This section of the manual includes information

about your boats AC and DC electrical systems

and components. Please note that this manual

does not designate equipment as standard or

optional. Some equipment is not available on

some models. Have all service performed by a

professional electrician. See your dealer for

electrical schematics or if you have any other

questions.

WIRING COLOR CODE

The American Boat and Yacht Council (ABYC)

has published a standard for color coding of

boat wiring. We voluntarily comply with this stan-

dard to simplify installing new equipment or

troubleshooting the electrical system. Here is

the color code system:

RED wire is used for the positive (+) side of the

battery in DC systems on wires that go to fuses

or circuit breakers, to distribution panels and

high-draw equipment (engine starters), start

ignition switches and to meters.

YELLOW WITH RED STRIPE wire is used on one

circuit only; from the starter switch to the

starter solenoid.

NOTE: There are 10 basic colors and color com-

binations for different circuits used beyond the

ignition switch. Some of these colors, however,

can serve more than one type of circuit. For

example, they can be used in engine and non-

engine circuits.

YELLOW wire is used for the power lead to the

bilge blower from a fuse or switch. It is also the

color used for the wire from the generator or

alternator field terminal to the field terminal on

the voltage regulator.

DARK GRAY wire is used for navigation lights

and wire between the fuse or the fuse and the

lights. It is also the color used for the sensor

wire from the tachometer sender to the gauge.

BROWN wire is used for leads to the bilge

pumps from fuses or switches.

PURPLE wire is used between the ignition

switch and the coil and from the ignition switch

to electrical instruments through the distribution

panel.

DARK BLUE wire is used for instrument and

cabin lights. These wires run from switches or

fuses to the lights.

LIGHT BLUE wire is used for the sensor wire

from the engine oil pressure sender to the oil

pressure gauge. The pressure sensor most

likely will be three wires — a light blue wire

from the sender, a black negative wire to the

ground or return and a purple hot wire from the

switch or fuse.

TAN wire is used for the wire from the water

temperature sender to its gauge.

PINK wire is used for the sensor wire from the

fuel tank’s sender to the fuel gauge.

GREEN wire is used for bonding wires and nor-

mally does not carry current.

The table on the following page lists fuses and

circuit breakers on your boat. The location of

breaker panels varies by boat model. The

breaker panel is usually at the helm or in the

engine room. Check with your dealer if you can-

not find the panel. Your boat will not have all the

fuses and breakers listed.

12-VOLT DC ELECTRICAL SYSTEM

Your boat’s 12-volt DC system obtains its power

from a battery. An engine-driven alternator

charges the battery whenever the engine is run-

ning. An automatic battery charger keeps the

battery charged whenever your boat is con-

nected to shore power. The voltmeter on the

electrical load center indicates the charging

level of the battery.

The electrical system ground is GROUNDED by

grounding the batteries to the engine(s). The

auxiliary batteries (if so equipped) are in turn

Considerable care has been taken to

design a safe electrical system to pro-

tect you from hazardous shocks. To

protect from hazardous electric shock,

always have a qualified technician

make any modifications to the system.
