SYSTEMS AND COMPONENTS
This section provides information about your boat’s
electrical system, instruments, controls and other
equipment.
NOTE: Some of the equipment described in this chapter
may be standard for some models and optional or not
available for other models. Check with your Lund dealer if
you have questions about boat equipment.
ELECTRICAL SYSTEM
Your boat’s electrical system is a 12 volt, direct current
(DC) type similar to the system in an automobile. A battery
or batteries supply power to the system. The battery is
charged through an engine-driven alternator. A voltmeter
at the helm dash shows the charge level of the battery. DC
circuit breakers, also at the helm dash, operate 12 volt
equipment and protect it from power surges. Turning the
ignition switch off does not cut power to all components.
The battery’s negative terminal is connected to the engine
grounding stud. This type of negative ground system is the
approved system for marine DC electrical systems. The
main feed has an inline fuse in the battery compartment.
The electrical system is wired at the factory to handle
factory-installed electrical equipment. recommends that
you have your dealer install any additional equipment. An
error in wiring the electrical circuits can cause a fire or
damage electrical system components. Have your dealer
repair the electrical system and install additional
equipment.
If you do add additional equipment, it must be adaptable to
the negative ground system. When installing additional
equipment be sure to take the power supply from the
circuit breaker panel. Be sure to protect all electrical
components from rain, water or sea spray.
