I have water damage logic board # 820-3536-A .

I have water damage logic board out of my late 2013 MBP ratina. I am testing through power rails and I am checking my PPBUS_G3H power rail with multimeter. I am getting below finding.

I am getting 12.59v for all R5410,R5400,R5440,XW5480,F7700,R3080,C3080,F7140

except this two I am getting 0.05v

R5400 = o.ov

Q3080= o.ov

Can anyone tell me why I am getting 0v for above . anything short in between or what ?

Any information will be greatly appriciate.

We should deal with the water damage first. That may fix the issue, and if you don't address the water damage, you'll have bigger problems.

I have already took out all the parts and bath my logic board with 91% alcohol and let it dry for almost 48 hours and I dont find any mold or anything on the logic board . I have two liquid which turn into RED now but other than that nothing else.
