Before checking the converter output voltage, it is necessary to
disconnect the battery cables at the battery
. Make sure
the converter is plugged into AC source (105-132 Volts). Check the
converter output voltage at the battery with a voltmeter. Place the
probes on the disconnected 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. Be sure you
have good connections at the cables. If the voltage reads 13.6 Vdc (+/-.2)
with no load, the converter is functioning properly.
If the converter output voltage at the battery reads in the 0.0 Vdc range,
or the battery is not charging, check for:
- an open inline fuse in the battery wire (if installed by OEM)
- 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 properly.
