Sounds like you've solved the problem---for now! So a hint on something that may be helpful?
I have had lots of different RV and each has differing when I spot something that might help search out a problem., locations for all those fuses and breakers, which can really mess up a trip if it blows on leaving home. So I try to head off the gremlins now by looking through all the online diagrams and info the Winn puts online and then when I spot something that seems like it might help solve a problem, I copy that drawing/info to a file on the computer and some I print off and file in the RV.
I find it super helpful, first as a way to get to know the new to me Rv, and second it's much easier to look brilliant when at a campground and just look at the info to solve my problems.
Doesn't mean I don't still have problems but it sure does make it less stress!
Glad to see you found the current solution but I like to think of the next time.
