Battery

The battery supplies electricity for lights, 12-Volt accessories, and engine and generator 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 & 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.
• "Stand-by Loads", such as the automatic bilge pump,
and the stereo memory, are not affected by the battery
switch. Stand-by loads bypass the battery switch and
are wired directly to the battery.
• Turn the battery switch to the Off position whenever
the 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
