Wiring Schematics for Pilgrim’s Primary 12V DC System

We have held back posting schematics for Pilgrim’s primary 12V DC system,
until now…

Why now?  Despite spending hours upon hours spread out over months drafting, researching, modifying, testing, modifying, modifying, modifying the schematic, the design continued to evolve throughout the installation.  

The heavy rains that flooded the Carolina's over the past couple weeks provided the perfect excuse for locking myself away inside Pilgrim and completing the primary 12V wiring install.   I plan to pen some additional posts about the install in the near future. 

Initially, I attempted to place both the positive and negative wiring on the same drawing, but the schematic became too noisy and confusing.  The schematics were completed using Google Draw.  If you would like to view the Google Draw files, with active hyperlinks,  use these links:

I welcome questions or comments on the designs.
