Ive taken F7000 off the board to see if PPBUS_G3H fluctuates on the pin one side of the fuse when its not continuing on to the system. Its still fluctuating but not as much (or my meter can't see it) it looks like its going from 7v to 12.95v repeatedly
I started testing all caps and resistors on the PBUS side between U7000 and F7000, found R7062 (which should be a 1ohm 0201 resistor reading as 147ohms so U7000 probably thought there was a ton of drain with that at 147ohm.
Swapped R7062 out and now I have a solid 12.95v on PPBUS_G3H up to F7000
