Get a cheap digital multimeter/voltmeter. Set it on the 20 volt DC range. With RV plugged into shore power, touch the red probe to the positive house battery terminal and the black one to the negative house battery terminal. You should read 13.6 volts DC if your converter/charger device is working. With RV unplugged from shore power, house battery should read 13.6 volts DC for a while then voltage will slowly drop with lights on, etc. If your batteries are old or if they have been left discharged/dead a number of times or if they have been overcharged and fluid "boiled out" ,they may need replacement. Of course all the connections to the battery must be kept clean and making good electrical contact at the battery terminals. I just replaced the two original house batteries ( two 6-volt batteries in series for 12+ volts) and noticed that the converter/charger was not charging. I ordered a new and much better converter.(Progressive Dynamics PD9245C) Recommend you take your rig to a trusted RV repair place if you are not able to do troubleshooting and replacements yourself. Batteries are very heavy and cost $100 or more apiece, new converter costs around $165, plus tax, and labor for installation.
