Black Water tank level indicates

[Hunter]

In the 305 RL system control panel there is 2 operating indications light marked #1Bk and #2Bk. There is only one holding tank and value control. Am I missing something here? Gray water has two holding tank and value controls

Sam,

Welcome to the forum!

The panel is universal. The rigs with two heads have a second black tank.

Thanks tank 2 reads 2/3 full with no tank. How would that work. I guess disconnecting would not hurt anything. Thanks again

You will soon find that the black tank sensors are pretty much useless and soon begin to read improperly. Most of us just know when we need to dump and never look at it. Years ago we paid for outside the tank sensors on our 2010 and they worked great, but I never used them so we haven't sprung for them since.
