Met my goal for another week! Even better, today I finished all the initial testing of the wires to and devices on the instrument panel. I sent an email to Garmin G3Xperts asking for help on three things; GAD27/GEA24 configuration issues, GAD29 not recognized and a transponder fault message. Updated software on the GNX 375 and installed the database. Updated software on the G5 and on the GDU460. The GDU handles updating all the other G3X system devices. Continued testing and troubleshooting the issues after I sent the email and thought of more things to try. Updated the spreadsheet and schematic to show the power to the P Mag circuit breakers coming from the main bus instead of from a fuse. Updated the wire list spreadsheet with information on all the connections I tested.
