Doing that is the same as connecting the two alternators in parallel. The Dynon would read the higher of the two voltages, not the sum. Using a relay will work.

From: "Eric M. Jones" Just my two cents worth but it is important to understand that many regulated power supplies and regulator ICs require a minimum load (current draw) before they will regulate. It is possible that the intercom does not draw enough current to do the job and a load ohm resistor across the input power but after the on/off switch might be required. This load resistor is an important circuit element even with LM317 regulators. They specify a Min Load Current of a few milliamps, but other supplies can be several tens of milliamps or more. -------- Eric M.

The Van's supplied cable is not shielded. Instead, individual wires are twisted together. Since shielding is optional, I would not be too concerned about making a splice at the wing root. This application is not critical like a coax carrying a radio frequency. Any type of connector should work, like a D-Sub or even a 4 pin automotive trailer hitch connector. Since Dynon uses a D-Sub on each end, that would be good choice for the splice.

I expect the cockpit noise will be "fairly high", and it is my understanding that if each person pushed a button everytime they wanted to say something, it would be much less annoying. Or is it not worth it to hook up the PTT design, and simply adjust the squelch to handle a loud cockpit. Mike Welch _____ From: stein@steinair.com Subject: RE: AeroElectric-List: Icom A210/A200 owners Hi Mike, FWIW, I'd encourage you to just put in the external intercom and be done with it. The internal intercom of the 200's is barely what anyone would call a functioning and usable intercom. I won't bore you with the details, but suffice to say our experience has been that almost any intercom is many times superior to the internal one for many reasons. BTW, the 200 is indeed a great little radio, just not a very good intercom! My 2 cents as usual..

I have a SoftComm International ATC-2 potable intercom that I got for my plane years ago. I also have a Icom A200 (mobile style). Basically, it the same a the regular A200, it's just that it comes more like a CB radio; attched mic via a coiled cord, speaker that pluds into a 3mm plug recepticle, hot/grnd leads for power. Anyway, back to my question; For those guys that have experience with the built-in intercom function of the Icom radios, would you say that that alone is sufficient (for a 2-place), or is the intercom part "lacking", and in need of a separate dedicated intercom? Frankly, if the concensus is that the Icom is up to the task, I'd rather just go ahead and install a couple of jacks and be done with it. (the intercom part, I mean) So, wuddaya think of the Icom intercom??

The most important thing to remember is to only change one variable at a time. If you have swapped headsets and the noise remained, we can rule out bad headsets. I would suggest the following decision tree. 1) Test the intercom in another aircraft if possible. If the problem follows the intercom, the intercom is bad. 2) Test with the engine and ALL other electrical devices OFF except the intercom. If no noise proceed to 3 3) Repeat 2 with engine running and ALT off. 4) Repeat 2 with engine and ALT on. 5) With engine off, turn on separately each other piece of electronics. 6) Repeat 5 with engine and ALT on.

