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 recreation vehicle 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 tow vehicle alternator when the engine is running and the
7-way trailer plug is connected. This powers the RV's running lights, brake lights, turn
signals and brakes. In addition, the 7-way trailer plug provides a common ground and
a 12-volt charge line to charge the auxiliary battery.
The converter will supply interior 12-volt DC power when the power cord is plugged
into campground power. The converter will also charge the RV battery in most
situations. (Refer to Battery Disconnect)
The auxiliary battery powers many interior 12-volt components including the lighting
fixtures, water pump, 12-volt motors, 12-volt appliances, etc. It also powers the
breakaway switch.
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.
