You don't say what model Trig VHF you have, But I will assume a TY91 or a TY96 On a TY91, connect your alert audio HI to pin 20 of the main unit connector. If it is a TY96, then connect to Pin 14

Your voltage sense and your amps are two different sources giving you the same information. It really looks like your charging system is not working.

You are probably right, but it's a nice quick check to eliminate one possibility. Take literally two minutes. That is all we are suggesting. Both Jake and I do this for a living, we have seen a lot of weird faults, and it's best to start with the easy stuff first.

I have had a Plane Power alternator cause all sorts of dramas due to stator wiring connections cracking off internally. (it is a big problem with PP alternators) It still worked, but obviously the output voltage was something other than clean DC. Also the amps were jumping around, but so fast...

Yes, I've seen an installation where on transmit, all the CHT and EGT's go high. In this case, it was because the VHF antenna coax (even though it was RG400) was run very close to the EMS and EMS wiring harness. Moving the coax away fixed it. I don't think the EMS is shielded very well from RF...

On your hollow robotic receive audio, are you using a stereo or mono headset? Sometimes a mono headset in stereo jacks will cause some weirdness.

Just to check, have you adjusted the sidetone on the X25 COM? It might be set at zero. Sidetone is a product of the radio during transmit

Ah, ok so it is trying. I am guessing that if you roll the aircraft without the AP (a normal turn), it takes some rudder to prevent the slip. I have no experience flying the S7 or any floatplane, however I expect the floats have a fair bit of say in wanting to go straight, and a banked turn will...

I would be checking the shear pin in the roll servo. It will still have enough friction to feel ok on the ground, but won't have enough to drive the ailerons in flight. Worth a try...

When you talk to you passenger on the intercom, do you have sidetone? Do you only not have sidetone on transmit?

@jakej will be the man

During the two yearly check, the altitude of the EFIS is compared to the altitude on the pitot static test set. If it is incorrect, the ALTADJ in the EFIS setup menu is used to make them read the same. This also adjusts the gray code output to suit.

Sorry for the mix up with the manuals, I should have more thoroughly read your first post. Do you have a transponder in your plane that has the encoder connected to it? Encoders are calibrated to pressure altitude (referenced to 29.92 InHg or 1013.25Mb), not barometric altitude. Depending on...

Yes, this is on page 7-1 of the installation guide. I urge you to read the manual

I think I have two here somewhere in the hangar that have been removed during HDX upgrades. Where are you located?
