I can not start my Agco Allis 5670 A. Serial 1803. It was working fine two days past and I shut down normally.  Now there is no response when I turn the key. The battery tests fine. None of the dash lights show. 
I was able to pull the ignition switch and all wires there seem to be okay.
I am suspecting a wire under the tractor has disconnected from one of the safety circuits that prevent starting the tractor in gear or with the PTO operating.
Is there somewhere I can get a diagram as to which wires go where?
