[Elecraft] K2 s/n 3021 Display Board:

[Martin AC6RM]

Hello;

   I am part-way through assembling K2 s/n 3021.  The resistance checks
detailed on page 27 of the manual all checked out okay except for J1
pin 3.  This is supposed to be ground, but I get a high impedance
(>1M).

   I continued on with construction despite the failure and all tests
shown on pages 41 through 46 passed.

   Any ideas?  Seems a ground connection would be a trace issue (or maybe
a diode issue -- I double-checked the polarity on all my diodes). 
There is conductivity through the connector itself, just not to ground.
 What did I do wrong?

   Thanks ES 73,

   Martin
