12-Volt DC System

Batteries

The batteries supply electricity for lights, 12-Volt accessories, and engine starting. The Electrical section of Chapter
8, in the Cruiser & Yacht Owner's Manual, provides battery, care and maintenance instructions.

Battery Switch

• Never disconnect the battery cables or turn Off the battery switch while the engine is run-
ning as this can cause damage to your boat's electrical components
• The batteries supply electricity for lights, 12-volt
accessories, and engine starting.
• 'Standby Loads', such as the automatic bilge
pumps, and the stereo memory, are not affected
by the battery switch since they are wired
directly to the battery.
• Turn the battery switch to the Off position when-
ever the boat will be unoccupied for long periods
of time.

Fuses and Circuit Breakers

• Fuses and circuit breakers for the engine and main accessory power are on the DC distribution panels and on the
battery 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.

12-Volt Accessory Outlets

DO NOT use the 12-volt accessory outlets with a cigarette or cigar lighter. High temperatures
may melt the outlets.
• These outlets can be used with any 12-volt device which draws 15-amps or less.
• The 12-volt accessory outlets are protected by a 15-amp circuit breaker on the main circuit breaker panel.
