All my tank readings seem to work as they should ( although I only use them for an indicator as I know they can be off a bit) except the fresh water indicator. The javelin monitor shows the fresh water indication as zero (no water) and is flashing. Anyone know the issue how to fix?
You already know how the tank sensors work. Retrace the path you took 2 years ago, and see if anything on the water tank sensors has changed.

Or, upgrade to SeeLevel system. Search the Forum for many "How To" threads.

In my coach, the Javelina system still worked fine, except the monitor was a bit challenging to read due to a constant scroll. Never noticed any flashing on any empty tank readings though. Seems like that could be a useful feature as "notification" that your tank is empty. Does it happen with any of the other tanks when empty or just on the fresh water tank?
I installed a SeeLevel concurrently, that is kept the original as is and installed the SeeLevel as an adjunct. In comparing the readings of the two systems, the SeeLevel is far more accurate and worth the install for that alone. The ability to use Bluetooth for the readings is icing on the cake.
