An open wire between the converter and the RV battery
Loose ground connection
Improper torques
If the converter fuses and AC voltage are good, but the converter output still reads zero volts,
the converter is not functioning prope
Modes of Operation:
13.6VDC range. Batteries are being charged, just at a slower
rate. Converter will not work without AC input.
To get your converter into this mode reduce the load on the system to
almost nothing but the battery. Let the system sit for approximately 44 hours.
Converter voltage will drop to 13.2VDC. If the converter sees any load during this period or
after it is in Float Mode it will revert back to Absorption (Normal) Mode. 13.6VDC.
: Converter will not jump into the “Bulk Mode” unless the battery is below 50%
of charge, or approximately below 13.2VDC output voltage. There is no way to force it to
go into Bulk Mode.
Inspection and maintenance
If the 12-volt power converter is not working (auxiliary battery not being charged) check the
reverse polarity fuse(s) located on the end of the converter.
. If you have further concerns
contact your dealer.
For detailed information on operation and safety, refer to the manufacturer’s owner’s man-
ual.
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 ashes, which
mode is currently being used.
Green LED ashes once per second;
battery is between 50% and 90% charged. Green LED will
ash 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.
Green LED is on solid. Output voltage
is 14.4VDC to rapidly charge the battery up to 90% of full
charge.
: Green LED ashes every 6-8 sec-
onds. Output voltage has been reduced to 13.2VDC; the RV battery is fully charged and
converter is maintaining the charge.
The wizard mode button is used to override the
charge wizard. Refer to the converter owner’s manual for additional information.
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.
