CHECKING FOR REVERSE BATTERY HOOKUP (REVERSE POLARITY FUSES)

If there is no DC output coming from the WF-9800-AD 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.
