I gave you a place to look and you seem to have completely ignored it. When you put in the new ADAHRS did you do a network detect to find it and see if it was responding at all?

Well it’s not when it comes to the autopilot servos. The manual and plans is pretty clear about it. Do you have 12 volts plugged into the network cables anywhere, more specifically from the autopilot servos.

If there are no network errors it can really only be the ADAHRS or the display (less likely) How do you have your autopilot servos wired up? Power for those doesn’t tie into the network cables right?

What exactly is making it unusable?

Depending on what type of trim you are driving the power supplied might not be enough and perhaps neither will the additional amp power. I have documented a working circuit and solution on here somewhere to overcome the problem if you end up having it.

after many more flights the answer to this ended up being a combination of not capturing the glideslope at 200kts and some autopilot tuning.

It’s green. I don’t have a photo.

You’re correct about that. I’m arming it after the glide slope comes up. The display also shows that it’s armed. End ready to capture.

It's the IFD 440. The 440 is set to VLOC. I manually made the switch vs allowing it to auto switch

Coming in from underneath I’m in alt hold mode with vnav armed Glide slope comes in and captures Airplane flys straight through glideslope. Works fine on RNAV approaches. Airplane is a Glasair 3 and the default settings have been fine for me with minimal complaints other than this. I’m...

Yes. I’m seeing this too. There are actually 2 airport diagrams in this current set of charts. One is not geo referenced (probably the one you opened) and the other is and works normally. Very annoying for sure. I was curious if it was just me but I guess not.

I don’t think the Ethernet plays in here. Make sure the serial from the ADSB rx is wired to both panels correctly. check settings, should work.

I also have a Glasair, and probably the same actuator. The trim amp isn’t going to do it. I made a post a few months back with a drawing you will need to build. Mines been working flawlessly.

I would, did, solder it together. If r do the dsub plan as posted above.

Sounds like that ADAHRS also isn’t mounted flat.

That procedure is likely a bug, not a feature

I built this as drawn above and it works perfectly with no temp or current issues. I just wired it straight into the pololu board, used heat shrink on everything, the wrapped it in electrical tape and zip tied it to the wiring. (It was small enough). No problem.

Ok I’m stumped. New install on a Glasair 3, trim via a Linear Actuator rated at 3 amps (so no trim amp) Nothing out of control panel. I disconnect the motor and put a meter on it while commanding the motor via the panel, no voltage observed at the motor. Pull the pins from the connector and...

remember all those devices share power and gnd from the display. It sounds like a bad ref voltage to a bunch of stuff which suggests to be it’s getting pulled low somewhere. I’d try replacing some network cables. Are they all single cables or do you have some splitter cables?

I’m probably going to make my own breakout board and set it up for a 9pin.
