SOURCE: need owner's and service manuals for John Deere Model 317/

First off, Mowerman's response was incorrect about the age of a JD 317.  They were made from 1979 to 1982.
You can only get manuals either through here:  http://techpubs.deere.com/deere/Default.aspx  or from a dealer.  They're expensive.  You can find them on ebay and also here: http://www.ssbtractor.com/tractor_manual_display.cgi?m=John%20Deere&o=317%20Hydrostatic but I haven't used that site.

SOURCE: ELECTRICAL PROBLEM

Can't get you a diagram but i can tell you most electical problems on these tractors can be solved by replaceing the key switch/modual or cleaning corrosion from fuse holders.
