I run through almost a case of Mooshead trying to figure this one out.

Mower does nothing when key is turned on to start. Without checking anything I put on a new start/selinoid. Stupid I know better....no change still dosen't do anything. I checked the following safety switches: both steering handles, hand brake, seat, pto (blade magnet works) both in line fuses & the on/off switch & battery. Everything checks out good.
With brake on, steering handles in correct position sitting on seat I have a closed circuit from the switch post S to motor wire harness plug.
I'd appreciate some tech help.

wouldn't hurt to post the mower model from the serial number tag. And I done gone my Go Go juice (Java) for the week and yet the crystal ball is still not working.

Yes I forgot to do that. It's a Z-Force 50 Zero-Turn Cub Cadet with a Kohler CV23 motor. Purchased 2006.

So you start by going to the Cub Cadet web site & downloading the wiring diagram which I believe will either be as a stand alone file or in the parts book,
The "cub Cadets and More " web site has the better information.
Next you check the battery terminals for 12 V
Then you check the hot wire on the solenoid for 12 V to the battery - and then to the engine , readings should be the same
Make sure you put the small red wire on top of the solenoid on the HOT terminal not the switched terminal easy mistake we have all done it .
Follow that thin wire and locate the fuse check bot sides of the fuse hosing for power ( should always be hot)
The fuse holders are notorious for going bad, corroding or breaking wires at the crimp .
Let us know how you go .

Mooshead? Isnt that for cows?

I know it may sound a bit stupid but haven't you tried raising this issue with chatgpt? many times he usually gives very accurate help

Yep i checked and I have power!

Ok I tried to follow the wiring diagram to create the following issues. One for start up where all switches are closed to complete a circuit from S on key switch to the solenoid. The other is for Ground out/no start where switches are closed to complete ground for the circuit from
G on key switch to the magneto. Now if I have the this right any of the safety switches in the wrong position will cause an issue.
Again I'm trying my best to figure this out.
Thanks for any input.

One note here in case you miss it the seat switch is a normally closed, meaning that when no one is on the seat it is a closed switch, open when someone is on he seat.

And if any of the switch are in the wrong position you will have a no start condition. They are two separate circuits so only switches the particular affect the ignition or starter depending which you are tracing.

it sounds like you have tried everything... Im not sure if it helps you but try to check ignition coil, no sparks, change it . If the safety switch working properly? check the spark plug for any signs of corrosion or fouling as well. uhh it probably be dumb to tell you to check the air filter right? double check the solenoid valve?

Thanks for all your help everyone. I studied the wiring diagrams some more and finally understand the two different circuits, one start up and one shut down. I fixed the start up and bypassed the pto shut down. This got her up and running for the time being. I'll finish up the year and replace the broken safety switches over winter.
Thanks Again!!
