Dual Power button not working

[Emmet 7810]

I started the day with dual power and everything working perfect no loads on the 7810 at all that day i parked in the town for 5 mins and came back tried reaching high dual and the button did nothing im hoping its maybe a fuse or lose connection somewhere

any help or tips much appreciated
7810 gen 3 digital dash
no previous problems with this.

Also would anyone be able to explain to me what all of these images are I dont have a service book with her so most of them dont make sense to me

If the switch is in the floor check the screw hasn’t un done had this a couple of times. Switches also go check it out

Button on floor well and truely tight have that checked only 1 fuse i found to be blown its the one circled would that have any correlation to the issue? guessing maybe not.

You will have to test switch is getting power and check switch function with a multimeter

Is that hard to get access to or work at if theres an issue there?

To check live if you look at bellhousing just in front of right side there is a single wire with a male terminal about 2in long with a rubber grommet protruding from top of housing its connected to a another single wire pull apart, ign on use a meter and check live from female connector if none use d/p switch check again if none either switch or fuse, to check d/p use a live feed from battery to male connector should spark and you should hear a click if none coil burnt out, to check d/p leave wire off drive tractor stop join wire and try again you should feel a difference if ok d/.p ok, normal for switch to fail if long arm needed.as it bolts to floor remove cap first [grub screw], if it's coil come back.
