BTW, I had the same issue with the flashing gauge but in my case the problem was the connection at the tank and not the gauge. Sounds like I am in the minority though. So if this fix doesnít work then you might want to check the wad of wires on top of the fuel tank and behind the fuel caddy door and double check all of their connections.
Also, I have problems about 90% of the time with my fresh water holding tank level gauge too. Something tells me the same idiot connected all those wires on my rig. The guys at the factory need to be trained on how to properly connect things because you canít blame the equipment if it is not installed properly. This is the first rig I have ever had where the gray and black tank levels work great but the fresh water tank only shows full while filling but then when you get to camp it reads the lowest level. I would check the connections on the tank myself but I donít feel like trying to pull the cover that encloses the tank from the bottom to do it. I now gauge my fresh by the levels of my gray and black tanks and know if they are 1/3 or so full each that I still have tons of fresh water left!
