It seems I have yet another failed PSU (fans turn, CPU gives a diagnostic
"F", but DC OK does not come on).
This time from a VAX 4000-300 in a BA440 case. I have not been able to find
a print set or a schematic. Does anyone have such information? Even just the
pinout information for the external connectors so I can connect a test load
to see what is coming out?
How do DC OK circuits typically work?
Regards
Rob
