I did not intend to knock the company around, as I personally don't feel
there is much of a problem here. Others may think as they wish, of course.
There are a lot of these in use, and there are bound to be some failures.
Imagine how many would be failing if there were a billion of them sold. A
percentage of units failing would be a more meaningful number to look at.
The second failed unit I worked on was not from a Europa, but another
well-known kit manufacturer with many many hours on the clock. I still
consider my out-of-box failure (shipped in late 2001) an outlier of sorts,
and that most of these work fine at installation. EVERYTHING runs down or
wears out eventually.. Its just a question of how long.

Hi Fred
"...Bingo!...(?)...@ RR I heard someone recommend
shielding ALL wires...(?) "
Not a great idea to shield power
cable for Kunzleman strobes, thats for sure. It brought a tremendous
amount of noise into the radios! Twisted pair is the secret. Here was
effort:

Ron...now that IS a surprise...Kunzleman ships w/ shielded cable, and
I would have thought that strobe wiring would be the one place where
shielding would be essential...I understand proper grounding of
shielded cable is critical, but my thoughts on all things electrical
however should be taken w/ many grains of salt, as my knowledge could
fit on the head of a pin.

Hi Fred
On the Kunzleman strobes shielded wire should be used for the high voltage output
of the power supply.
I tried using shielded wire for the supply side and it caused major problems. As
a matter of fact untwisted wires for the supply side worked better than the
shielded wire (but still poor).
Here's what worked for us:

Ron and Fred and others:
It has been my experience that twisted pairs and all power wires be
separated from com wiring. My basic plan is always to put power down
the passenger side and com signal down the pilot side. No short cuts
and believe it or not I have been lucky for years now. Behind the panel
I even go to the extent of not allowing a power bundle and ground pairs
to pass within inches of the back of the radio or intercom. All it
takes is one bad apple appliance to cause trouble. I had Homer Bakers
panel in rebuild and I ended up shielding everything just for sport.
The noise was coming from the engine sensor leads going to the Blue
Mountain, acting as an antenna from the voltage regulator of the
computer. Go figure. Following this simple technique of separation and
clearance has allowed me to be trouble free in my panel noise.
Good job of sticking to it and tracking down Ron.

i am on the point of changing my instrument panel from a silly old
homemade EFIS to a Dynon D100 box. I have the room; the wiring is MUCH
easier; the job will close much earlier.....
If any one on list has used this box, I would appreciate any comment
PLUS is there any complaint of heat dissipation - about the only point left
to contemplate so far?
Cheers,
Ferg
