I have replaced the solenoid,the switch.checked the wires none burned are
Broken.that I can see. Charged the battery.disconected the starter hot wire
It still blows the fuse. When you turn the key. Disconected the wires under the
Flywheel it still won't start are even click just blows the fuse

Hi,
You have a short to ground somewhere in the fuse circuit. Provide the model number and I can probably, but not always, get you the wiring schematic and maybe give a clue.
Peace,

Hi Crigby
Yes your right that's what the problem is. And was, I took the top off the mower giving me access to the harness and I found many wires burned and melted together.And several large worn (no insulation left) Bare wires were they were mashed and rubbing on the frame .I could not tape up all the bad wires.So I replaced the whole harness.And problem solved THANKS For your response
