Re: More circuits then color code charts cover
Real easy. You only need two colors. Use red for positive. Use black or yellow for negative. Do that for each 12VDC circuit.
Most sailboats have wires running to:
1. an anchor light atop the mast;
2. a steaming light on the forward side of the mast, used when under power; and
3. spreader lights.
Some sailboats in addition to the above may have 12V wires for:
4. a deck light, used to light the foredeck; and
5. a tricolor lamp atop the mast.
It's a very good idea to label each wire, so you know where they go.
