this board had a short on ppbus and c6405 was removed to fix that. now i get 20v 0.000a 3v3_g3h is 3v. pp1v8_slps2r is 0v and doens't have a short. is this a issue with the coils surrounding u7800? If so i'll need to remove that cover that surrounds u3900/u7800

"3v3_g3h is 3v"
Do you mean 3V3_G3H_RTC?
Please, post accurate information.

What is exact PPBUS_G3H voltage (no battery)?
Check U7800 (SYM 1 OF 4) LDOs, page 71.

3v3_g3h_rtc is 3v. ppbus stays at 12.36v . 1v8_slps2r is 0v and it isn't shorted

the board works after replacing four broken coils at the pmic.
