    Default G3X power up- PFD1 not connected

    Just powered up my G3X and it gives me message saying PFD1 not connected. I enter into config mode and try to load data files but can’t get past this message. Any ideas?

    I think this indicates that the display thinks it is PFD2 or MFD1 or MFD2. Whatever it thinks it is, it doesn't think it is PFD1.

    To configure a GDU 465 as PFD1 program pin 1 needs to be grounded and program pin 2 needs to be open. If the ground on program pin 1 has failed then the display will think it is MFD1.

    I'd suggest checking that P4602 pin 10 is connected to ground. In the CubCrafters schematic this ground is provided by a link between pins 10 and 27.

    ( I have never seen this issue and the suggestion is based on my, perhaps incorrect, interpretation of installation manual section 26.4.6 Mode Selections, GDU System ID Program Pins)

    Ok. They wired the harness wrong. Pin 9 was to pin 27. Changed the pins to 10 jumped to 27 and that fixed.
