[Elecraft] KPA100 voltage checks not right

[Roland & Elvie Whitsitt]

I'm putting together the 100 watt option.
Some of my voltage checks did not come out right. 
U1 pin 15 was suppose to be 0 but shows 5.6
U1 pin 20 was suppose to be 5v but shows 0
U1 pin 27 was suppose to be 5.8 but shows 0
U1 pin 28 suppose to be 5.7 but shows 0
U2 pin 10 suppose to be 12 to 15 but shows 10.72 (the voltage has always displayed about 1/2 volt shy on this k2)
U4 pin 1 suppose to be 12 to 15 but shows 11.72
U6 pin 6 suppose to be 0 to 0.5 but shows 4.97
the rest of the pins are close to specs.
Oh what shall I do?
