Hi, just wanted to add that my t1400 quit also and the short story is that I tracked it to a small white box on the wiring harness on the left side of the tractor as you sit in the seat. This box has two 5 amp fuses and both were blown. I replace them and Bingo! It started right away. In my case, it was no switch or starter or solenoid etc. frustrated by the time it took to find it but now if it happens again, I will look at the fuses first.
