Any idea what would be causing my black tank monitor level to always read EMPTY? I started getting this reading only at the interior panel, now I'm getting it at both the interior and exterior monitor panels. Just got back from Canada, New England and Indiana, so not sure if something "worked loose" during the trip or not.....
