to get the power supplies working. If you've got a missing/low power

Sure, but the thing is, the PS seems to be fine when there's no logic
plugged in. It puts out -15VDC right on the money. When I connect all
the mate-n'-locs to the logic cage, the voltage dies down severely.
Doesn't that indicate a 'logic' problem? Or at least a short somewhere on
the logic boards?
I'm going to try plugging in only one power jumper at a time,
testing after each one. Maybe that'll trim down the area the short's
coming from... Please stop me if this is going to blow something up. I
don't know what else to try at this point...
