called Dy!
non because he thought the SkyView was defective. They recommended that he
power the SkyView through a 7.5 amp fuse. He did and no more problems. If
your plane has circuit breakers, not fuses, a 5 amp breaker will probably be
adequate because circuit breakers are slower to trip than fuses.

Okay the original diagram was from a maintenance manual, here's one from th
e POH
I think the big diode in the B line is used to limit / protect the alternat
or line (aka no circuit breaker) but now what the heck is the power relay
circuit at the bottom ???
And the diode is still in the ground power, Maybe to protect from reverse p
olarity ??

At 12:33 PM 2/4/2017, you wrote:
Why is this diode in the Alternator B line ?
Is it old thinking from way back in the day and old tech maybe to protect t
he older alternators ?
What is the source of this drawing? This diode MAY
have been offered as an alternative to b-lead protection
for failure/crash faults on the line to the alternator.
but it's in error as to how the starter contactor is
wired. There's also a curious diode in the ground power
contactor wiring.
This drawing has the 'smell' of having been copied from
some more credible source as a 'simplified' wiring diagram
not unlike those in the Cessna Pilot Handbooks of yesteryear.
A guy named C.E. Fraley used to sit right behind me in Cessna's
Tech Pubs department. He used to do all of the POH for the Pawnee
Plant. On several occasions I was asked to vet figures that he
distilled from the production wiring documents.
[Emacs!]
The simplification process needs to be conducted carefully
lest errors creep in. I suspect that the drawing you cite
may have fallen victim to errors in transcription.

No, my friend's SkyView is powered by only one fuse.
And you should only use ONE circuit breaker.
The SkyView manual states, "same power source". That means one breaker or fuse.
But connect 2 wires to the one breaker to power the SkyView.

FWIW, I have the Belite RADIANT dual fuel gauge in my GlaStar and I love
it. I'm using it with the capacitance senders that came with the plane
and it works great. The gauge is very readable, very light, and was easy
to install and configure.

My response.... . "Hmmmmmm"
Perhaps more appropriate... !!! DOH!!! (Homer Simpson emoticon added for
dramatic emphasis)
I guess I kinda interpreted the "same power source" to be the same battery
/alternator....
Hmmmmmm.... Grrrrr....
