ELECTRICAL FEATURES
GENERAL INFORMATION
Th ere are two electrical systems in your Allegro Breeze motorhome. Th ese are the 12-volt DC (VDC)
system and the 120-volt AC (VAC) system. Most standard appliances require the 120-VAC system,
while the majority of the lighting systems used in the Allegro Breeze use the 12-VDC electrical system.
Th e electrical power for the 12 VDC system is supplied by the batteries of the Allegro Breeze. Th ose
batteries are charged by a power converter. Th e alternator also charges the batteries when the engine is
running.
Th e electrical power for the 120 VAC is supplied by the power cord when the Allegro Breeze is connect-
ed to an external power source or when the on-board electrical generator is in operation. Th e convert-
er/inverter can also supply 120 VAC electrical power (to limited outlets and limited appliances)—the
inverter transforms the 12 VDC electrical power from the batteries into the 120 VAC electrical power
for the basic appliances.
To connect the Allegro Breeze to an external source of 120 VAC electrical power, it is fi rst recommend-
ed that all of the circuit breakers are in the “o ff ” position. Th is is done to prevent any power surge
upon connecting the motorhome to the external power source. Th en unwind the power cord from the
electrical compartment located in the compartment behind the driver’s-side rear tires. Th e standard,
fl exible, power cord supplied with the Allegro Breeze is designed to handle up to 50 amperes. Make
sure that the pins in the male end of the plug are oriented correctly so they match the power cable, and
they are in good condition (i.e., aren’t bent or damaged).
If there is a circuit breaker switch at the “plug” end of the power cord, that breaker should be turned
“o ff ” before making the connection. Insert the plug into the mating outlet and then turn the circuit
breaker “on.” Close and lock the electrical compartment door to protect the contents and to keep them
clean and dry. Close the cover on the power box, if so equipped, to avoid an unintentional disconnec-
tion and to keep the contents clean and dry. Th en switch the main breaker to the “on” position.
When properly connected, the 120 VAC system provides power to all the 120 VAC circuits and outlets
when the main breaker is turned “on.”
CAUTION
Failure to turn off the 120 VAC appliances
when starting or stopping the generator may
damage the transfer switch and/or electrical
appliances.
