Here's a few possible makeups for 5 wire DC systems, plus detail drawing of a 3 wire DC Generator.

Discussion thread for this topic is existing in the General Discussion area under the name:

Historical systems



5 Wire DC System, using two separate 2-wire DC Generators, with a balancing Grounded Conductor - acting as a "Floating Neutral". The Grounded Neutral is common to both Generator circuits by the Series-Parallel connection of the Resistors.



Similar to the system above, except using Batteries for the DC power source.



5 Wire DC Interconnected Systems, using two separate 3-wire DC Generators.
Grounded Neutral Conductor is common to both Generator circuits by physical common connection between "Upper" Genny's "-" lead and "Lower" Genny's "+" lead.
Voltages found at various points are listed on the left side of Schematic.
For simplicity, the Generators are shown with output voltages of 10/20 VDC. Also, only the Armature windings are shown.



Similar to the System above, except using Batteries for DC Power source.



Simple detail of a 3-wire DC Generator.
