Default Black Tank

We, too, have a Sun Voyager with similar reading problems as you do. After dumping, connect the garden hose to the outside line leading into the tanks. Close the black tank valve and fill with a lot of water. Empty. Repeat process. Then keep the valve open a run the water into the tank. It will spray into the tank. This usually does it for me. Also, we just returned from NY State and traveled with a few gallons in each tank. Boy, did it clean out the black! I'm also assuming that your rig has the water line into the tanks so you can work from the outside.
