Baffled
Lucas, thanks for responding. Been trying to get a hold of you all day. Here's what I've done:
Verified all wiring a dozen times (honestly). I have verified that I only have ARINC A & B in going to both the Autopilot and 540 (they are Tee'd together since I took the switch out on this panel upgrade. Yes, I used to have the switch to select EFIS or GNS 430, but Rob says that wasn't needed anymore so I took it out and tied them together) One lead is not connected.
I verified with the 540 out that no other connections are to the ARINC lines on the Sorcerer. Here is how they are connected:
Sorcerer 540
26 48
27 49
540 ARINC out is on pins 46 & 47 to the ARINC module.
RS232 to the Sorcere is on pins 25 and 3 (I know you told me 7, but it wasn't talking to the EFIS on 7 and I verified with an LED signal tester that the OUT was on 3, and it is now talking to the EFIS)
Here's what happens:
The autopilot will track off course on what appears to be a converging course to the target in all of these modes: 540 GPS direct to, EFIS Internal Flight plan Direct to, and ILS NAV it will also track a converging course to the MAP. The EFIS screen in ALL cases shows that it is sending a correction to the autopilot but the autopilot is not correcting.
In HEADING mode it flies about 3 degrees OFF. If I use the EFIS control panel to fly LEVEL, it turns to the right.
I tried the autopilot in a mode by itself just engaging it so it showed bank angle and it wanted to turn even though it said 0.
I am open to anything, but I don't see how this could be wiring at this point. And I've gone over the wiring every which way to Sunday to verify it is according to the diagrams.
Let me know what else you need. I would love to be able to see the information going TO the Sorcerer but haven't figured out how to do that.
Thanks.
Vic
