Avionics

Discrete #3 for Canopy Warning, LH Joystick fix (3 hrs)

Received extractor tool from Stein Air so I could switch wires in connector J244 on GEA24.  Switched wires at Pin 41 and Pin 42, so Purple/Blu wire now at #42 = Discrete #3.  (and Purple/Grn is now at Pin 41, for Discrete #2).  Needed to align Discrete #3 with code within Canopy Warning program from Vans  (recently uploaded into G3X).   Also checked all 9 pins in LH Joystick connector:  confirmed need to switch wires in Pin 1 (black) and Pin 2 (orange) for correct Trim Up vs Trim Down to be same as RH Joystick.   Kevin (owner of Tosten grips) has been helpful, and is sending new Molex pins to crimp on when I switch wires.   Confirmed AP/CWS switch failure to work is not in joystick, but LH Common Fuse Harness.  Josh at Stein Air helped explore fix.  Seems best option is to install jumper from LH 50 pin connector Pin #3 to RH 50 Pin Connector Pin #18.   OR...run wire from Pin 9 in Common Fuse Harness at LH Joystick to RH Joystick Pin #9 wire (ie joystick to joystick).  Learned this wire sends signal to AP servos...not IP...so not connected to anything at panel.   tbd....!
J244 connector at GEA24 partially dis-assembled, but prior
 to swap Purple/Blu with Purple/Grn. 
 This aligned Discrete #3 w/ Canopy Warning program.
Success!  Canopy Warning appears as "Check Canopy".  Flashes
 for about 5 seconds, then steady on.  Above 1700 RPM, should
also hear audio warning.   (Other warnings due to engine
 not running, etc.) [sorry- hard to get focused pics of display]
