Sounds like Converter is defective or has power supply 115 VAC or output 13.6 volt DC breaker open or fuse blown. What is voltage at battery with AC on and charger charger not connected? That is the add on BC. It should read 13.2-13.6 with the converter on line. If only 12.+ its not being charged.
Theres a ac circuit breaker in the main panel for the converter supply. There are fuses on the converter one end. Also there is a 12VDC in line fuse usually near the battery in wire from converter. Any open can cause this.
