L8 + 4.99V | L10 + 4.99V | L11 + 0.02V | L9 + 0.02V | L15 + 4.89V | L14 + 4.70V
Of these, both L11 and L9 are connected directly to ground (black wire).
I also measured the voltage of three other inductors L12 L13 L16, the voltages present are these:
L12 + 4.65V | L13 + 4.65V | L16 + 4.99V
Ok, nothing 3.3V then. Where were the other inductors you measured a few days ago (L1 0V | L2 0V | L3 + 4.98V | L4 + 2.50V | L5 + 3.47V | L6 + 4.93V | L7 + 1.77V)?
Looking at the voltages of the PCI PIN by PIN, I have voltages of 3.44V on PIN A6 A7 B7 B8, of 3.30V on PIN A15, of 3.47V on PIN A17 B44, of 3.52V on PIN A34, while in PIN where there should be the + 3.3V I have not found any voltage.
Don't know if those are as expected. Pretty sure A6,A7,B7 and B8 are ok.
Think I'm out of ideas at this point, other than the boring and time consuming task of putting the meter in resistance mode (20k range probably) sticking one probe on a PCI 3.3V pin and then carefully and methodically testing pins on other devices to find what, if anything, they connect to.
