Well, you could ignore one of the more important systems on the coach, or repair the problem so it never happens again. The problem is the design of the MicroTrend tank indicator sensor. It is basically a threaded bolt with a rounded head that goes into the tank in 4 places. While it "won't catch toilet paper" as some think, it will short out to the wall due to the tiny insulator ring between the bolt head and the wall itself (which conducts electricity due to slime on the wall).
This thread is how I solved my tank indicator problem.
