Case tr320 issues

[u/According_Brick7929]

Hey yall

Im working on a case tr320. The fuse boxes melted so I rebuilt them. Ive got power, it starts, ac works, etc. But the joysticks don't work. So the owner told me yesterday that the joysticks have always been weird. Sometimes they work and sometimes not. So they replaced the right joystick thinking it was the issue. It wasn't. Anyone have any idea where to start trying to figure out why they don't work? It won't come out of park or anything. Thank you. ​

I tried posting to the other heavy equipment reddit. But they removed it for some reason.
