Since you just replaced the batteries I would start by checking the 2 reverse polarity fuses on the converter.

Thanks

Thanks guys was able to get Thor on the line, went thru some stuff everything started working again after we ran the generator. Gal from Thor was awesome and now things seem to be working correctly. Sounds like something in the Firefly system that just needed to be reset, will see how things go on the rest of the trip. Thanks Dan

this larger coaches don't use Converters, only Inverters...with integrated battery chargers. The 12v system simply draws from the batteries while the batteries are being charged - no converter needed.

and yes, my own Inverter's 20amp fuse popped out recently, while we were running too many plug in heaters, and then the microwave - popped and lost all 'power', though it was not the shore power that was the problem, just the Inverter's fuse. Pressed it in and everything was great again.
This is the Inverter's 'pass thru' fuse, to keep too much 120v power from the shore coming thru the smaller wiring from the Inverter's output back to the breaker panel's sub-panel for all the outlets.
