Subject: | Re: Blue Mountain EFIS |
I have 4 BMA Efis's and 2 autopilots in 2 different planes. Have had them for over
4 years and 500 hrs now. My experience with service and support has been good.
Depending on the Generation of EFIS it may or may not be the right one for you.
It also depends on what you want it to do.
If you are going to use a Garmin 430 or 530 or an autopilot other than BMA I would
not get a BMA EFIS especially if it is a pre gen 4 EFIS and even then I would
be hesitant. They work great with an SL 30.
Also the pre gen 4 units will never be upgradable to the features of the generation
4 units so what you get is what you will have. I enjoy flying my Gen 1 EFIS
1 but it just cant compare to my Gen 4 Sport in features and function.
Support right now for the pre gen 4 units is slow but improving.
BMA had a real nightmare of a launch with the Gen 4 products and appears to have
gotten most (not all) items resolved and hopefully they are now going back and
finishing the un resolved issues with Gen 3.
For me the BMA units did all the things I wanted at the right price and weight.
The delivery delays were not an issue for me but for some they caused considerable
problems and rightfully made a lot of people really angry. Hopefully this
is all in the past.
In any event fully evaluate your needs in an EFIS and what you expect to integrate
it with and then look at all the options available. If the BMA unit fits the
bill and is at a good price I wouldn't hesitate at buying it.

Subject: | Intercom Troubleshooting Help Needed |
I put power to my PS Engineering PM501 intercom last night for the first time and
have a problem that has me at a dead-end. When I powered it up, the fuse blow
immediately. I metered the power lead to ground and got infinite resistance
which tells me that there are no dead shorts in the wiring. I moved the power
circuit to a breaker, just to eliminate the fuse from contention, and it also
popped. Again, no short to ground with the meter. When the unit is switched
off, power can be applied and the breaker will stay latched. This also appears
to tells me that there are no dead shorts in the wiring. It is only when
turned on that it blows. Is this a problem inside the box that I may not be
able to troubleshoot, let alone fix? Any thoughts on what my options are here,
maybe something I have overlooked?

Subject: | Blue Mountain EFIS |
PS- On BMA
They won't let customers back onto their board if you leave bad
feedback, that's why you don't see as much negative reporting. I'm not
sure if they do this actively or not but I have sent them three requests
to get on their web board and they don't reply. I gave up so I don't
know what they would say if I pressured them. Besides, I can only deal
with their attitudes for about five minutes a month and I didn't want to
use up all my gum balls.
Here are some of my more recent stories regarding BMA: I ran into a guy
that had two Blue Mountain EFIS One's in his Harmon Rocket. I was
looking at it and I asked why he also had two Dynon's right next to the
EFIS One. His response to me was the EFIS One would fail all the time
and he would simply pull the unites and send them back every oil change
because the most he would every get out of the unit was about 40 hours.
He has over a year and a half on the units and was going to remove them
this winter. This story was from August 2007.
This is a story from my unit: A BMA EFIS Lite G3. For those of you who
read the BMA web boards there is a story about the altimeter freezing up
in flight. The response is that it can't happen from the BMA folks. I
have had that problem twice and was told over the phone that that can't
happen. So I looked into the mirror and said it must be me and the
altimeter is really working and the ground is just not staying in the
correct spot. (on a serious note, I think the problem is a thermal
issue, I think the unit needs forced air to keep it cool so far that
seems to be working. "I fear the day I have to use it in the clouds
fortunately it only backs up a real EFIS and I added a stem gauge!")
This last story is in progress: I have a coworker who is building an
RV8 fastback with a partner. Both are detailed people are doing a high
end build with all the bells and whistles. Attention to detail is a 10
(I'll send photos). One of them is an EE and knows his way around
electronics at the micro level. They purchased a BMA EFIS one and have
not flown yet. Most of the probes had to have trimmers installed so
they would read accurately throughout the range of operations (I told
you they were detailed). Most of the probes went out of cal out of
nominal rest. I will post when we get to first flight.

