Hello. Im just getting into the Mac world. I picked up a G4 2x533 and it has a dead PSU. I took it apart to find some dark/black solder marks and removed the resister that it was connected to. It doesn't look healthy and only had a value of about 100ohms. The color bands were really hard to read cause so charred. Im pretty sure it was red/white/red/gold or red/yellow/red/gold. So 2400 or 2900ohms. I was wondering if anyone had a schematic I could verify this with. Any other help would be great. I knew the PSU was bad cause there was nothing on the +28v wire.
