820-3662 on power

Good afternoon, this mac had a shorted capacitor C7324 causing the PPbus to short, I replaced it but the PPBUS is at 5V.
The Vcore resistance is 10 Ohms, too low?

Voltage: PPbus: 5V; pp3v42 3.42V; ALL_SYS 0.223V pulsing; Vcore 0V;

ALL_SYS_PWRGD pulsing, but PPBUS_G3H 5V steady?

10 ohm doesn't look bad, but you should compare with similar board.

Check/replace C7125.
What is R7120 voltage?

I replaced the isl6295 and the SMC removed from the 820-00163 board, in tests at PPbus 12.3V
I wonder if the SMC board 820-3332 works on board 820-3662 ?
