So was the last thing that corrected the lights, flashers, headlights, the fuse?
No, there were several other corrded point withing the harness. There are several points where a single 10g wire is spliced into two 12g wires using just some soldering and tape. Those splices were also corroded leaving multiple breaks in the wiring harness. Not too big of hassle just had to make sure to remove the entire conduit and trace the wire from one end to the other.

I have a 2009 M7040 ROPS that is having the same issue... We were using the tractor all day for spraying with no issues. Switched it off to talk before we headed back to the house for the night, tried to start to drive home and there was no power to dash and no start. Checked the fuses and had a 15 amp fuse blown (second fuse from the bottom), replaced the fuse but still no power to the dash and no start. I have checked voltage at the battery and starter and both are 12.7V, checked the slow blow fuse (still good), and replaced the ignition switch but still nothing... Any help would be greatly appreciated!

Thanks
