Yes, I do. I just came in from trying to put on the brake/clutch switch I bought today but what a pain. I finally just plugged it in and pushed in the plunger but to no avail. Won't crank. My son is coming home this weekend so I am going to start all over again with a helper to sit on the seat etc. while I test things.

I noticed you said the fuse looked ok, I would test it to make sure. I also like to check above fuse holder for voltage since I have seen them go bad.

Checked the fuse and it read 12.37 on both sides on the end of the fuse and I took it out and gave it the ohms check and it read 0. I was able to seat on the seat and reach over to the solenoid and the only thing that is live is the red cable coming from the battery to the right side of the solenoid. Even when I turn the key to start the only wire on the solenoid to show voltage is the feed from the battery. There is a small black relay box that is plugged in up near the ignition switch (number 81 on the wiring chart), would this have anything to do with a no crank situation? I did find the original owners manual which does have the nice wiring diagram that the gentleman form Australia mentioned and there is a trouble shooting section also that I will go through tonight.

print out the wiring diagram as big as you can then colour in the wires ( pinch the derwents of the kids/ grandkids ).
Starting at the solenoid control wire going back to the ignition switch.
It makes trouble shooting a lot easier.
JD do it with most of their manuals so suddenly they are not just a mass of confusing lines
Then go to the mower, paper in hand & follow the wiring back back testing ( poke the probes hard up the back of the plugs ) the wiring all the way to the solenoid.
Don't worry too much about the numbers just keep checking for voltage as back testing does not necessarily give you a good clean contact, particularly on a mower.
When you get down to the solenoid some have a resister in them ( to protect the starter motor ) and need 9V to trigger.
