How to read and understand the schematic diagrams

Hey guys,

I'm trying to learn how to repair MacBook water damaged by my own.

I'm really good in the cleaning process using ultrasonic professional cleaner and most of the times it solve the problems.

But I want improve my understanding.

Actually, I'm stuck in a repair project of two MacBook A1278. Both won't turn on.

I'm quite good with soldering procedure, and I replaced some SMD that commonly become burnt after water spill.

I would like to learn how to read and understand well the Apple schematic diagrams.

Especially how to test the voltage of the "critical" power rails, like PP3V42_G3H power rail e.g.

If some expert will be so nice to write a quick guide, I think it will be helpfull for a lot of people like me.

I'm also available to help and find link, photos ecc, to make a professiona l guide if some one is interesting in do it. Maybe at the end could become a book, and we can publish it.

So everyone is interesting to start guide me in the understanding process, put me on the right direction. I will appreciate it a lot. After that we can also discuss to prepare a real pdf guide or book.
