Hi Gary, Sure wish you would begin writing repair guides and instruction manuals for the Listers. Kent Bergsma of mercedessource.com has done just that for the older mercedes diesels. I have most of his booklets since they are written well enough so that even I can understand and follow them. His daughter, BTW, was the first to suggest to me to take a look at Listers as a source of power and electricity at my place. If you want to look a few of my mercedessource books over, I'd be glad to mail them. Gene
