M9000 Without power to switch

[WilberMaker]

I have an older cab-less M9000. Everything working parked it next day will not start. Jump power on the starter and turns over fine. I have power to the alternator and the flashers will work. Unplugged the key switch and not getting any power to any of the four wires. Checked the 50amp slow fuse and shows continuity. At a loss on what to check next. Also can anyone point me to a wiring diagram for the M9000. Don't seem to find one on the list. Thanks for the help.
