The electrical system is engineered and tested for safety. Circuit breakers and fuses
protect the electrical circuits from overloading. If you plan to make modifications or
additions to the electrical system, Four Winds International/Mandalay Luxury Division
strongly recommends consulting a certified electrician for assistance to ensure
continued integrity and safety of the electrical systems. Please note that any
modifications may void the Limited Warranty.
The electrical power supply provided for the motorhome is a dual operating system with
120 Volt AC and/or 12 Volt DC. The 120 Volt power may be provided by either connecting the
motorhome to an outside power source when parked, or by use of a motorhome generator.
When the 120 Volt system is operational, power also passes through a system inverter,
allowing the full use of all 12 Volt functions in the motorhome.
120 Volt appliances in the motorhome include the refrigerator, ice maker (optional),
air conditioning, TV's, DVD player, microwave oven, inverter, washer/dryer (optional), and the
water heater. The refrigerator and water heater also have the option to run on Propane Gas
when 120 Volt is not available. All other lights and functions are supplied with 12 Volt power.
When it is not possible to access 120 Volt power, the 12 Volt system functions can be
supplied by the coach batteries. The chassis battery is protected by a battery isolator
controller to prevent discharge from excessive electrical consumption when the motorhome is
not running. The coach batteries are recharged by the power inverter when the motorhome is
attached to an outside 120 Volt power source, or by the generator when it is running, and by
the chassis alternator when the chassis engine is running.
