[Elecraft] K3 Assembly, Resistance Checks

[Walter V. Gilles]

Greetings,
 
K3/100 assembly in work.  I just did the four resistance checks that verify the power buses are not shorted to ground.  All R measurements exceeded the minimums specified.  However, that kind of leaves a big range of what constitutes "nominal" values.  Can anybody provide what are typically nominal values for these?  Below are what I measured on my particular K3 with respect to minimums required.
 
1. 12VDC IN connectors.  Required: >50K ohms   Measured: >20M ohms (out of range)
 
2. Between R36 (test point) and ground.  Required: >150 ohms   Measured: 234 ohms.
 
3. Between U12 (test point) and ground.  Required: >500 ohms   Measured: 4.8K ohms.
 
4. Between U13 (test point) and ground.  Required: >150 ohms   Measured: 423 ohms.
 
Thanks much.  Any advice appreciated.
 
Walter, N0DZJ
