If you can get to the senders at the top of the tank check to make sure both wires are still hooked up and connections are good. If that checks out pull the gauge wire and touch it to the ground wire. The gauge should read full if wiring is good and power is coming to sender.
If gauge reads full the sender is bad. If no reading then you may not be getting power from sender.

That gauge is notoriously unreliable. I gave up on mine a couple of years ago and put markings on the tanks at 1/4, 1/2 and 3/4 full. I just stick my head down into the lazarette and look at the tanks to check water level.

Maybe a stupid question, but is the fresh water pump on? Mine doesn't work unless the fresh water pump is turned on.

Hidden in-line fuse? (Ours has one.) Loose connection at the sensor or at the display?

If it's a WEMA in-tank sensor, their newer stainless version, it's pretty simple, not much to break.
