Fuse issue

I looked at the wiring diagram. What I see is that the instrument panel/cpu is powered by two circuits. A battery circuit which is ON all the time and a switched circuit. Likely ON when the key switch is on.
I think there are more than just the dash lights (aka backlighting) being fed from the blowing fuse. I see a connection to the tail lights and likely other lights
I marked up the wiring diagram to help me understand things better but this is not an exhaustive study.
If you look closely you will see a blue line I added to help me follow the circuit(s).
Since the fuse is now blowing immediately it at least makes identifying the culprit much more certain.
Carefully examining each wiring harness part for signs of abrasion or mouse chewing is necessary.
If you can unplug the tail lights and any other lighting not working when the fuse blows.
Does the tractor start and run normally?

Thank you. Yes tractor starts and cuts fine on the fuse block under were keys are its second one down 15 amp. Before when put in everything lit up and was fine could see fuel level hours etc
By chance have you wash the tractor recently with strong water pressure? If so could you gotten water into fuse box or connections or such? Have you replaced a bulb recently in the circuit that is blowing or switch?
Dave has been kind to post a marked schematic.
In general, one would get a circuit breaker the same size amperage and connector type as the fuse. You can get these at auto stores. Temporarily plug in the circuit breaker for troubleshooting.
Since you have a hard short, it makes it easier to troubleshoot. Isolate the fault by carefully unplugging connectors in a systemic way, using the circuit breaker to indicate location of the fault.

Attach small 12v light bulb (not LED) to blown fuse, now the light bulb becomes the fuse. The light only allows a small amperage to pass thru it and will be full brightness. When you find the short, light goes out.
Thanks to all that responed to my post i tracked down short when fuel pumped was installed wires were under bracket smashed i guess over time was almost seperated and wire finally became exposed put new fuel pump on with wires not under bracket put in fuse all is well now thank you for responding
