Default AcBel API1PC36 PSU

Pulled from an early 2000's PowerMac MDD G4. I've replaced the capacitors discussed in this thread:

The PSU still won't come up; on my bench, jumpering the PSU on causes the fans to spin briefly, and checking the optocoupler at M8 I see 5v, leading me to believe the PSU supervisor is shutting the supply down. I can't for the life of me seem to find anything wrong on the PSU, though.

Would anyone have any suggestions on common faults to check? Anything I might be overlooking? Does anyone know of a schematic for this PSU, perhaps?
