I am trying to locate any informatioin regarding the output specifications of the Bard 4400 ESA such as tolerance and load required.   A service manual would be nice, if available.  Anyone have any ideas?

Did anyone have a service manual or at least a schematic? I have a unit that shows Return Electrode Fault after initialization step. Any suggestions?
