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.
Make sure your selling dealer fully explains how to use the battery switch.
• 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 (see the Wiring Diagrams section of this
chapter for more details).
• Turn the battery switch to the Off position whenever the boat will
be unoccupied for long periods of time.

Battery Switch Positions
