all lights show full blk water,gray water,propane etc

[IamGadget]

i have a 2004 newmar dutch star
all my tank indicator lights on the panel show full. I know it is wrong especially since i am hooked up and my gray water is open and empty.
all the indicator lights are all lit up. Blk water, gray water, fresh water, LPG, and batt. This did happen once before and then for some reason it corrected itself. I am concerned this time since it has been a while and i know my black water tank will need to be dumped and i do not want it to over fill.. I am still a newbie and fulltime too. Any suggestions are most welcome...Thank you, Allen aka Gadget

If everything went to pot at once I would suspect a loose ground wire either behind your tank indicators or under the coach.

It's not unusual for the black and grey tank indicators to show full even after you dump the tanks, stuff clings to the walls. But if you are sure that your fresh water and LP tanks are not full, you have a problem.
