Power converter is not charging batteries.

[bhuppert]

I have a 2000 suncruiser and this spring i took it out and found my house batteries were almost dead and was plugged in all winter. I ordered and installed a new converter to find out that one is not either. Upon inspecting the old one on the bench it is putting out the specified 13.6 volts. Seems to not be an issue with the converter. Is there a fuse somewhere between the converter and the batteries? Looks like a whole mess of wires in the back of the cabinets that would be almost impossible to get to.

Help please!

I just checked power at the cables that lead from the converter to the batteries and when the converter is disconnected there is 13.45 volts from the battery at that connection point. Seems to not be an open circuit there.....

13+ VDC at the battery, sounds like it's working or the battery is well charged. To check the converter: At the battery you should see the voltage go up about a volt when the converter is on vs. off. If yes, it's working. If not, then check to see if you have 120 vac input at the converter. If yes, then the converter could be bad - or a fuse blown or breaker tripped on the converter. If not, then figure out why no power input to the converter - unplugged, breaker tripped, etc.

RV "converters" convert 120VAC to 13.6 volt DC.... but NOT ALL "converters" are battery chargers.
Which did you install... a "converter"?... a "converter/charger"...OR an "inverter/converter/charger"?

Installed a wf9800 converter 3 stage charger. Have power at outlet to charger.

bhuppert, you could have a high resistance connection between the converter and the battery. With the battery disconnect open will the converter power the coach lights?
Look at all of the connections at the battery disconnect relay and the battery.

Possibility of bad batteries as well. They may not be taking any current.
