Your Progressive Dynamics converter is a circuit card located in your fuse box under the dinette seat (PD4045). Yours will not support lithium batteries, mine didn’t either. Your hull is the same year as mine. I ordered a new one, it was about $150. It has a switch for lithium batteries. It’s fairly straightforward to switch them out. If I did it you can too. While you are down there, check to make sure your main breaker didn’t flip off. Also, I would check under the bed with your Bluesky for the red circuit breaker to make sure it isn’t off. You might have another one under the dinette seat, I do. Make sure it is set. If you are hooked up to shore power and not getting 110 in the trailer I would suspect one of those breakers broke and needs to be reset (push the little flag back in to place). Hope this helps. Mike
