AC / DC Line Diagram ( Partial, Mostly )

No, you wont be creating a ground loop. What you really don't want to be doing is having current flow in your engine block. Now some instruments are not isolated so you might get a small amount flowing from them but nothing like the high current from your alternator.

If your starter motor doesn't have a ground terminal directly on it then you will have some current pass through your engine block but only during the time the starter is activated. Not good but nothing you can really do about that.

If your instrument sensors are isolated, so much the better.

Diagram update/revision!

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 etc.)
12v monitor wiring (link)
110v AC wiring - shore and inverter
Distributions panel (house loads, instrument power)
engine wiring (including engine instruments, starter alternator)
NMEA wiring
Navigation instruments
Mast 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.

Excellent!
Thanks for that. Looks very good. I'll have to go follow all the little colored line now ;-)
Seeing what other have done along with their comments is very helpful.

Cheers,
Extemp.

P.S. Would you be willing to share more of your work for example purposes?

Updated Drawings:
Decided to redo the layout over top of the outline of my boat. Turned out to be helpful. Unfortunately the Drawings still lack proper convention. Perhaps that will come.

Make any comments you like!

Cheers,
Extemp.

P.S. Unfortunately even with the highest resolution I could load, there not the best.

Cheer Again!
