Does anybody has or knows a RH8851 Air-conditioning test box for sale?
I've run into serious airco problems and in the TSD4200 manual al testing is done with the blasted test box.
Eventually a detailed electric circuit diagram might serve to build one.
I realize this request is quite old, but since I've run across it I thought I'd post a link to the Flying Spares web page where you can rent this test box. There is a very substantial (and justified) non-return/broken return fee of approximately $800 US on this unit. The rental fee as of today's date is 50 Pounds Sterling.
If anyone knows of other rental sources, these things are hard to come by, so please post.
