I bought a M6950 a few weeks back from some cowboy farmers that said there was a "bad ground or wire" some where. Turns out they removed the inline burn fuse to the starter and also fried the whole wiring harness. I am pretty mechanical and work around heavy demolition equipment everyday so I figure no problem not realizing how bad it was. There are "NO" harness's in the US and I found one in a salvage machine in Canada. New OEM at over $600.00 and a few weeks out. I wanna undo everything they have done

The wires they have cut and spliced are the white power wire that is cut and crimped together with one wire going to distribution bar and the other to the starter replay. The other is the black wire with a white line coming from the key to the starter relay also. That is cut and spliced into a solid black wire.

Can someone reassure me how it's suppose to go and even provide a picture? I have a service manual can get my way through it.

There is no way these turkeys didn't know that they screwed something up and were not honest. I figured it was a safety switch or the fuse but not the harness being fried.

Thanks for any help

If you have the service manual then there should be a wiring schematic, it would be a lot better than anyone trying to explain where every wire should go. ;)

Caution: That model of tractor is probably going to have electronics in it and if they are not already damaged they could get that way if you feed power to them in the wrong place.
also the safety switches will be low voltage and will feed the OPC computer not the starter solenoid like older models.

This may help. See attached.

My suggestion is to blow the image up, print it as partial pages at the same scale and tape it together as a large sheet.

I lost access to my Acrobat Pro or I would do more for you.
