No Charging Current from Converter to House Batteries

Installed two new US golf cart batteries to replace original T-105's in our 2004 Fleetwood Tioga 26Q today. Checked voltage at battery terminals, read 12.4 Apparently not getting any charging current from our original WFCO 45 amp converter which is supposed to have 13.6vdc output. I checked all circuit breakers and fuses including two on the coverter box , the ones in the power panel and fuses in the battery compartment. I cycled the auxiliary battery switch/relay (OK), I checked that converter is getting 120vac at the power panel receptacle on shore power. I pushed pins into the converer charge cables and read 12.4vdc same as at battery terminals indicating continuity to battery but no converter charge output.

Before I pronounce the converter dead, is there something I missed???

As stated above you could take the cover off and see if you can fix it but it would be better to just dump the WFCO and get a smart multi-stage converter. There are direct replacements that are easy to install and your new batteries will be much happier in the long run. Pop a car charger on them to get them back to full charge and keep 12 volts to your rig if needed.

Before I call it dead, I would take the cover off and look inside the converter, checking the terminals and their connections inside the box.

What it read at the terminals without the batterys hooked up? Could they be loading down the circuit?

Same answer as your other 'converter' post

120V AC input.......13.6VDC output measured are terminals on converter where battery cables attach

Not putting out 13.6V DC.......converter bad.
