Board was previously ultrasonic'ed, but half of the J9500 collar was lifted up, so I assume there may have been some corrosion there, I re-soldered the the four ground points (pins 51,31,15,49) so the J9500 seems whole again, no other pins look corroded or damage inside or out.
Unfortunately PP3V42_G3H at pin 21 is still 0V
Is it safe to assume something is shorting inside the J9500 or is there anything else I should look at?

Ah I see, I think, R5380 is also 0V with known charged battery, does this mean a short to ground somewhere in 3V42?

Check the bridge cable for corrosion as well. I often see corrosion on that pin shorting the line out. Try a new cable.
