Skyview HDX Panel Installation Problems

[Joe]

If I sound frustrated, it's because I am! I have a RV-14A that I finished in almost exactly 24 months. It's ready to fly pending the Airworthiness Insopection AND getting the avionics squared away
.
I have a Dynon Skyview HDX, dual 10" screens and have been trying to get the Advanced Flight Systems Quick Panel up and running for the past 14 months and I'm still not there.

For the most part, some things work and some don't. I've tried to calibrate the fuel tank senders, but no luck there. The setup menu says I have 5 volts output which does not change regardless of how much fuel is in the tank. So … I thought maybe I had installed the senders upside down. Spent about 4 hours today removing and re-installing one of the senders. It was installed correctly and my ohm meter responded as expected. The other sensor was installed the same way so I did not remove it. Any suggestions?

I've been unable to get a position reading from my pitch and roll trims and no reading on flap position. All work as expected (motors run in correct direction) but no indication on the EFIS about their position. Sure would like to know my pitch trim position before my first flight.

Autopilot servos appear to have calibrated correctly.

Not sure about the GPS since I haven't had the plane outside long enough for it to detect the satellites.

Keep getting a "ACM Offline" caution message, but don't know what that means. Anybody know what this is?

I think my ADAHRS is working OK, but I don't trust it! I'm taking my cell phone GPS with me on the first flight as a speed backup. I know GPS speed does not translate into indicated airspeed, but it's better then nothing if the airspeed indication go South. The altimeter and outside air temp seem to be OK.

Being at a small airport (07F) we have no instrument shop. There's probably one in Shreveport, LA but I can't fly in Class B airspace to have someone look at it after I get the plane certified airworthy.

Does anyone know somebody who might be willing to travel to Gladewater, Texas to help me sort all this out? I would be more than willing to pay a daily rate plus travel expenses just to get another pair of eyes on my installation.

I have posted this same writeup in Van's AirForce, Glass Panel section so please forgive the dual posts.

Hello Joe,
For both the fuel level sensor and the trim and flap position sensors you should be able to measure the raw sensor signal when these are connected to the normal system and verify that the expected sense lines (the lines that eventually end up at the Dynon EMS) actually change levels when the fuel sensors or the trim and flap position sensors change, that would keep most of the wiring out of the loop but verify that the trim and flap position sensors are correctly powered (with 5Volt) and that the sense line is reporting a correct changing value. For the trim and flap sensors these sense circuits (potmeter with +5 and gnd supply and a sense output) should give a direct output voltage that is matching the position of the trims and flap,

For the Dynon GPS I get sufficient signal if I just open the hangar doors (standard steel hangar) in a few minutes

BTW, for under $100 you can buy a GPS receiver-repeater on eBay. Our local avionics shop has one, SteinAir has one, and I bought one recently. It's nice to sit inside and do the work which requires a GPS signal. The receive and transmit antennas have to be some distance apart. Mine has a bunch of wire - I'm guessing 30m. I have yet to permanently install mine, but initially got it working by simply putting the GPS antenna on a stand and sitting it out in front of my hangar in the clear.
