SYSTEMS 3
3-1
This chapter discusses the various systems needed to make your
Chaparral Cruiser a home away from home. These include the elec-
trical, fuel, fresh water, and sanitation systems and related
equipment. The drawings at the end of this chapter show the typical
locations of system equipment for boats with twin and single
engines, respectively.
Note: For location of items listed in this chapter, refer to the
respective drawing. Depending on how your boat is equipped,
the location of some items may be different than shown in the
illustrations.
Note: The term “engine” in this chapter means one or two
engines, depending on how your boat is equipped.
ELECTRICAL SYSTEMS
Your Chaparral boat has two electrical systems: a 12 volt, direct cur-
rent (DC) battery and a 120 or 220 volt alternating current (AC)
system. An optional generator or the shore power connection pro-
vides power to the AC system.
Safety Precautions
Follow these precautions when working with or on electrical sys-
tems or electrically powered equipment:
1. Shut off power supply before starting work.
2. Use insulated mats to prevent accidental grounding.
3. Make sure clothing is dry. Keep skin dry.
4. Remove all metal jewelry.
12 Volt DC Power
Batteries are the source of power for the 12 volt DC (direct current)
electrical system. The batteries are charged through the engine-dri-
ven alternator or the optional AC (alternating current) battery
charger. The voltmeter on the instrument panel in the dash shows
the battery charging rate when the engine is running. Power from
the battery is supplied through the selector switch in the stern area
of your boat. Exceptions to this power supply are the forward and aft
bilge pumps, refrigerator, macerator, and the windlass. Breakers for
these items are near the battery selector switch in the engine com-
partment for the Signatures 370, 350, 330, 310, 290, and 270. All
DC power is distributed through the battery selector switch.
The negative terminal of each battery is connected to the grounding
studs of the main engine(s) and generator. This type of negative
ground system is the approved system for marine DC electrical sys-
tems. If you add additional equipment to your boat it must be
adaptable to the negative ground system. Chaparral supplies a fuse
block at the helm for additional electrical equipment.
Note: Consult your Chaparral dealer for additional DC power
needs on your boat.
