These were taken without the XR header plugged in, sorry I should have mentioned that. Q103 measured 33v/85v/47v (pins 1, 2, 3, which I think is B, C, E). When I tested the Voltage regulators VR100/VR101, I noticed the ground pins all have approx -1.3v on them, in fact -1.3 is volts seems to appear on the grounds on many parts on the board.
