C. Reverse Polarity Indicator
Improper grounds or reversed polarity at shore power
are a source of serious electrical hazard. The reverse
polarity light will indicate if a problem exists at the 120
AC electrical system shore connection.
Push the black test button and the red reset button
should pop out from the inner surface. The receptacle
and the circuit are now off.
Push the reset button in until it clicks to reset it. If it
does not reset, there is either a short in the circuit or
the equipment being used, or a ground fault in the
equipment. Unplug all appliances and reset the GFCI.
One at a time, plug the equipment back in and turn it
on. The item that causes the GFCI to trip is the
problem item and should not be used.
If a problem exists, the reverse polarity indicator light
will come on when the shore power cable is attached
to the inlet. DO NOT activate the shore power switch
in the cabin when the reverse polarity light is on.
ALWAYS check the reverse polarity indicator
light in the AC distribution panel immediately
upon connecting the shore power cord before
turning on the AC SHORE POWER circuit
breaker. If the light is on, a problem with a
reversed electrical connection exists.
Disconnect the shore power cord immediately.
Notify the marina and have the dock’s shore
power connection inspected.

A generator is standard on the V375 models. It
provides 120 Volt (220V) AC power when the boat is
away from the dock. The generator can be operated
while running at or below cruising speed. The genera-
tor should not be operated when the boat is being run
at high speeds. Insufﬁcient cooling water may be
available due to the speed.
Under proper operating conditions, the reverse
polarity indicator light will not be on. A green light is
provided for the shore power and will be “ON” when
dockside power is being used.
A generator factory installed by Four Winns is capable
of providing sufﬁcient power for most electrical needs
including cooking, refrigeration, and air conditioning.
It is possible to overload the generator by trying
to operate too much equipment at one time. The
circuit breaker that protects the output circuits on the
generator set will trip should that occur. See the
generator manu facturers information for speciﬁcations
and additional details.
Some marina shore power systems may be
improperly grounded to retard electrolysis
(see Section H-11 - Stray Current Corrosion).
Before using any 120 volt equipment, make
sure the reverse polarity light does not activate
when connecting the cord to the inlet.
If you wish to use dockside power, be sure the
generator is off, connect the shore power cords as
explained in Section H-8A, and turn on the Shore
Power breakers on the AC cabin panel. If you wish
to use generator power:
D. Ground Fault Current Interrupters (GFCI)
The ground fault current interrupter (GFCI) is a device
which protects against hazardous electrical shock
from improper ground. An appliance electrical cord
with worn insulation or damp equipment may have
stray current which will run through electrical grounds.
Stray current as above will result in an electrical
Be sure the shore power cord(s) are disconnected.
Check the bilge for fumes, operate the blower for
at least 4 minutes, and verify blower operation.
Open the generator’s seacock valve (labeled
GENERATOR) to allow water ﬂow to the genera-
tor for cooling purposes.
One GFCI receptacle will protect all of the receptacles
on the circuit. A GFCI may be used as a receptacle as
well as an interrupter.
