Time for an Electronics for Dummies question...
If I have a center negative power supply (the diagram shows that the
negative is in the center of the connector) does that mean the center of
the connector on the device to be powered should be connected to the
ground plane?
Usually the ground plane is negative but not always. The best way to
check is to use a VOM and measure the resistance from the center
connector to the ground plane. I hope this helps.
