Converter Output Voltage
Before checking the WF-9800 Series Converter-Charger output voltage, disconnect the
battery cables at the battery. Make sure the converter is plugged into an AC source (105-
130 Volts). Check the converter output voltage at the battery with a voltmeter. Place the
meter probes on the discon-nected battery cables; place the Positive (red) meter probe on
the + Positive red battery wire and place the Negative (black) meter probe on the
-Negative black wire on the battery cable (Figure 3). Be sure you have good connections
at the cables. If the voltage reads 13.6 - 14.4 VDC (+/- 0.2) with no load, the converter is
functioning properly.
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-9800 Series Converter-Charger output lugs,
rst check the reverse polarity fuses on the rear panel. en, 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: ese 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.
