Iím having issues with my black tank valve. I donít think itís opening or closing. I canít find a plumbing schematic anywhere. Does anybody know where I could find it? It didnít come with the fifth wheel when I bought it.
You are not going to find a diagram as they do not exist. The dump valve will be close to where you connect the sewer dump hose. You should be able determine if it is moving, by having someone move it while you hold your hand on the valve assy. Be sure you have a hose connected. If it is remotely operated, it is possible that the cable broke or froze if you have had freezing weather.

It has a cable that goes to the valve because it has a sealed underbelly. When I pull the handle it feels like it is working right but nothing comes out of the tank and the tank is full. Kinda stumped.
If it's out of warranty, cut a three sided flap about where you think the valve is and open it by hand, AFTER you have a dump hose connected! Then repair whatever has came loose. Make sure your flap opens to the rear. After you have tidied up in there, reseal the flap with a good allweather tape. Or sometimes there is already a flap that someone else has opened.
I agree with a cable problem. The cable could have become disconnected from either the handle or the valve. On a previous TT of mine the black drain valve would not open very much and took a long time to drain even water. After opening the underbelly I found that the distance from the handle to the valve was less than three (3) feet but the cable assembly was six (6) feet. The outer spring of the cable assembly was wound around two (2) times for some odd reason. When the handle was pulled the circle of the cable assembly would just close up and not allow the wire inside the spring covering to work properly. I just shortened the whole assembly to where it was as straight as possible. It worked fine after that
