Gray tank readings

[RayandWendy]

2014 Anthem. Until last week the gray and black readings were always good. About a week ago the gray started acting up, after about 14 to 18 it would jump to 76 to 82 and stay there until the tank actually got that full and would continue on normally. Black reading fine always. I did some searching and found suggestions for 12v reset, did that, no change. Suggested cleaning tank since we were in location for a month. Before we moved I put a gallon of Pine-sol and about 10 gallons of water in the tank for the trip. Dumped upon arrival and still the same readings. Also, readings are the same inside or out.
Any suggestions?

The 14's were great for the sensors to come loose from the tank. I reapplied mine with clear silicone. There are several post dating back to the Classics with the location and solutions.

I will have to find some of those posts. Thanks.

Ray, here's a link to a document on my Google Drive that has info pertaining to the tank sensor system: https://drive.google.com/file/d/1q1c...ew?usp=sharing

The tank sensor info starts on page 17 and includes location of the tank probe sensors.

Take care,
Stu

Stu,
Thanks, I already had that document but did not realize it showed where the sensors actually are.

I have removed all the mounting screws on the wet bay panel, got the hose reel out of the way but still cannot move the panel more than an inch. Am I missing something or do I just have to try and access the sensors from under the panel?
