The American Boat and Yacht Council (ABYC) has pub- H - 7 STRAY CURRENT CORROSION
lished a standard for the color coding of boat wiring.
Four Winns voluntarily complies with these standards A. General
so the owner of the new boat can install new equip-
ment or troubleshoot the electrical system. The follow- Electrically induced underwater corrosion occasionally
ing table summarizes the color code system
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.
Wire Color
Red
Wire Designation
Wires on positive (+) side of battery that go to
starter. This wire is non-protected.
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
boatsthatareincloseproximitythathaveelectricalpower
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.
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.
Power lead to bilge blower from a fuse or
switch.
Yellow
Sensor wire from tachometer sender to
tachometer.
Dark Gray
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.
Leads to bilge pump from switch.
Leads to auto bilge pump.
Brown/Red
Brown/Orange
Wire between ignition switch and coil. Wire
from ignition switch through distribution
panel to electrical instruments.
Purple
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.
Accessories
Orange
Wire from switch to instrument lights.
Dark Blue
Sensor wire from engine oil pressure sender
to oil pressure gauge.
Light Blue
Tan
Sensor wire from water temperature sender to
water temperature gauge.

Sensor wire from fuel tank level sender to fuel
gauge.

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.
