If the converter output voltage at the battery reads 0.0 VDC, or if the battery is not 

charging, check for an open inline fuse in the battery wire circuit. One may have been 

installed by the RV manufacturer. Also check for loose wiring connections.

Reverse Polarity Fuses

If there is no DC output coming from the WF-8855E Series Converter-Charger output lugs, 

first check the reverse polarity fuses on the rear panel. Then, visually inspect the fuses for 

any breaks in the fuse element. If no breaks are found, use a continuity tester to check for 

continuity. If the reverse polarity fuses are blown, it means the RV battery was accidentally 

connected in reverse, either at the battery or at the converter. Investigate the connections 

and reconnect the cables properly. Replace the fuse with the same type and amperage rating 

as the original.

IMPORTANT: 

These fuses protect the converter from damage if the RV battery is             

accidentally connected in reverse. A reversed battery connection, even if for only a second, 

will cause these fuses to blow.

If the above checks have been made but the converter output still reads 0.0 VDC, the      

converter is not functioning properly.
