Wiring diagrams

One of the things I've been doing recently is documenting Blue Opal's wiring. There's a lot of it, and even though I can label all the cables, sometimes it helps to have diagrams of the connections. I happen to run my own web server, which means I can run my own wiki software that supports Mermaid diagrams - https://wiki.cricalix.net/en/blue-opal/electrics

For those who don't run their own wiki, the Mermaid Live site lets you paste in text like

%%{ init: { 'theme': 'neutral', 'fontFamily': 'monospace', 'flowchart': { 'curve': 'basis' } } }%%
graph LR;
HOU_SWITCH["House Battery Switch (Supply)"];
BAT_NEG_BUS[Battery Negative Busbar];
CAB_NEG_BUS[Wiring Cabinet -ve Bus]

subgraph "BlueSea 4-fuse"
  BSA_STUD(Stud);
  BSA_SALOON(Saloon 3A);
  BSA_CHART(Chart Table 3A);
  BSA_CABINET(Cabinet 1A);
  BSA_STUD --- BSA_SALOON & BSA_CHART & BSA_CABINET;
end

HOU_SWITCH === BSA_STUD;
BSA_SALOON --- SALOON_SW[Companionway Switch] --- SALOON[Saloon Light] --- CAB_NEG_BUS;
BSA_CHART --- CHART_SW[Chart Table Switch] --- CHART_LIGHT[Chart Table Light] --- CAB_NEG_BUS;
BSA_CABINET --- CABINET_SW[Wiring Cabinet Switch] --- CABINET_LIGHT[Cabinet Light] --- CAB_NEG_BUS;
CAB_NEG_BUS === BAT_NEG_BUS;
classDef pos stroke:#f00
classDef fuse stroke:#00f;
class HOU_SWITCH pos;
class BSA_FRIDGE,BSA_AMPS,BSA_PP1,BSA_PP2,BSA_USB,BSA_BILGE fuse;

and get a diagram like this.

The diagram could then be viewed via the Full screen mode, and printed.

For doing actual circuit diagrams, https://www.circuit-diagram.org/editor/ is ok.

The main battery wiring diagram is a bit of a mess still, but I'm not sure I could draw it any better by hand either! Alas, my wiki instance runs an old version of Mermaid; I think the renderer available on Mermaid's live test site is better at the big diagram than what's on my wiki.
