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 Sport Boat Owner’s Manual provides battery care and
maintenance instructions.
Battery Switch (If Equipped with Two Batteries)
• 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 batteries
(see the Wiring Diagrams section of this chapter for
more details).
• Turn the battery switch to the Off position whenever
your boat will be unoccupied for long periods of time.
