Welcome to JUST ANSWER small engines, let me try to help you !! I don't know it all, but maybe together we can get you a satisfactory answer!
TT45A, you can't spin engine with the keyswitch? Do the glow plugs wok from the key? Any indication there is voltage to the key? All fuses check good with a meter?
I can't address the charges, I only work from home as a contractor. You will have to contact site ofr any billing or charges. If keyswitch will not engage the starter, check the seat switch and the neutral switch, but usually it is the pto switch. Either bent or harness damaged to it. Located at the end of the pto lever under the fender. Best to not try to bypass the safety switches.
Don't over look the pto, it can just be moved, where it is not in neutral, and will keep tractor from starting, You don't have to have used it!
I see question is still open, did you find problem?
