Monitor gauge readings after fresh water fill?

[wingfoot]

I don't fill my fresh water system very often, only about three or four times since having the RV....This last time I filled fresh water holding tank a strange thing happened. After filling, all monitor values topped out to "full". I, like most RV'rs, don't put any confidence in the monitors but I've never had this happen....any ideas?

Maybe a bad ground wire at the water tank.

OK, thanks for the response. But, I have no idea where to look for the ground wire...any help..anyone?

To get to the wire at the tank, you'd have to drop the coroplast underbelly, perhaps in several areas depending on your trailer layout. Then locate the sensors and inspect the wiring.

The other end is behind the control panel. I've attached a diagram of some of the wiring from a friend's Landmark. Yours might be different, but this may help you figure it out.
