42 CHAPTER 12: ELECTRICAL SYSTEM

Battery Switches

ENGINE & ELECTRICAL SYSTEM DAMAGE HAZARD!
NEVER change battery switch positions while the engine is running. It can cause damage to
your boat's engine alternator.
Since the batteries on your boat were dealer-installed, the battery switch positions listed below
may vary. Make sure you get a full explanation of battery switch use from your selling dealer.
• Each battery switch has four (4) positions.
• The normal settings are:
Engine battery switch - position "2".
House battery switch - position "1".
• Some "Standby Loads", such as the CO monitor, the auto-
matic 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 in this Supplement
for more details).
• If your boat is equipped with a bow thruster see the Bow
Thruster section of this Supplement for information about
the bow thruster battery switch.
