I usually have the same issue while flying in the vicinity of radio towers. At first, I was a little bit scared because of the noises, but then I understood that it gives some kind of adrenaline. Read this topic online here: http://forums.matronics.com/viewtopic.php?p=502331#502331 ________________________________ Message 2 _____________________________________ Time: 08:04:24 AM PST US From: David Carter Subject: AeroElectric-List: Locking 3P switch? Please see attached diagram. I'm looking for a better solution than what I'm showing now for the "test/kill" connection on the SDS CPI-2 ECU. I believe it would be better if this was on the same switch as the power to the ECU & coil, so that the "test/kill" connection would be grounded any time the ECU & coil power supplies are switched off. Grounding this connection causes the ECU to stop firing the coils/plugs. When power is removed from the ECU & coil primary supply connections, the ECU remains on & automatically switches to the backup power supply. The manufacturer's intent is that this is supplied by a dedicated battery with an unswitched supply rather than the Z101 engine bus, but that's not relevant to the question at hand. Can anyone suggest a locking 3 pole switch similar to the Honeywell NT series, or another creative way to achieve this with more common switches?

The company used to offer a small, round pin connector for that purpose, but not any more. Would like to be able to disconnect the actuator rather than cut solder joints, if possible. Any suggestions for a connector for fine wires like that appreciated.

Here's a suggested method that is much easier to fabricate and decidedly more robust as a finished installation: https://tinyurl.com/cmq7epd Bob . . . Un impeachable logic: George Carlin asked, "If black boxes survive crashes, why don't they make the whole airplane out of that stuff?" ________________________________ Message 6 _____________________________________ Time: 03:37:37 PM PST US From: Charlie England Subject: Re: AeroElectric-List: MAC/Ray Allen trim actuator connections Machined subD pins should work fine; if needed strip twice as much and double the wire before inserting in the pin. If you want them 'orderly', use a 9 pin housing; otherwise just use heat shrink over each mated pair.

I'm having an issue with the received volume on the initial response to my transmission in that the volume is about 1/2 of normal, and it only is in the left headset speaker. Either this has recently started or I haven't noticed it before. The radio is stand alone, no audio panel is installed. Garmin says take it to a dealer but there aren't any conveniently located. Any ideas?

He simply used good quality pins and sockets and then mated them and individually heat shrunk them as you describe. I think he may hav e put a larger heat shrink sleeve over the entire bundle for an extra payer o f protection and neatness. It looked like a neat and tidy solution. Certai nly not as quick to disconnect as an actual connector, but then how often do you remove the elevator or tail of your airplane? I am considering this approach, but may also just use a 0.062 pitch mini mol ex as they are fairly robust and small, but not weatherproof. A 5 pin Weath erpack or Metripack is weatherproof, but much bulkier.

Stagger the joints and heat-shrink each one, then heat-shrink all five. They don't need to be in a housing. It makes a fairly small and manageable bulge. I think Bob has a write-up on this technique. --Dave On Fri, Jun 11, 2021 at 3:25 PM Tom Barter wrote: > Greetings, > > > I=99m in the process of installing an MAC/Ray Allen trim actuator, and am > wondering what the best way is to connect the five 26 gauge leads coming > out of the actuator to the corresponding 26 gauge five wire control cable > that will be routed up to the cockpit.
