Does anyone know where a fuse for a sanicon system on 2005 HR Navigator or possibly other high end Monaco coaches of the same year would be located? It ran fine when I winterized the coach, but motor does not start now. May be switch or stuck impeller but need to check fuse first and can?t seem to locate it. I opened black tank and switched on sanicon, now have a mess if I can?t start sanicon. Lesson always check sanicon before opening tank! Any help would be greatly appreciated.
