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 surrounding
boats,animproperlywiredbatteryinstallation,otherboats
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.

50 amp protected wire that runs from the
engine to the fuse panel at the helm.

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.

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 damage.

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 ex-
perienced marine electrician review any battery charger
installation to ensure a stray current corrosion problem
will not develop. An improper battery connection is a
common cause of stray current corrosion.

to oil pressure gauge.

dockage is in an area with steel piers, large metal boats,
or where shore power is in use.

Gray/Green
Gray/Blue
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 poten-
tial difference produces an electron flow between them.
The attack on the more active metal is usually increased
and the attack on the less active metal is decreased, as
compared to when these metals are not touching.
Note: Some of these colors can serve more than one type of circuit.
