4600 SCB Owner’s Manual Supplement
Parallel Battery Switch
• An emergency crossover (parallel) switch at the helm enables you to start an engine using both engine batteries if
the designated engine battery is low.
• To use the parallel mode, make sure both battery switches are turned ON. Hold down the parallel switch while
cranking the engine. Once the engine has started, release the switch.
Battery Charger
Your yacht is equipped with a battery charger. We recommend that you thoroughly read and understand the battery
charger manual before using the charger.
• The battery charger will charge the yacht’s batteries whenever the boat is plugged into 120 volt shore power or
while the generator is operating.
• The battery charger can be accessed through the aft bulkhead access panel in the aft berth.
• The battery charger’s circuit breaker is located on the AC panel and must be turned on for charging to occur.
AC Electrical System
Your yacht uses 120v/60Hz or optional 240v/60Hz AC (alternating current)
systems.
Τhe AC system can be energized by shore power, generator
power or optional inverter power. This system is designed so that ship’s
power and shore power sources cannot supply power simultaneously.
The AC panel is located on the port side of the salon, outboard of the aft
berth steps. The AC panel’s master circuit breakers provide power source
selections to the accessory breakers that are directly below the designated
master breaker.
SYSTEM DAMAGE HAZARD!
• NEVER disconnect battery cables or turn off battery switches while the engines or optional
generator is running as this can cause damage to your boat’s electrical components.
• The parallel switch should only be used in an emergency.
CAUTION!
!
The battery charging systems (alternators and battery charger) are designed to charge conven-
tional lead-acid batteries. Before installing gel-cell (or other new technology) batteries, consult
with the battery manufacturer about charging systems requirements.

NOTICE
Accessories that are powered by the optional inverter have white-colored AC panel breakers.
• The simultaneous operation of several AC accessories can result in an overloaded circuit. It
may be necessary to turn off one accessory while operating another.
• WATER HEATER DAMAGE HAZARDS! DO NOT energize the AC water heater electrical
circuit until the heater is completely filled with water. Even momentary operation in a dry
tank will damage the heating elements. Warranty replacements will not be made on elements
or tank damaged in this manner. The tank is full if water flows from the tap when the hot
water is turned on in the galley.
CAUTION!
