Looking for Cummins ISC 8.3 owner's manual

Hi, does anyone have a pdf for the ISC 8.3? I'd be interested in the "Operations & Maintenance Manual", "Owners Manual", and the "Wiring Diagram" documents.

I actually have a C-series manual that I'm happy to provide a link to, however it was printed in 1993 so it doesn't have ISC info.

Give this a shot:

Let me know if you have issues opening it.

Edit: Forgot to mention, the basic owners manual is available for free online from Cummins.

Thanks a ton for this one. I bought a CD off ebay but the content quality is much much worse than this one!!
