We have 2 indicated lights for black water and 3 indicater lights for grey water. However, there are only three levers outside to dump, one for black water and two for grey water. What are the two other tanks for and how do you dump them?
I also have a 320 with the same panel. I was told at the pdi that it is a generic panel and that yes there are three tanks and to disregard the other panel lights.
