Always connect to the EIS/EMS grounds - you can pair up the grounds if there are not enough individual grounds available - that absolutely minimises the probability of ‘issues’.😉

Most likely not a wiring problem - if the network wires were incorrectly installed then you would get a message telling either 1 & 6 or 4 & 8 needs sorting & power/ground are good because it will power up & ‘lock on’ as you indicated. Are you able to swap servos (assuming you have roll & pitch) ?

Double check the location of the probe it may be in the fuel in the fuel bowl ? Don‘t ask how i know this 🙄. Suggest you remove the probe & if fuel runs out you have it mounted too low .

Maybe the shear screw is broken?

Have you checked the ADAHRS mount security ? ;)

I’ve seen the exactly the same issue years ago,cleaned the pin contacts with a soft wire brush then flushed the gunk out with contact cleaner - the EMS still works. The tip up canopies can be notorious for this IF you don’t ‘shield’ the avionics from water ingress - I’ve used heavy aluminium...

Understand it’s real hard sometimes troubleshooting online considering “We” are unable to see/know how your plane is wired. If I was a betting man I’d say the ‘fault’ is not with the VPX itself - from my experience they don’t fail unless it’s an installer induced problem. I’d recheck the serial...

Airguy pinNed it down. PH-LRV - thanks for posting the solution, it should/can help others.😉

Just in case anyone was wondering if Raybo is a scammer I can assure you he is legit - has been a good friend of mine for 30+ years. He will be in USA & can make arrangements for delivery.

Stevec, MY BAD, very sorry - know you guys 'over the pond' are normally good guys At post #7 ....see if the 'issue' is still there -IF yes, then "bite the bullet" & install a B&C Alternator - what I (now obviously) meant was to say IF no, then bite the bullet....... ;)

Bingo, I see where I went off script.🥴

All I indicated was to disconnect (the field wire plug) the alternator. Run engine. Nothing about ”Problem remains”, however if it does remain, after the above, then the “issue” obviously must be elsewhere 🙄. Never thought I’d say this, &mean no ill will, but ‘Stop acting like a troll’ you can...

"Well I have what’s called a formal education AND experience, not only in electrical engineering, but in pressure transducers" Sometimes I'm wrong, hopefully not too often, & other times I'm good - hopefully between us WE can help others find a solution to their issues. I certainly don't have...

Guys the reason WHY I made the suggestion is exactly what GKC said. I did not want to give reasons when a simple unplug of the alternator would/could give the outcome I expected. Sometimes a simple action can give instant results - it’s called experience 😉

Mark, Your link to the Zenith page is compromised. Which Dynon system do you have ? & which engine ? Interesting to note the 13.8 psi & 138 psi -there's only a decimal point difference - strange. Not all sensors go to zero when engine is shutdown - that is explained in the Dynon documentation...
