Need help with 3 & 5v points and MS issue

[enixidfrag]

Ok so i'm working on a VERY BIG project. But I need help with two pieces

#1 I need the 3v & 5V Spots so i can do the rumble mod

#2 I desoldered the MS slot and and at one point i had it working but its no longer working i had to reolder a few times now i'm not sure if maybe a fuse blew or something for the MS and if so idk where it is.

3v:

For the positive on the powerboard, you must take an exacto knife or something sharp and gently remove the green layer revealing a layer of positive copper

5v:


About the memory stick problem- Do you have a picture?

That contact on the powerboard is actually 3.6 volts and not just 3 I think. I'm not too sure about the memory thing either.

I actually get 5 volts off the powerboard...

And make sure there is no bridging in the Memory slot reader.
