relay
The Aeroled units with wig wag were an additional $100 each. It was a lot cheaper
to buy a simple flasher unit. I have a light in each wing tip. The wiring is
also easier with the flasher unit behind the panel. The Aeroled units need to
be connect by a few wires that would have to run tip to tip.

Thanks

The cheap NAPA relay will not work to wig-wag HID's even if you do heat them up
manually.
I use this solid state wig-wagger and it works great with em!

Jan
Thanks so much, I think the diagram you provided is accurate, the
replacement part number for the SCR (2N6504) help verifying that these are
SCR'S. by looking at your diagram I was able to understand the principal of
operation of the charger. The two SCRs are used to connect to ground each
one of the G terminals during its negative part of the cycle making
it referenced to ground so the other G terminal can charge the battery thru
the in line diode. (the G leads coming from the engine are not referenced t
o
ground otherwise).
With regards to my charging problem, the way I read the diagram is the
charge light on/off control is related only to the existing of AC energy
between the two G terminals, not to anything else, it=92s a bit surprising.
My
understanding of the charge light logic did not help me at all to Identify
the source of the incorrect indication problem I am facing with.
Bob,
I suggest that you replace the diagram currently published on your web sit
e
with the one Jan has provided
Thanks and regards

| Subject: | Report on New Power Supply |
A few weeks ago I reported that I had bought this 12 volt power supply:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=250852141183
I wanted it to power my instrument panel while doing navigation data
updates, cycling the wing flaps, and other tasks that would otherwise
take power from the airplane's battery. I have one that appeared
similar to this one that works perfectly.
However, the new one seems pretty close to useless for my needs. If I
adjust the output voltage higher than about 12.4 volts DC, the power
supply goes into overload and makes a quiet snapping sound about once
per second and the output amps go to zero (while it's connected to my
airplane's battery).
The literature claims the output voltage is adjustable from 10.8 to 13.2
volts and that the input voltage is from 100 to 264 VAC. However, the
one I received is labeled 176 - 264 volts AC. My guess is that since my
input is 120 volts, the power supply cannot achieve the stated
performance.
I only paid $15 for it, including shipping, so I'm not all that unhappy.
I'm sure I'll find a use for it somewhere. I just wanted to pass along
that the power supply I received doesn't seem to be suitable for 12 volt
airplanes. I could complain to the seller, but when I emailed them to
ask how to connect it, since it came without instructions, my emails was
never answered and it's now worth my time to fight for $15.
I might look at battery maintainers at Wal Mart instead. Since I'm done
building, I don't ground test heavy loads (like raising and lowering the
landing gear) that often. A battery maintainer is probably all I need
anyway.

Good idea sir. I'll do it right now.

Interestingly, if you look closely at the photo on the eBay listing you can see
printed on the top of the supply "AC 176-264V". Not that anyone would notice
that when bidding...
You should at least give feedback to eBay about this. How many others will purchase
this supply just like you did and discover the same thing as you did?
