I’d check it out by a process of elimination, unplug 1 x SV device at a time to find out which cable network is at fault & then do a continuity check of pins 1 & 6 (Green& Blue wires) & also check that those pins are locked in place by giving a gentle pull on them :)

OP - "Make sure a pin is not pushed back on the connectors". A continuity check will not show what Garrett said, you need to gently pull on the wires to see if the pins/sockets are locked in place.

There lies the problem - I would never use RG58, modern avionics require a much better coax like RG400. RG58 is not allowed to be used in new installations in certified aircraft either so I would not use it in 'experimental' aircraft for the same reasons as the certified market ;).

Do you have RG58 or RG400 coax ?

Basically yes, your avionics installer should know what to do.

Alan, just a thought - if you haven’t done this try using the iPad without ships power & pull the adapter plug out of the 12volt socket if that’s the way it’s been powered. ;)

Network is the 9pin dsub wiring, the other one is Ethernet which is only between both screens ;)

As the Transponder was still showing it looks like you possibly lost the network connection to the left screen ? Did you check that ?

The ‘tip’ re p-static was more an FYI as well. I’m figuring, from the unchanged symptoms, that you transmitter had had an issue similar to what happens when transmitting without the antenna connected.

Nothing to do with radio getting wet ! Ever heard of p-static ?  Look it up  ;) I had the same issue once while flying IFR in my Glasair, lost comms with ATC - I could hear them sometimes but they could not hear me.  Never had that problem since. Without being able to look over your installation...

Is the aircraft a composite airframe ?

As Ray says, check your grounds for the EMS thoroughly. Are you using a forest of tabs ? & , if yes, the push on terminals from the same source ? Other cheap low quality terminals can cause grief. I always make sure that I use the grounds out of the ems ( sometimes splitting them if...

Where is the ems mounted ? Is it an RV with tip up canopy ?

Hongie Are you in Oz ? if so then PM me.

FWIW I use the SV42T on the Glasair, just need to carefully align it so the pushrod travel is parallel to the for/aft travel of the elevator bell crank. Having the auto trim option is the best way to go with the Glasair due to the ‘heavy’ trim spring bias ( no trim tab).

Morgan, What I do with some aircraft is disconnect the static line, just vent it to cabin & then do a test flight - it’s a simple check to eliminate static system issues. Is it possible for you to email me a picture of your servo & mount method ? I’ll pm you. Jake Glasair IIS FT. 2400hrs Australia

resistor is generally used as a 'fuse' for voltage output ignitions & magnetos & also has a dampening effect with ripple current.

IF your connections are good the I'd add a 30KoHm resistor in the rpm line to the Dynon (if you don't have 1 already) worth a try & it's very a cheap 'test'.

I know this is after the horse has bolted however I never have the EGT probes that close to the cylinder (unless there is absolutely no choice due to slip joints or weldments) as it does reduce the life of them. FWIW  My preference is around 3" from the cylinder. ;)
