1.24 at terminal mate point to the motherboard, while active/on and plugged in.
3.7v at each of the l2/r2 triggers
and last but not least, i snipped each of the wires from the analogs (psp1000 per spec) and no voltage variables changed. pic of motherboard attached so you can see how things are run under the CM
See the attached photo and see if you get 5V without the Pi attached and the power switch held in the "ON" position. I wondering if you have a cold solder joint on the 5V pin of the L2/R2 pin. It is possible to measure a connection but if its a weak one then once you start pulling some current the voltages are way off due to a high resistance path. If there was a solid connection and you measured 1.7 volts there the pi would not run. Let me know your findings.
