Would a crimped splice also be okay? I already bought some and don't want to also
buy the heat gun needed to use the solder splice you mentioned if I can avoid
it.

| Subject: | Re: 24v aux power port? |
The Cessna I've had for 15 years has a 24v power jack and I've never had a problem
with passengers connecting anything to it. Partly because I don't let my passengers
connect things to my airplane without asking first (and if they didn't
ask, they deserve what they get). :D And secondly, it's already in use.
So can someone second that there is no difference in the construction of one of
these 12v connectors?

How about installing two DC power outlets, one for 24 volts and one for 12 volts? One like this can be used for 24 volts without the danger of a 12 volt device being plugged into it. http://www.mouser.com/ProductDetail/Switchcraft/712A/?qs=sGAEpiMZZMv1TUPJeFpwbvDLoO7VplWmGzPCelncVas%3d
A DC to DC converter can supply 12 volts to the other cigarette lighter type outlet. http://www.ebay.com/itm/24V-Step-Down-to-12V-DC-DC-Converter-Regulator-20A-240W-Converter-USA-Shipping-/121289155547?pt=LH_DefaultDomain_0&hash=item1c3d65a3db

This problem has been managed with crimped splices
for decades . . .
http://tinyurl.com/l67uj8h
You can bring multiple wires into any of the
PIDG (or equivalent) devices as long as the
devices is sized for cross section of copper
in the proposed joining . . .
Soldering them together under a heat-shrink
cover is equally functional . . .

Label it clearly, make sure it's isolated from any other circuit, and
control what your passengers bring into the aircraft.

If you only want to do one or two crimps .. and do not want to hand down a
perfectly good heat gun to your grand children .. only used once .. :-)
Just heat it up using a lighter .... it will crimp fine with just the heat
from the flame .. just do not put it into the flame !!

A good way is to practice on some scrap pieces of same material before
going on with the real stuff.
Been there myself. Works on almost anything but especially electronic
stuff cables connectors and such.
When you start it looks like "Hey! What could possibly go wrong!?" After
it's more like "everything went (/"&"%-ng wrong"
Cheers!

Switch?

It's an understandably mixed bag for terminology . . .
Forces exerted by drag go up with square of speed so extending
these little critters into the slip stream at cruise will, no
doubt, exert substantial drag during a flight condition where
lift is at maximum (attack angle low).
During approach to landing, airspeed is perhaps 1/3 that of
high speed descent and the wing is working harder at a
higher attack angle.
The only two times I experienced the behavior of this system
was in Mooney's on approach. Once at Kerrville with a factory
test pilot, the other at Wichita in a friend's airplane. In
both cases I was encouraged to toggle the boards up and down
while watching the effects on rate of descent.
The extending the boards had no observable effects on airspeed
or angle of attack but a profound effect on rate of descent.
Hence they were behaving more as modifiers of lift
than as dissipators of kinetic energy . . . i.e. spoilers
I think there is a valid argument to be made for both behaviors
dependent upon the flight airplane's flight condition.
I was at Cessna in their Tech Pubs department when Bill Thompson
(founder of Precise Flight) was head of flight test. He was
partners with my teacher, friend and mentor of more than 40 years
(Ken Razak) in a nice old C-195. It was my offer to install a
Cessna surplus ADF-300 in the 195 that introduced me to Ken
and launched a career very rich in opportunities to learn.
I owe much to those two gentlemen . . .
Bob . . .

To answer your original question, the lighter jack you mentioned should
work with 24V. Typically voltage ratings are either (1) for safety
reasons, where it is easy to stick a finger in and get a shock, or (2) for
dielectric withstanding/arcing. 12 to 24V isn't enough to trigger either
restriction. While alternatives have been suggested, fuse it properly and
you'll be fine.
