I've been messing around with the Fresh Water tank trying to figure out if the level sensor is bad or dirty, or if the wiring/module is bad.
When I started, I noticed on the display in the wetbay, the tanks levels were showing 20% in the Grey tank, 10% in the Black tank, and 0 in the fresh tank (which was actually about 1/2 full).
Then I drained the fresh tank completely and noticed my Grey tank was now reading 10% full (on the display in the wetbay).
Either the coach shifted enough to change the level in Grey tank (if it shifted it wasn't obvious) when I drained the fresh water out, or somehow the signals are mixing. Is that even possible?
