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)
SHOCK and ELECTRICAL SYSTEM DAMAGE HAZARD!
When the engine is running, NEVER turn Off the battery switch or disconnect the bat-
tery cables. Doing either could cause damage to your boat's engine and/or electrical
system components.
• 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.

Battery Switch Positions

Since your boat's batteries were installed by your dealer, the battery switch positions listed
