Kubota B3000 OPC fuse blowing

[j886]

So the 5 amp OPC fuse seems to be blowing more often than not. This only happens when tractor comes to an abrupt stop. This could be hitting snow bank, pile of dirt. And it is similar to if it were to stall due to engine overload, but the fuse blows. I have made the tractor stall from engine overload and the fuse does not blow. It is only abrupt stops or bumping. I even tried bypassing the HST switch, the seat switch and it still blows the fuse. Wondering if it could be one of the PTO switches, relay or the opc controller. I have wiggled every wire on the tractor, from the fuse box to the back. Even banged on the dash and key area hoping to replicate the stall.( blown fuse) I have yet to replicated it other than abrupt stops or bumpy rides. Any ideas would be helpful.

thank you in advance

It sounds like a short to me check to see if you can find any bare
wires

OPC isn't that much to replace,like under $200,I think?

IMHO you should replace the fuse with one that you just push the button to reset
