If its not an AC problem:
You can’t charge house batteries from the converter you say, but with use/store “off” does the converter power the DC lights and fans in the coach OK? Yes, means converter AC inputs/DC output is probably OK and you might have an open 50 amp mini re-settable breaker tripped between the converter and coach batteries (typical picture attached; note the arrow – not necessarily specific to your coach though). In some coaches that mini breaker is located under the bed close to the converter/breaker panel......but I am not familiar with the 2017 ACE at all, or which battery management system it uses. If you find the mini breaker reset it by pushing in the small black button.


If that mini breaker is not the problem, does the use/store latching relay operate OK (you hear a clunk when it operates or turns off?). Do DC lights and fans work off house batteries when the shore and gen are disconnected/off? No, could mean a failed coach battery latching relay.
