Yes. Your converter is shot. Replace it.
You followed the correct testing procedure according to the WFCO users manual (here:
). See bottom of page 5 where is says:
"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."
I had the same converter and had the exact same problems. AC circuits worked fine but DC circuits were dead, and upon testing, the DC output at the battery was - - guess what - - 0.4v - - same as you.
Before I did the testing I figured it was just a dead battery, but a new, fully charged battery was dead one week after installation. Also interesting, I had been fighting a propone detector that had been going off intermittently, even when propane was shut off at the tanks. A new charger/converter solved ALL those problems.
WFCO ... is ... junk ... in my opinion. Replace with a good brand like Progressive Dynamics. I got mine from bestconverter.com. Great service, great price, great product. I got the drop-in replacement unit and it only took around 30 minutes to make the swap.
