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.
