Electrical System
DANGER
CAUTION
NOTICE:
Generators charge the battery just enough
to compensate for the DC electrical current
the engine requires to operate. Therefore,
it is important to activate the battery char-
ger to maintain the batteries whenever the
generator is running.
NOTICE:
The generator used in your boat may not be
able to operate all 120-volt accessories at
the same time. POWER MANAGEMENT PRAC-
TICES may need to be observed depending
on the AC power load.
GENERATOR ENGINES PRODUCE CARBON MONOXIDE
WHICH IS A LETHAL, TOXIC GAS THAT IS COLORLESS AND
ODORLESS. IT IS A DANGEROUS GAS THAT WILL CAUSE
DEATH IN CERTAIN LEVELS. ONLY OPERATE THE GENERATOR
IN WELL VENTILATED AREAS AND NEVER OPERATE THE
GENERATOR WHILE YOU ARE SLEEPING.
4.6 Bonding System
and Galvanic Isolator
Your boat is equipped with a bonding system that
interconnects all underwater hardware and thru-
hull fittings to ensure that they are of the same
electrical potential. Anodes are attached to the
bonding system at the trim tabs and engines.
There is also an anode in the seawater cooling
system for the generator and on the bow thruster
propeller if these options are installed on your
boat. The anodes deteriorate before the other
metals, thereby protecting the underwater metals
from galvanic corrosion or stray electrical current.
Since the anodes are sacrificial, it is important to
monitor them and replace them when they have
deteriorated to 50 - 75% of their original size. The
bonding system is connected to the DC ground
and the earth ground wire for the AC electrical
system. It provides a path for dangerous short
circuits in the AC electrical system to the safety
earth ground in the event of a fault in the shore
earth ground connection and when the boat is
away from the dock.
When the boat is connected to shore power at a
marina or city dock, all boats connected to shore
power are connected to a common shore safety
earth ground connection. This circuit provides
essential protection against electrical shock from
faults or short circuits in AC equipment and, unfor-
tunately, provides a path for low voltage galvanic
current to flow between the bonding system of
other boats in the circuit. If one or more of the
boats in the circuit has a stray current electrical
problem or is not equipped with proper galvanic
protection, it will seek protection from your boat’s
bonding system through the safety ground circuit.
This could cause accelerated deterioration of the
anodes and/or severe damage to the underwater
hardware. To prevent damage from other boats
in the circuit, a galvanic isolator is installed in
the shore ground circuit that isolates your boat’s
bonding system from the other boats. It prevents
the flow of low voltage galvanic current while still
providing a path for dangerous short circuit cur-
rents in the AC system to the shore safety ground.
4.7 Electrical System Maintenance
12-Volt AC Electrical System Maintenance
At least once a year, spray all exposed electrical
components behind the helm and in the plugs, with
a protector. Exterior light fixture bulbs should be
removed and the metal contact areas coated with
a non-water soluble lubricant like petroleum jelly
or silicone grease. The sockets should be sprayed
with a protector. Care must be taken not to get
any oil or grease on the glass portion of the bulbs
as this will cause the bulb to overheat and burn
out. Note that LED lights are sealed and cannot
be serviced.
WHEN REPLACING LIGHT BULBS IN MARINE LIGHT FIXTURES,
ALWAYS USE A BULB WITH THE SAME RATING AS THE
ORIGINAL. USING A DIFFERENT BULB COULD CAUSE THE
FIXTURE TO OVERHEAT AND MELT OR SHORT CIRCUIT.
Inspect all wiring for proper support, sound in-
sulation, and tight terminals, paying particular
attention to portable appliance cords and plugs.
Check all below deck wiring to be sure it is prop-
erly supported, that the insulation is sound, and
that there are no loose or corroded terminals.
Corroded terminals should be thoroughly cleaned
with sandpaper or replaced, tightened securely
and sprayed with a metal and electrical protector.
Inspect all engine wiring.
