    Default 14 pin receptacle 250 Syncro

    Serial # KC320772

    Connection K is supposed to be ground. It is on the other machines (KG234929 etc).

    My concern is that K has no metal pin receptacle- therefore no ground.

    Diagram (o353h_mil KC 320772 page 31) shows:

    Pins A,B.C and E grounded.

    Pin D goes somewhere- is it grounded?

    Pin K is not connected.

    My 14 pin remote will be returned this week.

    Do I ignore the missing K on this machine, plug it & go?

    Thanks, the archives have been very helpful but find anything, anywhere for this issue.

    Pins A, B, C, D & E are not grounded. Those are capacitors (C-16 thru 19) connected to them and ground.

    No, your machine doesn't use the K pin (chassis ground) nor the G pin (circuit common/neutral) that when used are typically common to each other so ignore them and when you get your remote back, plug it in and get welding.
