This has me puzzeled! I can't find a transer switch anywhere, or any infromation on this coach. It seems that it's an orphan unit as Mallard Industries went out of busness in 92 and the John Deer, Oshcosh frame divisions sold to Freightliner around the same time. Any information as to the position of the transfer switch or if maybe it switches in the converter would be greatly appreciated. Also any other information regarding the unit.
