ELECTRICAL SYSTEM
Your yacht is equipped with two electrical systems: a battery-powered
direct current (DC) system and a generator or shore-powered
alternating current (AC) system. Both systems are controlled from the
AC/DC master panel.
The DC system supplies power to all of the yacht’s 12-volt electrical
circuits (lights, pumps, blowers, ignition, etc.).
The AC system supplies power to the 120/240-volt systems when the
yacht is moored at the dock or slip, or when the generator is running.
Circuit Breakers
Circuit breakers wear faster if they are used as an ON/OFF switch.
Turn off the equipment the breaker protects prior to using the breaker.
Arcing at the contact points in the breaker damages the contact
points.
Constant breaker tripping signals a problem, which means something
in the circuit requires attention or the breaker is bad. DO NOT attempt
to make the breaker engage when the breaker constantly trips.
Have your authorized Cruisers Yachts Dealer determine the fault. An
overheated breaker can fuse the contact points and the breaker will
not be functional. Allow the breaker to cool. If it continues to trip,
check the current draw. Check the breaker by allowing it to cool down.
Turn the equipment off, and after the breaker cools, engage the
breaker. Then, turn the equipment back on. Place your finger on the
front of the breaker and note the temperature. If it does not heat back
up again, then the problem was probably the overload from start-up of
the equipment. If the temperature rises again, the fault is in the circuit
or the breaker. A breaker can also overheat when breaker contact
points become eroded.
DC Electrical System
Your yacht has a 12V DC house system. The positive wire is hot, and
feeds current from the batteries to the various 12-volt systems, and
the negative wire is the ground.
Some yacht and engine options may be equipped with up to five
batteries. There is a cranking battery for each engine or there can be
two batteries in parallel for 12-volt house power: a generator battery
and an optional bow thruster battery. Not all yachts offer this as an
option.
When the engines are running, all batteries are charged by the
alternators. There is a battery charger for the house and cranking
batteries and an optional battery charger for the optional bow thruster
battery. The battery chargers are powered by either the dockside or
generator 120V AC power. The generator battery is charged by the
generator.
The DC system wires are identified by three colors. Red wires are +12
volts, yellow wires are DC common and gray wires are DC control
wires. Bonding wires are green. AC system wires utilize three colors.
DANGER
A glowing red polarity light indicates that a reversed
polarity electrical shock hazard exists and damage
to appliances will occur. DO NOT use shore power
while the red light is on. Disconnect the shore cord
and have the shore outlet serviced by a qualified
electrician before using.
DANGER
Considerable care has been taken to design a safe
electrical system to protect you from hazardous
shocks. Any modifications to the system should
always be done by an authorized Cruisers Yachts
Dealer not only to protect your warranty, but to protect
you from hazardous shock as well.
