Thor Sequence 2025 20L black, grey, propane tank gauges all read empty. Fresh tank reads correctly. The black tank will intermittently show a level. The unit has a VegaTouch Mira panel. Does anyone now the location of the control unit where all the wires would connect to is? I am assuming bad connections there.

I have a BMPro system on a Gemini. However the fresh water tank would only read when full (would not read the 1/3, 2/3 reading) but the grey and black water tank worked fine. In this system the resistance to ground is measured for the three water tanks (fresh, grey, and black). Each tank has a resistor network wired to the sensor locations. Unfortunately this type of circuit is not verified to be good by the OEM or the dealer. Here is what three water tank sensors look like. You can test these by shorting each sensor pin to ground ( it is like a one minute test).

The tanks have small metal contacts, usually 3-4 on the side of the tanks. It isn't usually those, but check anyways. Connections might be ok, but impossible to see if sensors are ok. Then check connections at relay or panel.
It's usually the inability of the readout to interpret or even work at all. The BMPro is useless. Mine was reading grey tank as full, when it was not.
So I installed the SeeLevel system- sensors live on the outside of the tank.
Benefit mostly was having a pump switch by the bathroom, and over my bed, so i could just reach up and turn on/off. Without that- it's wake up the BMPro, and go to touch switch for the relay (masternode) and listen. I had to change switch from normal SPST to SPST momentary (for relay switching in my 2022 Tellaro), and piggy back off the rear switch wires on the back of the wardrobe- accessible from RR cargo door only. (I added wallpaper too...)