Subject: | Removing D-Sub sockets |
Fellow tronners....
Is there a trick to removing D-Sub sockets from the connector?
I have the tool from radio shack (I have actually destroyed three of them) for
the standard sockets. My trouble is that I can't get the tool to go past the
base of the pin to where it would release the 'holding' fingers in the connector
assembly.
It has to be either the tool or my gorilla fisted technique..... every once in
a while, I can wiggle while holding my tongue right, and it'll go in to allow
me to extract the socket.
I have two sockets remaining - I need to get a new tool - is there a better one?
Thanks,
Ralph

Subject: | Intercom Troubleshooting Help Needed |
If you purchased the unit from PS Engineering call them and they should
give you an RMA for a free repair. PSE has always gone over and above
for me both personally and through the shop. If you purchased it second
hand, call them and see what they can do, I'd bet the repair wont be
very much.
Based on your report of the failure, I think the unit has an internal
failure. It doesn't sound like it should be that complicated to repair.
It sounds like a power control problem.

Subject: | Re: Removing D-Sub sockets |
Hi Ralph,
The tool Bob N. shows on his site,
http://aeroelectric.com/articles/D-Sub_Pin/D-Sub_H.jpg
has two ends on it. The red end only goes about 1/2 way around. The
other end goes about 80% of the way around the pin. If your tool
looks like the white end of Bob's picture, it should work without a lot
of force. In fact a delicate touch and patience is necessary. For
some reason, it takes a long time to get the first one or two out, but
once you develop the "feel", they are pretty easy. Force won't work!
The white end is fairly thin and easily bent.
You might want to review Bob's entire procedure at
http://aeroelectric.com/articles/D-Sub_Pin/Pin-Extraction.html
I cursed a lot of pins out using the wrong tool that looked like the
red end before I learned the difference.
Bob W.

Subject: | RE: Terminal Tool TT5000 |
Just received mine, and it works great on 6AWG and some 8AWG. Nicely made
and more compact than I expected. Works well in a vice. Not sure about
holding the frame with a wrench or whatever say in the plane. Haven't used
it yet for the larger battery cables, but looks like it will work up to 1AWG
or so.
The tool's not really designed for 8AWG, but if the ferrule is thick enough
(or I suppose if you add a few wire strands to a 8AWG wire in a 6AWG
terminal ala Bobs soldering technique), it works pretty well. Very nice
circumferential squeeze on the ferrule. I used 6AWG splices to join MAXI
fuse holders (6AWG wire) to 8AWG Tefzel, and it worked fine. No extra wire
strands required.

This statement right here would eliminate the entire company from any
prospect of doing business with me. Read what is written there. Their
Gen 3 products do not work for the purpose intended. Instead of fixing
that product and making things right for their customers, they're busy
working on the next revision...which they subsequently sell to customers
in a broken state. A flight computer for a GA aircraft lives in a very
constrained environment. Temperature ranges and inertial forces have
well defined limits. There is no excuse for a unit not to be tested to
the extent of those limits. The fact that they would repeatedly push
untested products into a potentially life threatening situation says to
me that the company is less than ethical.

Yeah, I was thinking the same thing. I made ultra sure that I had no shorts

Thanks, Bob....
I have two broken white ends - and I didn't push hard at all.
I'm guessing there's a bunch of finesse to get this right. Good part is I only
need to remove two more pins - I was able to get the other eight out.....
I'll order a new tool - and go over the stuff from the aeroelectric website......coupled
with a lot less force.......

Subject: | KX-155 / KT-76A pin wiring & antennas |
I am attempting to install a KX-155 (no GS) and KT-76A in my Zenith CH701 project.
I have the pin wiring diagrams from Bendix/King showing what pin does what,
but I'm confused about the pin labeling.
I referenced Bob's site at http://www.aeroelectric.com/Installation_Data/KX155.pdf and
http://www.aeroelectric.com/Installation_Data/KT76A-76C-78A.pdf
but my unit has a different number of pins. My A1 board is only 15 pins and the
A2 board is 11 pins. How are the pins labeled (1-15, a-z, etc.). Also, what
letters are skipped (I, O)?
Second question: I realize the transponder antenna should not be bundled with
other wires, but is it okay to bundle the COM and NAV antenna cables with other
wires?
Thanks,
Dan Ginty

Yes or even 1/2 watt. I often use 'oversized'

