12-Volt DC System
Batteries
The batteries supply electricity for lights, accessories, and engine starting.
The Electrical section of Chapter 8, in the Sport Boat 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 Switches
• Each battery switch has four (4) positions.
• Some "Standby Loads", such as the CO monitor,
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 Dia-
grams in this Supplement for more details).
Alternator
The engine alternator will keep the batteries properly charged when running at cruising speeds.
