K3 Problem in Assembly, need advice

[Brian F. Wruble-2]

I am assembling K3 s/n 7394.  I have come to the step on page 45, DMM
resistance measurements.  The resistance between a terminal on U12 and
ground measures 445 ohms.  It is supposed to be >500 ohms.  I am using an
accurate Fluke DMM.

What am I looking for?

Hi Brian,

this measure point is the output terminal of a 5V voltage regulator (U12
MC7805ACT).
A value of 445 ohms is not alarming. A matter of tolerances in all parts
connected to this point.
But I expect Elecraft will react too.
