JD 5425 , died while running, no start, has power to lights , f1 fuse blown - at a loss now

[TimmyO52]

Tractor **** off when running, would not start, no power to ign switch, found f1 fuse blown replaced and popped again immediately while switch was turned on , turned switch off, replaced fuse and blown a second one when turned on, pulled console, and removed switch, replaced f1 fuse, no power to switch hub in harness, battery is good, fuseable link good, f1 checks good, but no power to switch, was originally thinking switch was bad but after checked power in hub nothing, jump selenoid and cranks, no power to dash gauges etc, at a loss? Is there an ignition relay somewhere? I also tried unplugging the temp sensor but fuse is not blown now, power on both ends of fuse with test light, but no power to switch, plug switch back and turn and nothing now, not blowing fuse or have power at all to switch.

Something made fuse blow. Going to guess there is a damaged or bare wire somewhere. Putting fuse in a few times may have finished the job so it's not running current anymore.

I was thinking maybe switch was bad, removed switch and tried to jump the terminals on switch to see if the switch was the issue but now no power to the switch hub

I would suggest to clean all electrical conections because over time
they get corroded
