I swapped a 180 watt brick with a 135w one. Then I took the 135 watt brick and hooked it up to a Powermaster which is now feeding power to all the accessories. After that was up and running, that freed up the last circuit I was using on my ZW, so it's ready to be removed from service.
Of course I was "testing" the new configuration, so I didn't want to unhook any wires from the ZW while the trains were running So for now the ZW is still in place with wires hooked to it.
