Converter w/charge wizard (if so equipped)
Some converters may be equipped with a charge wizard There are (3) possible charging
modes; NORMAL, BOOST and STORAGE. The charge wizard will automatically select
the best mode to charge your battery. A green LED next to the wizard mode button will
indicate by flashes, which mode is currently being used.
NORMAL MODE: Green LED flashes once per second; battery is between 50% and
90% charged. Green LED will flash 2-3 times per second; battery is 90% charged. Output
voltage is 13.6VDC and the converter is safely completing the charge of the battery.
BOOST MODE: Green LED is on solid. Output voltage is 14.4VDC to rapidly charge the
battery up to 90% of full charge.
STORAGE MODE: Green LED flashes every 6-8 seconds. Output voltage has been
reduced to 13.2VDC; the RV battery is fully charged and
converter is maintaining the charge.
MANUAL MODE (Not recommended): The wizard
mode button is used to override the charge wizard. Refer
to the converter owner's manual for additional information.
REVERSE BATTERY PROTECTION: Reverse polarity
fuse(s) provide protection for the converter when a battery
is used. If the battery is connected backwards to the fuse
board a fuse will blow preventing damage to the converter.
Four easily accessible fuses are located next to the wizard
button. Replace with fuses of the same type and rating.
12-volt DC System
The majority of your motor home lighting is powered by 12-volt electricity. The 12-volt DC
system is composed of components that will operate when the following conditions are met:
Power is supplied by the chassis alternator when the chassis engine is running.
The power converter will supply interior 12-volt DC power when the shore power cord
is plugged into a 120-volt external power source. The converter will also charge the
house batteries in most situations.
The house batteries power many interior 12-volt components including the lighting
fixtures, water pump, 12-volt motors, 12-volt appliances, etc, when the motorhome is
not connected to a 120-volt power source.
12-Volt Fuse Panel
Replacement fuses must be of the same voltage, amperage rating and type.
Never use a higher rated replacement fuse; doing so may cause a fire by
overheating the RV wiring.
The 12-volt fuse panel is labeled to indicate fuse sizes, positions and the components
powered. Fuses are located in the load center.
