Macbook A1466 820-00165 Intermittent Fan Spin

[Instafixx]

For my reference SSRB2
Device came in certain resistors misisng. R5115 etc.
Installed them back.
Now i get magsafe and random fan spin for 1-2 seconds.
Draws upto 300mAh and drops and again up.

PPBUS is 8.59.
PM_SLP_S4_L is missing.
ALL_SYS_PWRGD pulsing as well.

Fan can't spin if PM_SLP_S4_L stays low.
Trigger SMC_ONOFF_L and check for drop pulse at PM_PWRBTN_L.

Did you try SMC bypass?
