[QUOTE="SweetDoug, post: 1784060, member: 397872"] I actually used to be a mac IS guy back in the 90's, and don't mind watch a Youtube viddy and getting my hands dirty. I've got the thing torn apart right now. I've got power coming into/from the pigtail from the Mac into the board, but nothing on the board. If the PS circuit board back side is facing you--solder connections on the back facing you, on the top right where the plug for the output is, top right, I'm only getting some power at 08, 25.6 volts I think. Is this dead? 15 - 16 13 - 14 11 - 12 09 - 10 07 - 08 05 - 06 03 - 04 01 - 02 SD [/QUOTE]
