Ignition Switch Problem

[darkviper5]

hey, i have a mitsubishi MT372D and i got a kabuta tiller for it, but the hudralic lift quit lifting, so i did not know what to do, i let my brother fix it, well he fixed the lifting, apparently there was some screw broken, but made some damages on his own, he cut the ignition switch wiring, and hot wired it to start with out it, now i need to put the ignition switch back, and don't figure out what he did, i called him up and he says he can't remember, he did say he fried some kind of fuse near the clutch pedal, can anyone help me?

also after using the tiller for about two hours, i was so happy, then it quit lifting again, just ruined my day, what would be the problem? could it be that screw again? i want to work with that tractor, but i don't know anything about it.

if anyone could help me with the ignition switch problem, please do, i can post pictures of the switch and what my brother did to it. thanks in advance.
