I'm sure you figured out that you have/had something wired wrong. You evidently had a hot wire going straight to ground. After you tried to hook up the key switch and it overheated what did you do then?
Did you swap the wires around and now you think it is hooked up correctly?
You will need to follow out each wire and check it for burnt places. Do you have a wiring diagram for the Gravley and also for the motor off of the John Deere? You would need to compare the wiring diagrams, and pay particular attention to the colors. Red will not necessarily go to red.
You did not give us what brand the blown motor is.
You have a difficult job in front of you. First, you must repair any damage that was done.
You could do some searches on this board for swapping motors, or a ignition switch and read those threads.
I think there are also some YouTube videos that explain about swapping motors. I watched a good one a month or two back.
Would it be possible to take the ignition switch off of the John Deere mower if it is needed? If it still has the wires connected to it that could be some help and understanding the wiring diagram.
