Raymo - I know you meant the Mic jacks at least should have the shoulders & flat washers installed, the headset jacks are not so critical - just for the benefit of the OP ;)

Agreed re paper copy over digital however colour versus black & white ? That’s a question for social media, not for a forum where people may need real help sorting out real issues.:)

You’re not serious 😟

If the noise is still there with the Dynon on & out of the panel its something else & not the wiring causing the problem IMO. FOD in the fan area ?

Ok guys, just some relevant some info here. Many people have all sorts of combinations of equipment so it may be a good idea to be specific eg - transponder model, is it the SV- 261/262 version or the Trig TT 21/22/31 etc? GPS input direct to Transponder = if using the SV- 261/262 then you MUST...

A suggestion - why not just connect a shunt in the Alt output line ? as I mentioned earlier. That way you always see the essential basics of the volts/amps (as the volt sense from the bus is connected to EMS anyway as per EMS wiring) & if you want to explore more, just select the VPX page.

Andy, there is one other simple thing to do before you contact Dynon support - bypass the panel power switch for the Dynon by just removing the wires & joining them together as there is absolutely no need to have a separate switch, it potentially just creates another failure point. Then do the...

Alan, FWIW I use an amp shunt in the Alt B lead to show the output amps &, like DBRV10 says, just access the VPX menu to determine where an issue may be if I see any changes from the normal expected. As you know the VPX will show Alt output, amps IN to battery & bus amps current use all at the...

An input from me that may help (experience with around about 65 + Dynon installs) -- 1. Absolutely correct. 2. Maybe happens but not likely due to wire colours - most people understand that red goes to red & yellow to yellow etc. 3. an important difference here - IMO it's not the 25 pin...

Thomas - that’s a pity, I’d rather see you speed money on avgas that buying something else you don’t need, the 430w & Trig combo will do the job of ADSB OUT. There will be something missing in the troubleshooting here - I’m willing to assist offline here if you want? will PM you.

Good to hear its sorted ;)

My bad re the resistor (its not required), confused it with the requirements for SV system. "Could there be a programable change in the D180 that would affect my ADSB. The warning I am getting on my Trig transponder control head says "WARNING NO GPS POSITION." Just want to be clear here -...

Ist, & easiest thing to do in these cases is to thoroughly check the servo shear screw.

ADSB OUT issues - in a word, no. The legacy Dynon units have no impact on the ADSB problem. I’d check the RS232 out from the 430 for continuity, also it should be a separate input to the Txpdr set as Garmin ADSB +. Also check that the 1.21k resistor in that line is not broken.

brennon - if your aircraft was a certified one then, yes, you most likely would have type specific settings however EAB aircraft can be wildly different in how they are built ( don’t ask how I know🙄) with issues like control friction & improper rigging In play here. Regardless of what you are...

Tommy, I need a clearer picture so will PM you.

Russell - whether the Op's issue was resolved or not will not resolve your situation, the best people to talk to is Dynon Support in this case. You have done everything reasonably to find the cause of the problem.

Crimped, correct ? did you give a gentle pull on the wires to confirm the pins are locked in place ? The wiring - premade or self made ? Separate power, 20 awg wire to the servos & not just connected using a Dynon SPL (splitter) harness ? Have to ask as we can't see the wiring & need to get...

No need to remove the unit ,yet. If you turn the master on & let the Dynon boot up, & then master off, does a 30 second countdown type message display on the Dynon ? If YES then you do have an internal battery. The other question still needs to be answered - how many volts is displayed on...

What type/brand of connectors are they ?
