Checking in ohm scale doesn't help too much.
You should check in diode mode (red probe on ground) and compare with good board.
ADAPTER_SENSE will have same voltage as SYS_ONEWIRE, when U6900 is enabled; so be sure R6929 is good first.
U6900 only joins INT/EXT pins, to allow SMC <-> Magsafe communication.
