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. Whether you want to install a new stereo system or trace an intermittent electrical fault, a wiring diagram will save you hours of aggravation.
