I have a 2000 42' AC which has the vacuflush monitor in each head. The red light signify full is on all the time. Not sure where to start in troubleshooting...any suggestions on where to look first?
Thanks,
Ed
 
this model has the level also in the electrical panel and it shows empty or blank. Its empty but there is a float? Guess I need to find it as the tank is below the gen.

Look on top of the tank and you will find very small white wires. Follow them along the top of the tank and they will end up into a probe with a float on the end....

you would think the same float would operate both gauges. Must be 2 floats.
