Changed trackpad and flex already. Was minor water damage but not there trackpad or keyboard areas.
keyboard has 3.3v at pin 30
and 3.4v at pin 4
trackpad has 5v pin 4 and 3.3v at pin 1
at one stage when testing pin1 on trackpad I touched ground too and it shorted and I had to replace r4808 when it shorted though the keyboard stared working.
put r4808 back and no keyboard again.
Keyboard pin 5 smc_onoff_l is 3.4v
