When tackling the problem of creation of a wire diagram, I realized that the wiring
was too complex and had too many "sub systems" so in the end I made a series of wiring
diagrams... and these were useful as I re wired each of the sub systems. My diagrams are not standard electrical
schematics using standard protocol and symbols, but for me they are more graphic and easier to read and understand.
I have :
master 12v diagram (engine, charging
, main loads, windlass
, breakers, fuses
110v AC wiring - shore and inverter
Distributions panel (house loads, instrument power)
engine wiring (including engine instruments
, starter alternator)
wiring (instruments and lighting)
The diagrams often include wire color and in some cases length information and are handy when looking at the seeming complex wiring... especially when you can see the start and end point of a wire.
