 Posted: Tue May 09, 2017 5:59 pm Post subject: Powering up new panel in my RV9a |
 |
|
Stein Air built me a very nice Garmin G3X panel for my RV9. I am in the
process of installing it.
My preference is to incrementally test and verify the various circuits as I
connect them.
I have installed a battery box for an Odyssey PC680. It will be several
months before I complete the installation, and would prefer to use a fresh
one for final check out, engine starting, and flight testing.
While the plane is on the ground during testing I was thinking of using a
regular 12v auto battery with battery minder attached to it.
Bob - do you see any potential issues with this?

Double check battery polarity to prevent damaging avionics.

That's a good way to do it. I've always discouraged
builders from buying a 'flight battery' until the
days before first flight. Before that time, a garden
tractor battery from WalMart et. als. will let you do
your development/testing work.
Years ago, I used to sell a 13.8v bench supply . . . I
think it was rated at about 25 amps. If memory serves,
we used to get $140 for them. These were recommended
as a 'plug in battery' . . . just wire this puppy to the
airplane's battery contactor. Nowadays, there are even
better bargains out there . . . here's one:
http://tinyurl.com/54fk
This thing puts out enough snort to run the whole
airplane. You could put on your white scarf, turn
out the shop lights and sit in the cockpit with the
whole panel lit up while playing engine noises on the
.mp3 player.
Before that time, it's useful to pull all the fuses
out of the panel for installation one-at-a-time as
individual systems are fired up for the first time.
In any case, buying/installing the flight battery for your
airplane should be a ceremonial event . . . like
breaking the bottle of champaign on the bow of a
ready to launch ship.

Thanks Bob.
I bought one of these. It was about the same price as a battery.

yep . . . better yet, it won't go sour sitting
on the shelf!
Batteries are like house plants. You gotta 'tend' them
whether in-service or not. I just pitched a lab
battery last week that I'd allowed to self-discharge
and degrade to salvage value.
I'm upgrading my battery storage area to facilitate
maintenance on all the batteries in the shop . . .
a feature I did not implement immediately after my
move from Wichita to the Kansas hinterlands.
With the addition of suitable connectors and controls,
power supplies of this nature can be configured
to serve as ground power carts with no wheels . . .
since they're not beefy enough to crank an engine.
But they pretty much run everything else.
The only caution is to not use these things to
charge a badly discharged ship's battery. It's
okay to have this power supply on line with
a battery as long as the battery is pretty
strong. This would be useful for running hi-
inrush, intermittent loads like landing gear pump
motors.
But for the most part, these supplies are happiest
doing the whole job all by themselves.
