To Disconnect:
• Shut off each individual breaker first then shut off the boat’s
main AC circuit breaker.
• Turn off the dock breaker.
• Disconnect the dock end of the shore power cord first.
• Clean and dry the shore power cord. Store it in a dry location on
board the boat.
You are now disconnected to shore power
Low Emissions Generator
The optional onboard generator can also provide AC power to your
boat’s electrical system. AC power output, in kilowatts, will vary,
depending on the Cruiser’s needs. The control panel for the genera-
tor is on the main panel in the cabin. Located on this panel is the
blower switch for generator. Switch must be on before starting gen-
erator and left on while generator is running. Before turning on the
ship circuit breaker to energize the AC system with the generator,
test the polarity of your system as described in the Shore Power
section of this manual. Always be sure that the raw water seacock is
open before starting generator.
Note: See the generator instruction manual for detailed infor-
mation about safe operation and proper maintenance.
Lighting
Lighting operates off the 12 volt DC system. Turn lights on or off at
the main electrical panel in the cabin or at the light fixture. See your
Chaparral dealer for information regarding bulb replacement.
Ground Fault Interrupter Outlet
The ground fault interrupter outlet provides protection against cur-
rents which can be dangerous even though they do not overload
circuit breakers. These outlets which have a test and reset switch in
the middle of the faceplate provide ground fault protection to the
head and galley outlets on the boat. If there is a difference of more
than 5 milliamperes, a safety switch trips in the outlet and interrupts
the circuit. This protects the person who is operating the electrical
equipment from serious electric shock or loss of life. The outlet may
not eliminate the feeling of an electric shock, but it does open the
circuit quickly enough to prevent injury to a person of normal health.
When the outlet’s circuit breaker is tripped, you must push the
RESET button. Check this outlet periodically by pushing the TEST
button. Pushing the TEST button cuts power to the 120 and 220
volt outlets. Chaparral recommends replacing GFCI’s once per
year by a qualified electrician.
Electrolysis and Zinc Anodes
Many boaters are unaware of the problems associated with electroly-
sis and how to properly address corrosion issues. Electrolysis is a
reaction between metal and electrical energy. Electrolysis occurs when
electrical current is "leaking" into the water, and can come from a vari-
ety of things such as ship to shore power, sharing electrical wires, old
electrical devices in contact with the water, batteries in boats, etc.
Electrolysis can also be caused by “stray currents” due to a fault in
an electrical item, even though correctly grounded. Chaparral boats
with shore power are equipped with a galvanic isolator which iso-
lates the boat from the dockside electrical system.
Electrolysis/corrosion is a very real issue and expense for any
boater and boat owners must be aware of the proper protection and
maintenance. Corrosion will directly affect the performance of your
boat within a very short period of time.
