An open inline fuse in the battery wire

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
rly.
Modes of Operation:
Absorption (Normal) Mode:
13.6VDC range. Batteries are being charged, just at a slower
rate. Converter will not work without AC input.
Float Trickle Mode:
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.
Bulk Mode
: 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.
Red LED indicates blown fuse.
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.
There are no customer serviceable parts inside the converter case and the manufac-
turer’s warranty will be void if the case has been removed
. If you have further concerns
contact your dealer.
For detailed information on operation and safety, refer to the manufacturer’s owner’s
manual.
Converter with Charge Wizard (if so equipped)
Some converters may be equipped with a charge wiz-
ard There are (3) possible charging modes; NORMAL,
BOOST and STORAGE. The charge wizard will auto-
matically 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 re
-
duced 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.
