12-Volt DC System
Batteries
The batteries supply electricity for lights, 12-Volt accessories, and engine and generator starting.
The Electrical section of Chapter 8, in the Cruiser & Yacht Owner’s Manual, provides battery, care and
maintenance instructions.
Battery Switches
•
A separate battery switch is provided
for each battery (or battery bank).
•
The batteries supply electricity for
lights, 12-Volt accessories, and engine
and generator starting.
•
Some "Standby Loads", such as the CO
monitors, the automatic bilge pumps,
and the stereo memory, are not affected
by the battery switch since they are
wired directly to the battery (see the
Wiring Diagrams in this Owner’s Man-
ual for more details).
Fuses and Circuit Breakers
•
Fuses and circuit breakers for engines
and main accessory power are on the
DC distribution panels and on the bat-
tery switch panel.
•
Some equipment may have secondary
fuse protection at the unit, behind the
battery management panel or at
the batteries.
•
Electronics power is provided at the
helm station.
•
Never disconnect the battery cables or turn Off the main battery switches while engines are
running as this can cause damage to your boat’s electrical components
