On boats with both AC and DC systems, the DC system is generally simpler. Wire colors will assist you in doing that, even if they don't follow ABYC standards, by helping you identify the far end where it reappears from a conduit or a locker on its way to the equipment it powers. Trace each wire in the circuit from the electrical source to its use. Make no assumptions about which wires do what.

The wiring colors on your boat may be very different, especially if it's older and there's been a lot of 'jury rigging' in its past. Your diagram should have one line for those three enclosed wires, except as necessary to differentiate them at the ends. You'll see the colored individual wires when they exit the common sheathing at each end. Those three wires typically are enclosed in white or gray insulation. ColorĪC wiring for 110 volts usually has white for neutral, black for hot, and green for ground (220-volt AC lines have a second hot wire, colored red). Wires and components associated with each should be distinct and, on newer boats built to American Boat and Yacht Council (ABYC) standards, will use standard color-coding. In recently built boats, the two systems should be clearly differentiated and separated, including at the electrical panel. Serious damage and even electrocution can result from confusing the two. On many boats there are two types of current: alternating (AC) and direct (DC). Eventually you'll have a map of your entire electrical system and a thorough understanding of how the pieces are tied together. With each wire you trace, and circuit you complete, it gets easier. Start by focusing on the simpler (and safer) 12-volt DC system aboard your boat. You won't get it all done in a day - or even several weekends - and don't let yourself get intimidated by complex electrical diagrams. Making your own isn't rocket science, but it does take time, patience, and care. The older your boat, the more likely you are to have either no wiring diagram or one that's worse than none because it's inaccurate.
