I have no direct experience with the K1, but the first think I would look for is the diodes installed backward.  The band will be on the output (negative) end of the diode.  The next thing to look for is that all the diodes are open.

I am a first time "K1" builder and am having a very difficult  time getting the proper voltage measurements for the test on page 46 of the manual.  
Test point J7 pin 8 should be 3.8vdc  I get "0"
The test points on Diodes "D9","D10","D11","D13", all measure "0"
Any suggestions as to how to go about troubleshooting these problems?  I have had no problems up to this point, but this has me stumped.
