ok,
R103 is not marked on the board at all. it's not in the Doc except for on the schematic and in the parts list. but is not in any of the photo's of the board in the manual. why? because it sits right against the center bulkhead underneath V101 so it can not be seen in any photo's.
R103 is reading 5Mohm instead of 3K. it is a 5W power resistor.
Looks like Digikey may have a suitable replacement so I will order it and wait until it arrives to do any more troubleshooting
if I'm lucky this is all that is wrong.
I had to trace out the circuit board to find it.
checking from R101 to Pin 8 of V101 was ok.
then checked from R101 to cathode of D101 and continuity showed a open.
flipped over board and visually traced it and that is when I found the pins for R103. flipping it back over showed it under the V101 tube. I would have thought Keithley would have called that out in the manual.
Will update after I've got R103 back in place.
Oh and yes, my info was bad, it is 112 V on pin 8 not -112
