Hi guys, I have this board and when checking the fuses I have been able to observe that F8400 is correct but I have a short to ground in PPBUS_G3H

I need help finding the component

thanks

Did you disconnect the battery when checked?
What is the exact ohm value of the short?
Compare with the value on each big coil.

All good, even L9060?
If yes, then is safe to use voltage injection method.
