The drawings at the end of this chapter show the typical locations of
system equipment.
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
illustration.
ELECTRICAL SYSTEMS
Your Chaparral boat has a 12 volt, direct current (DC) battery 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. The voltmeter on the instrument panel in the dash
shows the battery charging rate when the engine is running.
The negative terminal of each battery is connected to the grounding
studs of the main engine(s). This type of negative ground system is
the approved system for marine DC electrical systems. If you add
additional equipment to your boat it must be adaptable to the nega-
tive ground system.
NOTE: A fuse block near the helm has been provided with addi-
tional accessory hookups. Consult your Chaparral dealer for
additional DC power needs on your boat.
Note: The appropriate fuse must be used. Consult a qualified
technician for proper fuse size.
Battery
Note: A dual battery system is optional equipment on some
models.

safe electrical system to protect you from hazardous shocks.
Always have a qualified technician make any modifications to
the system.
