unknown switch anyone know what it is
I have a thor Mandalay, actually a Four winds by Thor, which is pretty loaded and in the wet bay there are three switches. Two are pretty simple and work fine. The third is labeled "DUMP" on or off. I cannot figure out what is dumping or if it works. My gray and black tanks have a manual pull handle located in the wet bay. They both dump fine no matter what position the dump switch is in.
Does anyone have any idea what this switch is for?? I have pulled the panel and it is wired up with the wires going into a bundle.
