Alright, I thought I would crosspost this to see if anyone here has one of
these modules. I don't even need to look at this, I remember that the relay
does not kick on at all. I have a DEC jumper that runs across the two molex
terminals on the back of this module that just plugs in.
I didn't think you needed any kind of jumper with this module. The 2 3
pin connectors on the back are for the power control cables to the power
controllers, there's a similar connector on the front that goes to the
frontpanel power switch, and a 4 pin connector on the front to the mains
transformer primary.
Do you have the printset (schematics) for this unit? From what I remember
(and it's been several years...) the power control circuit that operates
that relay is very simple, and you should be able to track the problem
down to a simple component.
