Three techs here have both said most likely the seat switch or the seat switch circuit .
Got cut whatever wires some brain dead moron on face book said to do but it will still not run & if you cut the solenoid plunger off it will still not run
But if that is what makes you happy go ahead & do it , it is your mower.
If you want it fixed then listen to what you have been told here
If you wont more information then ask
From what you have posted to date it would appear you are well out of your comfort zone
If you don't understand then ask for a clarification
We have no idea of your machanical / electrical aptitude
You are just dots on a computer screen.
I would have posted a wiring diagram but since the take over craftsman searches are geo locked it USA & Canada only so I can not even pull up an IPL form down here any more .
And no one on this forum said anything about cutting anything
You were asked some questions & asked to do some tests
If you want help from the people on this forum then we expect you to do what was asked so we can get the information we need to properly diagnose your problems.
The other thing to remember is some get the forum as a complete thread while others just see it as a series of emails
So some of the answers will only reffer to the previous post and not the entire thread
This can get a little confusing if you are already out of your depth .
I went to the effort to explain to you & to one of the posters who had not thought through the actual thread why we think you have a safety circuit problem
And Slomo gave you instructions about how to verify this before Hugh sent us down the wrong path but he probably had not read your original post .
