Fuse F101 blown in JD 6810

[Spanish]

Can someone tell me why the 30A F101 fuse that corresponds to the supply of the battery terminal to the engine blows on my JD 6810 tractor?

Curiously, it melted when the tractor was stopped on the grain warehouse weighing scale, when I got on the tractor. Any contact, electrical shunt ...?

Is that the engine stops suddenly

I had an issue similar many years ago on a 6800. It took some time to find, but was caused by a replacement self tapping screw in the plastic cover over the dashboard. It was 5mm too long and over the years it had vibrated into the wiring loom until one day it caused a dead short.
