NFORMATION
The DC system supplies electricity to all of the
boat’s electrical circuits (lights, pumps, blowers,
ignition, etc.).
The AC system supplies electricity to all of the
boat’s AC-powered electrical circuits (electrical
outlets and to AC-powered systems) when the boat
is moored or moored to a dock or slip.
Some options may be equipped with multiple
batteries. There is a cranking battery for each
engine and a house battery.
There is a battery charger for the house and
cranking batteries. The battery chargers are
powered by either the dockside or generator 120V
AC power.
All batteries are isolated from each other by a
battery switch. When the engines and ignition
switches are off the isolator prevents house battery
loads from discharging the cranking batteries.
When the batteries are being charged by the
alternators, the isolator automatically isolates the
batteries and will distribute the charge among the
batteries according to individual need.
Main Electrical Panel
The main electrical panel is located in the cabin
behind the aft seat back cushion. This controls both
110V AC and 12V DC components.
ELECTRICAL SYSTEMS
DC Electrical
Your Cobalt 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 cabin distribution panel is labeled as
follows:
DC Voltmeter
Cabin Lights
TV/Stereo
Accessory
There are also four indicator lights, one for each
switch.
The 12V DC 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. Two battery switches are
located under the port aft cockpit seat cushion.
Normal settings are starboard set to battery 1, port
set to battery 2. For emergency start only, set
selector to ALL, then return to normal settings.
