Chapter 11: Electrical System
Fuses and Circuit Breakers
• Fuses and circuit breakers for engines and main accessory power are on the DC distribution panels and on the bat-
tery switch panel.
• Some equipment may have secondary fuse protection at the unit, behind the battery management panel or at
the batteries.
• Electronics power is provided at the helm station.
12-Volt Accessory Outlet(s)
DO NOT use the 12-volt accessory outlet with a cigarette or cigar lighter. High temperatures
may melt the outlet.
• Your boat features one or more 12-volt accessory outlets.
• The outlet can be used with any 12-volt device which draws 15 amps or less.
• The 12-volt accessory outlet is protected by a 15 amp circuit breaker on the main circuit breaker panel.
Alternators
The engine alternators will keep the batteries properly charged when running at cruising speeds.
Battery Charger or Inverter/Charger
The battery charging systems (alternator and battery charger or inverter/battery charger)
installed on your yacht are designed to charge conventional lead-acid batteries. Before
installing gel-cell or other new technology batteries, consult with the battery manufacturer
about charging system requirements.
• Before using the battery charger or the inverter/battery charger, read all instructions and cautionary markings on
(1) the battery charger or the inverter/battery charger, (2) the batteries, and (3) all appropriate sections of the
battery charger manual or the inverter/battery charger manual.
• The battery switches do not need to be On when using the battery charger or the inverter/battery charger.
• You may use DC powered electrical systems, such as the lights and stereo when the battery charger or the inverter/
battery charger is On, but there will be a corresponding drop in charger performance.
