The diagram is available for download from the net but there is a small charge!!
Google up"IH 585 wiring diagram" to find the post!!
After months of searching, I finally found the treasure I've searched for! Got a copy of the shop repair wiring diagram from a guy for $25. Well worth it. He has the rest of the shop repair Manuel for my 585 also if anyone needs.
Where did you get it? I need it too.
I also need a electrical diagram for a 585 Case, any chance I could get a copy ?
