Electrical System - Bayliner 3388 Owner's Manual Supplement

6 CHAPTER 3: COMPONENTS / SYSTEMS

Electrical System

We strongly recommend that you read and understand this section and the Electrical Section of the Owner's Manual.
Wiring diagrams are provided in this manual supplement for use in troubleshooting electrical problems.
• To minimize the risks of fire and explosion, NEVER install knife switches or other arcing
devices in the fuel compartments.
• NEVER substitute automotive parts for marine parts. Electrical, ignition and fuel system
parts were designed and manufactured to comply with rules and regulations that minimize
risks of fire and explosion.
• DO NOT modify the electrical systems or relevant drawings.
• Only qualified personnel should install batteries and/or perform electrical system maintenance.
• • • • Insure that all battery switches are in the OFF position before performing any work in the
engine spaces.
• Fuel fumes are heavier than air and will collect in the bilge areas where they can be acci-
dently ignited. Visually and by smell (sniff test), check the engine and fuel compartments for
fumes or accumulation of fuel. Operate the bilge blowers for at least four minutes prior to
engine starting, electrical system maintenance or activation of electrical devices.
• Minimize the danger of fire and explosion by not exposing batteries to open flame or sparks.
It is also important that no one smoke anywhere near the batteries.
SHOCK/ELECTRICAL SYSTEM DAMAGE HAZARD!
• Never disconnect the battery cables while the engine is running as this can cause damage to
your boat's electrical system components.
• The battery charging systems (alternators and battery charger) 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.
• Electrical connections are prone to corrosion. To reduce corrosion caused electrical prob-
lems, keep all electrical connections clean and protect them with a spray-on protectant such
as Corrosion Guard
• VOLTAGES - All boats use either 110-volt AC/60 Hertz, 240-volt AC/60 Hertz or 220-volt
AC/50 Hertz single phase systems, and 12-volt DC or 24-volt DC. Electrical distribution
panels are labeled with voltage and frequency of AC and DC.
