Interesting. I plan a 75W taxi light and a 75W landing light on each
gear door, so 2 light per side, 4 total
Will the added weight on the doors impact their remaining closed under air
loads? 'Twas Lancair's concern Wendell Durr

| Subject: | cycling voltmeter and ammeter |
--> AeroElectric-List message posted by: N223RV@aol.com
have about 16 hours on my RV-4 and have a question.=A0 My voltmeter and
ammeter cycle between 13-14.5 V on the voltmeter and between 5-10 amps every
1/2 second or so.=A0 The volt meter rapidly rises from 13 volts to 14.5 volts
and back almost like the voltage is rising, gets too high, cuts out, drops
below 13 volts, kicks back in, rises to 14.5 volts, cuts out......=A0 It just
rapidly cycles up and down.=A0 I have tried adjusting the voltage regulator
lower but does not seem to help the cycling.....
I have a 35 amp Van's supplied alternator, a Van's supplied $35ish voltage
regulator, and an Aeroelectric overvoltage protection device.=A0 This issue
does not seem to cause any problems, but it does not seem right.=A0
Last night I turned on all my electrical accessories and it seemed to steady
out at about 13 V, but if I turn off just a couple of items, it goes right
back to cycling.=A0 I don't understand what is going on or if it is an issue,
but it just does not seem right. Does anyone have any ideas on what to check?
Thanks

They are on the outer gear door which is directly connected to the
strut, so I think they will be alright....we'll see.

--> AeroElectric-List message posted by: Richard Dudley <rhdudley@att.net>
Bob,
I like the idea of having a ground power jack for the reasons you list
in your paper. I have ordered the parts to install one.
In re-reviewing the schematic (Fig. 3) I am having a problem
understanding how the ground power contactor can release when the
external power is removed. It seems to me that, since it is connected to
the aircraft battery positive, that contactor will remain energized
after the external power is removed; with the only recourse being to
pull the circuit breaker to unlatch the contactor.
What am I missing?
Regards,
Richard Dudley

Rick,
NARCO now does all their own repairs - no dealer repairs anymore, so
you're stuck with them unless
you can find a avionics repair shop that has some old ones laying
around.......

I need to replace one of the little plastic gears in the
frequency
selector mechanism on a Narco Com 120.I called the factory
and they want
me to ship them the radio and $400 or $500.
It's obviously not worth spending that much on a 20 year old
radio. Is
there another source for these gears?

Rick,
A mate of mine back in Australia had the same problem with his Narco transponder.
He was quoted same, except US$500 is $1000 to an Australian..
Solution: He made an aluminium version of the gear on his lathe, installed it,
and is living happily ever after. NB: He had to synchronise the actual frequency
with the number on the dial (Note: It was only one XPDR dial of the four).
You could probably get an Avionics shop to install your own gear and bench synchronise.
The tech wont look twice when he sees the stripped plastic version he's
replacing. Personally, if your not breaking a warranty seal on the old box,
I'd do it mys.... (Ooops, can I say that?)

I don't know about the gears, but I've seen Com 120s on Ebay for relatively cheap
:
http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=2401916981&category=26436
Certainly better than handing over a fistful of cash to Narco or redoing your panel
around something else....

Might check to see if the older non-approved COMs have the same gears.

Bob,
I believe that I have found the answer to my own question. The symbol
that I took as a circuit breaker is a switch breaker. Then the operating
procedure would be to connect the external power which could be
confirmed by the push-to-test light. The switch breaker would have
control of the contactor and would have to be switched off at the end of
the transfer to avoid the battery holding the contactor closed.
Regards,
Richard Dudley

You guys sure are a helpful lot :
)
Besides the answers I got here on the list, I got several more emails at
home with suggestions.
I was thinking about making an aluminum replacement on a lathe, but went
out to the local avionics shop and was able to buy a "core" with a
decent set of gears in it. I went through 3 radios before I found one
that didn't have too much damage on the same gear. The one I ended up
buying had a little crack already starting, but I laid a bead of epoxy
alongside the gear and bonded it to the aluminum hub it is pressed onto.
It works great, hopefully it will KEEP working.
Thanks,
Rick Pitcher

The Chief Aircraft catalog has 3 different types of coaxial cable: RG-58 (50 ohm),
RG-142 (low loss for DME/TPX/GPS) and RG-400(low loss for GPS). I have used
only the multi-stranded RG58 in my homebuilt for all the radios, not knowing
about the other two. Why the other two???

I've done that in the past, and it's seemed to work fine for me. But
someone who *says* that they know RF tells me that you loose a lot of
energy out the angle unless it's a super special very expensive right angle
that has a little horseshoe magnet in it. Any truth to that?
