The American Boat and Yacht Council (ABYC) has pub-
lished a standard for the color coding of boat wiring.
Four Winns voluntarily complies with these standards
so the owner of the new boat can easily install new
equipment or troubleshoot the electrical system. The
following table summarizes the color code system:
Note: Some of these colors can serve more than one
type of circuit.
Wiring Color Code
Wire Color Wire Designation
Red
Wires on positive (+) side of battery that go to
starter. This wire is non-protected.
Red/Purple
Stripe
50 amp protected wire that runs from the engine
to the fuse panel at the helm.
Yellow with
Red Stripe
Wire from starter switch to starter solenoid.
Yellow
Power lead to bilge blower from a fuse or switch.
Dark Gray
Sensor wire from tachometer sender to tachometer.
Brown/Red
Leads to bilge pump from switch.
Brown/Orange
Leads to auto bilge pump.
Purple
Wire between ignition switch and coil. Wire from
ignition switch through distribution panel to
electrical instruments.
Orange

E - 5 STRAY CURRENT CORROSION
A. General
Electrically induced underwater corrosion occasionally
affects boats and their related components. This is re-
ferred to as “Stray Current Corrosion” and appears as
surface pitting or deterioration. Stray current corrosion
is the decomposition of chemical compounds by electric
current.
Stray current corrosion can be caused by the polarity of
the dockside wiring system of the boat being reversed
from the power source (reversed polarity) or surround-
ing boats, an improperly wired battery installation, other
boats that are in close proximity that have electrical power
leakages, or any other source close to the boat that has
electrical power leakage into the water. Stern drive units
are especially vulnerable to stray current corrosion.
Periodically inspect the drive components and thru-hull
fittings to determine if stray current corrosion damage
exists. If corrosion damage is found, determine and cor-
rect the cause of stray current to prevent further dam-
age. Consult an experienced marine electrician or con-
tact your Four Winns dealer for assistance.
The use of some shore power battery chargers, while
the boat is in the water and the battery is connected to
the system, can cause stray current corrosion. Have an
experienced marine electrician review any battery
charger installation to ensure a stray current corrosion
problem will not develop. An improper battery connec-
tion is a common cause of stray current corrosion.
NOTICE
Use only “Coast Guard” approved battery charg-
ers. Consult your Four Winns dealer for his rec-
ommendations.
Corrosion is usually more prevalent in polluted or salt
water than in clean water. It is also more likely to occur
when dockage is in an area with steel piers, large metal
boats, or where shore power is in use.
B. Galvanic Corrosion
Galvanic corrosion results from a potential electrical dif-
ference existing between dissimilar metals immersed in
a conductive solution (e.g., salt water). If these metals
touch or are otherwise electrically connected, this po-
tential difference produces an electron flow between
them. The attack on the more active metal is usually
