Thanks,

I just have the PSU, sending voltage between the white and black wire should work also ?

Any Capacitor related problem known ?

generally they are not leaking in the psu…  the big issue is the II and Iix mainboard's and trace rot.

Depends on the II motherboard, the first ones used solid caps. If you are lucky to have one no worries. Later revisions switched to the leaky tin trash can caps.

I am not the owner, will ask, but probably should get the whole macintosh for a test.
