Bathroom electrical

2017 Jayco 33RBTS It started with ceiling led puck lights flickering and progressed to shut down after seconds. Now, the fan randomly works and black water sensor indicates from empty to full w/in hours, which is impossible. Any thoughts?

Check your connections at the battery. Then with the power off check the connections to the breakers. Look for corrosion or loose wires.

Only a guess on my part , never happened to me but corrosion on connections can do weird stuff.

Oops, left out. Look for the ground from the fuse/breaker box to the frame. It may be under the RV and take a little crawling or even bottom cutting to find it. Try wiggling wires and see if you get flickers.

Welcome to the forum.

I agree with RogerR. It's probably corrosion and I suspect it's on the ground side of your 12v system. Bad ground problems often create weird symptoms.

If you get your trailer's wiring diagram from Jayco, that may be a help in resolving your problems.
