DC ELECTRICAL
Your Cobalt 360 boat has a 12-volt negative
ground DC system. The positive wire is hot, and
feeds current from the batteries to all 12-volt
equipment; the negative wire is the ground.
The DC electrical system panel in the cabin
supplies electricity from the house battery to:
● Cabin lights
● Galley lights
● Head
● Fresh water pressure pump
● Refrigerator/freezer
● Air compressor
● Entertainment System
● Radar
The 12 VDC system consists of a voltmeter, a
main circuit breaker and a series of switch-type
circuit breakers. The voltmeter allows you to check
the condition of the batteries.
Three battery switches are located under the port,
aft cockpit seat cushion. Normal settings are
starboard set to battery 1, port set to battery 2
and the house/generator set to battery 2, which is
its independent battery bank consisting of two
batteries located on the port side of the engine
compartment. For emergency start only, set
selector to ALL, then return to normal settings.
Circuit breakers under the switches are for items
as labeled, helm, amp, trim tabs, bilge pump, and
distribution panel.
The bilge pumps are wiring direct to the battery
through BILGE PUMP breaker and will remain
energized even if battery switches are turned off.
All other items, including the CO monitors, will be
disabled. DO NOT OCCUPY BOAT IF CO
MONITORS ARE DISABLED.
A voltage sensitive relay is mounted next to the
battery switches and automatically allows the
starboard engine alternator to charge the house
batteries.
To operate the 12 VDC system:
● Turn the battery switch labeled capacity
HOUSE/GENERATOR, located under the port
aft cockpit seat, to position 2.
●
Switch the DC main circuit breaker to ON
position. Indicator light next to the switch will
illuminate.
● Activate the individual component circuit
breaker.