I've changed the supporting structure for my instrument panel and subpanel for my Sonex and would like to get some feedback on my ideas for securing the wiring. The main panel is tilted per plans at 30 degrees and is attached via piano on top to the glareshield with a piano hinge, on the sides with nutplates, and to the subpanel with another piano hinge. The subpanel is from a 1/8" thick extruded angle, which is 1.5" tall and 5/8" deep. Pic 004 is the only one taken with the panel in the closed position. The others are with it tilted partially open for viewing. One concern is getting the wires going to the back of the MGL Enigma EFIS so they aren't dangling down onto the control cables. Looking at pic 006 you can see two white wires going into the left side of the EFIS. I'll move these (as well as a blue wire not shown) into the spiral wrap so they will exit the bundle to the left of the EFIS, about where the grey cable exits. This leaves only the wires going into the 9 pin connector. It came delivered with these wires looped around through the ferrite tube as shown. Orange and green for OAT will go to the red and green wires coming out of the wrap on the right. White won't be connected to anything. This leaves the black ground and red supply wires. I didn't make the black ground long enough, so I'll resplice it. This will allow enough slack to move the ferrite tube to a better place instead of dangling close to the control cables, and more importantly, the center flap and brake handles. So I'm wondering where a good place for this ferrite tube would be. If it needs to be secured, I could strap it on top of the 9 pin connector with a couple tie wraps around the outside of the tube. Or turn the tube 90 and run it through the middle. -------- Dan Read this topic online here: http://forums.matronics.com/viewtopic.php?p=311255#311255 Attachments: http://forums.matronics.com//files/panel_wire_bundle_006_140.jpg http://forums.matronics.com//files/panel_wire_bundle_004_128.jpg ________________________________ Message 19 ____________________________________ Time: 10:23:29 AM PST US Subject: AeroElectric-List: Re: Spiral Wrapped Panel Wire Bundle From: "messydeer" Another issue is securing the spiral wrapped bundle to the subpanel. I had thought of simply drilling holes every 6" through the top of the subpanel and cinching the bundle down with tie wraps. You can see a couple of temporary safety wire pieces twisted in place in the pics. But instead of doing this, I thought it would be better to support the bundle with those saddle anchors that can be riveted on. The final issue I have is where the spiral wrap drops below the top of the subpanel on the cabin's left side (right side in pics) and goes between a switch cover and the vertical face of the subpanel. I can't have it continue on top because the light with a red and black wire would interfere with it. I figure I could wrap this area with silicon tape to protect it against the edge of the subpanel. Or maybe adding another section of spiral wrap over the existing spiral wrap, making two layers of it. -------- Dan Read this topic online here: http://forums.matronics.com/viewtopic.php?p=311257#311257 Attachments: http://forums.matronics.com//files/panel_wire_bundle_007_195.jpg http://forums.matronics.com//files/panel_wire_bundle_008_298.jpg ________________________________ Message 20 ____________________________________ Time: 10:38:05 AM PST US From: Mike Welch Subject: RE: AeroElectric-List: Icom A210/A200 owners Hi Stein=2C I'm building a Kolb MkIII.

Because of my exhaust system=2C I expect my engine/prop will be more quieter than most of the other MkIII's=2C but that's only conjecture=2C at this point.

I threw away the bracket=2C and mounted the tray into my panel=2C just li ke any other Icom A200 built-in. (Now=2C nobody will know my secret) Compound the Icom A200M with the fact I have a portable Softcomm Int'l AT C-2 intercom. There aren't any small colored wires=2C exactly=2C just two cords....one th at is a pilot/co-pilot microphone combo plug=2C and a single headphone plug. (the colored wires are inside of the large black cords) These two plugs would plug into a typical mic/headphone system. Somehow =2C a guy would need to incorporate a PTT switch=2C but I haven't figured that part out=2C yet. The Softcomm intercom has two large wires(looks like AC cord a toaster wo uld use)=3B the first one (microphone) has 4 wires inside of it=3B 1) white....which goes to the mic#1 tip 2) blue......which goes to the mic#2 tip 3) red.......which goes to the center section of both mic #1 & mic# 2 4) black....which goes to the base of both plugs The other large plug wire (for headphones) has two wires inside of it. A red one and a white one. I haven't identified which one goes where=2C but it's easy since I can get to the circuit board and chase them with a multimeter out to the plug. From what I can tell=2C it doesn't look too tough to draw up a wiring sch ematic and get it done. Thanks for everyone's help. I attached a picture of my project.

I have 28V SD20 and LS-1A as Alt#2. For the sake of discussion, assume the alternator is turning 3500 rpm and generating 20amps of current (per spec). How much of this current/power would typically be re-consumed to drive the regulator/alternator field at max 20 amp load (i.e. what is the available "net" power)? I know the std/recommended LS-1A setup has a 2A breaker on the sensing lead and a 5A breaker on the field lead, but I'm guessing it actually consumes less than 7 amps of it's 20 amp output (or is that already 'netted out' of the 20 amp spec).
