40 CHAPTER 12: ELECTRICAL SYSTEM
12-Volt DC System
Batteries
The batteries supply electricity for lights, accessories, engine starting.
The Electrical section of Chapter 8, in the Cruiser & Yacht Owner’s Manual, provides battery, care and
maintenance instructions.
Fuses and Circuit Breakers
•
Fuses and circuit breakers for engines and main accessory power are on the DC main distribution panel and on the
battery switch panel.
•
Some equipment may have secondary fuse protection at the unit, behind the battery switch panel or at
the batteries.
•
Electronics power is provided at the helm station.
Battery Switch
•
The battery switch has four (4) positions.
•
Some "Standby Loads", such as the CO monitor, the auto-
matic bilge pumps, and the stereo memory, are not affected
by the battery switch since they are wired directly to the bat-
tery (see the Wiring Diagrams in this Supplement for
more details).
