CHAPTER 12: ELECTRICAL SYSTEM

• 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.
• Have qualified personnel install batteries and/or perform electrical system maintenance.
• Make sure that all battery switches are turned OFF 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.
• ALWAYS run the bilge blowers for at least four minutes prior to engine and/or generator
starting, electrical system maintenance or activation of electrical devices.
• Minimize the danger of fire and explosion by not exposing the batteries to open flame or
sparks. NEVER smoke anywhere near the batteries.
SHOCK & ELECTRICAL SYSTEM DAMAGE HAZARD! NEVER disconnect the bat-
tery cables while the engine is running since it can cause damage to your boat's electri-
cal system components.
Electrical connections are prone to corrosion. To reduce corrosion caused electrical problems,
keep all electrical connections clean and apply a spray-on protectant that is designed to protect
connections from corrosion.
