Holding Tanks

[RX7NOROTOR]

Hello everyone,
Quick question on my holding tanks. I have a 2003 monaco windsor and wint to winterize but one of the tanks is almost full still. I jave on my panel "HOLDING TANK 1" "HOLDING TANK 2" and "FRESH WATER TANK". I figured out the fresh water tank but with my grey and black empty, I still have almost a full holding tank 1. Anybody have similar coach know which tank is which?


Thanks
Greg

You only have 3 tanks: Gray, Black, and Fresh.
It's very possible one of your tank quantity sensors is faulty. They are pressure transducers and easily clogged, especially the black sensor.
They are easy to change. Look at Northwest RV Supply for new sensors.

Open the Cargo Door opposite (passenger side) your WetBay . You should see the backside of your holding tanks. The first pic is a picture of my previous coach a 02 HR Imperial that is probably similar to yours. Note the strips taped to the sides of the tank. These are sensor strips. Mine were barely functioning. The second pic is what I replaced them with (Seelevel 709, I think). https://www.garnetinstruments.com/wp...chure-0419.pdf
