I have a 2016 Unity MB. In the SeeLevel monitor over the door the LP is showing OPn indicating an open circuit. I've looked at the connection on the back of the monitor (green wire leading to yellow wiring) and on the LP tank gauge (clip on with 2 black wires) and the solenoid switch (2 white wires into solenoid on tank). Everything looks secure. I've removed the gauge and cleaned the front and back as well as the fitting that is on the tank. Still it is showing an OPn. Anyone have any idea where I might find this open circuit? I can't seem to follow the wiring sufficiently as too much of it is hidden. Thanks for any help you might have to offer.
