Outside grey tank readout works inside doesn't

Question

Yes, it is another tank sensor question. This one is a bit different. The grey tank readout in the wet bay works correctly. The readout inside the MH always reads full. Haven't pulled the inside panel yet to see if it is something simple like a loose wire. That will happen tomorrow. Suggestions of where to start checking would be appreciated. This question applies to the MH in my signature. Assume that it would apple to many HR/Monaco models around 2007.

Let me know what you find. My inside works correctly but all of the outside reads full.

Here's what I'm thinking...the sensors are working since the wetbay panel gives correct readings. That leaves the wiring and the panel itself. To rule out the panel I would try swapping them. If the problem remains with the inside panel then it's a wiring issue. If the problem moves to the wetbay then it's the panel.

I have the same setup but have not had any problems that would require me to "learn" how this system works. And truth be told, if I had this problem I doubt I would spend time trying to fix it.
