820-3332-A Macbook Pro Retina 15" Shorted on PPBUS_G3H

We may not have the same working hours; this is not online assistance.
I try to help you, but I expect that you don't experiment the way you did.
You can get more damage on the board.
Q7080 seems to be shorted, change it now.
035 diode mode on the system side of the fuses is the problem.
That means 60-70 ohms (into ohm scale).
Now check every big coil in respect to ground.
Let see if you get the same value.
If yes, check the corresponding MOSFET to PPBUS_G3H (for that coil).
BTW, you don't need to check values on both fuses; are tied together, cannot give different values...
After replacing Q7080 check if get correct voltage on L7030; fuses removed, of course.
