I have a Z724 zero turn mower.

I replaced the starting coil the other day and it started right up. I cut for about half an hour and when I got to the end of the driveway I stopped and did not have the blades engaged and when I got up the mower died. I have not been able to get it started since, The relays click and engine light is on but the starter does not engage. So I wanted to test it and bypass the entire saftey switches to see if that was the problem. If it is then figure out how to which one it is by tracking down the wiring,

I just do not know which wires will bypass them all or if its a relay. so if anyone can tell me I would appreciate it.
