[Elecraft] K2 Control & Front Panel Resistence Checks...Do my numbers jive?

Evening Everyone,

I am totally done with the control panel, and right at the resistance check part of the front panel on my K2.  On some of my readings, I am not getting a reading at all.  I have a Meterman multimeter.  When the probes are crossed, 0.4 or 0.5 Ohms are considered "zero" or "ground" on my meter.  I am getting some infinite readings on my meter, even on the 2000k Ohm setting.  I just get a "1" at the beginning and nothing else...I am guessing that is infinite.  I checked the board for unsoldered components, solder bridges, and the like, and found nothing.

Here are the readings I am getting on both boards.  Could someone verify that my numbers jive with what I should be getting?

CONTROL
P2-1==>Infinite
U5-5V==>14.85k
U4-8V==>3.49k
Q1 collector==>Infinite
Q2 collector==>Infinite
U3-8==>1003k (would that be 1.003 M Ohms?????)
U6-13==>Infinite
U6-14==>Infinite
U6-29==>96.6k
U6-30==>96.7k
U8-2==>Infinite
U8-15==>Infinite
U8-16==>Infinite

FRONT PANEL
U1-1==>29.2k
U1-2==>29.2k
U1-3==>48.2k
U1-4==>Infinite
U1-5==>24.6k
U1-6 to 11==>Zero/Ground
U1-12==>9.85k
U1-13 to 40==>Infinite
J1-1 to 7==>Infinite
J1-8==>Zero/Ground
J1-9 to 14==>Infinite
J1-15==>33.7k
J1-16==>29.2k
J1-17==>29.2k
J1-18==>24.6k
J1-19==>2.67k
J1-20==>Zero/Ground

As always, thanks for the help!!

73,

David, KC9EHQ
