Circuit Board Voltage issue

[Emoreigns]

Doing the driver testing for the boards. The A socket, D socket, and 46U tested fine, but 32 had no reading whatsoever?

Trying to deduce if this is a problem on the board or elsewhere. Appreciate the help as always everyone.

What does no reading mean though? Is it 0V?

The simplest problem that will lead to super low voltage at that terminal is if you swap the R1 and the 33K resistor next to it on the B side of that board.

Yepp reading .001 V. Those two look the same as the other side of the board which is reading right?

The solder joints on those resistors haven't gotten enough heat to flow out.
