DC Wiring Color Codes
Color codes identify wiring throughout the boat. The color codes for the DC system is as follows:
• Red – Source Conductors
Positive 12VDC. All current carrying conductors between the batteries and first switch or load device in
a circuit. Bus bars, circuit breakers, terminals, and fuses in the source conductor are not considered
switches or load devices.
• Yellow – Negative Conductors
All current carrying DC negatives that terminate at the batteries or their terminals.
• Green – All Ground Conductors
Non-current carrying grounding and bonding conductors.
There are several additional basic colors and color combinations for different circuits used beyond the
ignition switch. Some of these colors can serve more than one type of circuit. Table 3-4 illustrates the
color codes for the engine compartment and battery wiring.
