820-00426 short on PPBUS_G3H

[Sr. Robot]

Hi, i have a 820-00426 with a 0.6 ohms short on PPBUS_G3H.

All area around L7130 on both sides of the board was getting very warm, particularly L7130. Removed L7130 and the short was on PPVBAT_G3H_CHGR_REG side. Then removed both F7140/F7141 and the short is on the PPBUS_G3H side.

Im injecting voltage on PPBUS_G3H, however nothing seems to be getting not even ward. Im as high as 19v and 6amps

You are probably not injected at all.
Puting 19V there, your board may be trash now.
Even your lab PSU went in protection mode, 19V pulse there is high too much.
Did you compare short value with the readings on all coils?
