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...

Ok, what I'd do is unplug the Alternator & ground run the engine to see if the 'issue' is still there -IF yes, then "bite the bullet" & install a B&C Alternator & regulator. ;)

Do you have a plane power alternator fitted ?

Your unit is probably the later unit so modifying/replacing it will not change anything if it's an earlier unit in which case a cheaper alternative may be to use the L-C0M brand of 'filtered' dsub connectors. I believe they were used as a temporary measure to mitigate the problem until a...

I’d be checking the connectors especially if they’re the type where the shield is held in place with a nut. Also check the centre pin is locked in place as the tip of the pin should be close to being flush with the end of the ‘body’ - that applies to the shield crimp sleeve type as well.

What I do is just select any 5amp circuit & then label it as Garmin 175 & allocate it to an avionics switch (you can have many other avionics allocated to it too) & you’re good to go.😉