Peter,
Your view seems biased to me. You work in military avionics yet ou think that
airplane guys who move into electronics produce much better EFISs and autopilots
than "electronic guys" who move into airplanes. I'm not sure what you mean
by "electronic guys," but I suspect it is workers who produce commercial products.
That's like Lenin claiming that communism is better than capitalism.
I also do not have direct experience with BMA products, but I've seen their reps
at airshows. They seem to know what they're talking about just like the other
guys. If they're having problems, I am willing to bet that they are business
related decisions, i.e., shipping too early to meet deadlines, not ordering
enough parts on time, technical problems due to hurried schedules, etc. These
problems plague any organization that isn't run properly. It has nothing to
do with whether someone has military experience or not.

than "electronic guys" who move into airplanes. I'm not sure what you mean
by "electronic guys," but I suspect it is workers who produce commercial products.
That's like Lenin claiming that communism is better than capitalism.
I also do not have direct experience with BMA products, but I've seen their reps
at airshows. They seem to know what they're talking about just like the other
guys. If they're having problems, I am willing to bet that they are business
related decisions, i.e., shipping too early to meet deadlines, not ordering
enough parts on time, technical problems due to hurried schedules, etc. These
problems plague any organization that isn't run properly. It has nothing to
do with whether someone has military experience or not.

I wanted to find out if anyone has recent experience with performance

from someone who hasn't been satisfied, but most of the negative posts
I've seen, seem to be several months old. Any current info will
appreciated.

Sam, the advice on this list sometimes gets pretty ridiculous, like telling me
to buy an EFIS that I don't need. What are you, some kind of control freak?

I've been in the aircraft business as long as most people on this
list,and I've never head as many complaints about any other vender as Blue
Mountain. Why don't you just blow off the advice of this list,and go
ahead and buy there product, then tell us were wrong! :-)

Subject: | Alternator / Charging issue |
A while back my alternator decided to start cycling on and off every
now and again, mostly when under load. It will never do it during a
day flight, and only during the day when running strobes. I can
induce it at night fairly easily sometimes with the navs, fuel pump,
landing light, and panel lights (no strobes needed..they seem able to
induce the problem by themselves). I was returning from Miss. a few
nights ago and it decided to do this. I shut down the strobes and
everything was fine (as usual). I turned the strobes back on and the
last 30 min or so of the flight was uneventful.
I installed a new B&C battery yesterday and the problem occurred
again yesterday evening 1 time near the beginning of the flight, and
more so on the ground after I landed and had the engine at idle
power. I stayed in the pattern since I had a "known" electrical issue.
Here are few things I may have forgotten to mention, and I can't be
sure if this could be a cause of my problem.
2) I notice both my EI voltmeter as well as the Dynon (backup to my
gyro ;) ) are reporting about 13.5V when in flight. I would assume
this should be around 14.5 or so. I think before this problem it
did. Funny the little things you start to notice when you actually
have a problem.
3) The main problem is that if under load, the system will "shut
down" the charging system intermittently and then come back
online. Sometimes in a rapid (5 secs or so) succession or sometimes
in more erratic unpredictable intervals. Like the flight back the
other night, it acted up then stayed online for the remainder of the
flight. I'll see the voltage annunciator come on and the voltage
drop to 11.8 or 12...then it will go back up to 13.5. It may stay
for a while...the remainder of the flight...or maybe 10 secs. It's crazy.
I thought I had the alternator tested at one time and was told it was fine.
I also just replaced my main solenoid (it was going bad..wouldn't
connect when I turned the master on). That's fine now, but that
didn't help the problem either.
This problem is driving me crazy. Any and all input would be appreciated.
I'm almost convinced I'm never going to find the root if this
thing. Thanks again.

Henador,
I don't mean to be rude, but I don't think you have any idea what you
are talking about as it pertains to Blue Mountain Avionics. I have
written four posts today on this subject on two different sites. I have
been nice and danced around the issue figuring that all could read
between the lines. But for you let me be direct, if a boat anchor is
what you need then BMA is for you. If you want to fly in the clouds
then BMA is not for you....

Just to play devil's advocate, I HAVE a BMA, and have been satisfied. I think
that for the price, they offer the most capable and current functionality, but
I think you need to be choiceful with your upgrades because being first can
mean things aren't as solid as many expect. I'd rather have the option of
perfectly stable or leading tech with some possibility of issue - at my
discretion. They are certainly not for everyone.

Steve,
I saw nearly identical symptoms on my RV4. It turned out to be a poor quality
crimp on the b lead connector on the alternator.
