I like the idea that you started a new thread, but unless I want to take the time to go searching for your old threads. I don’t feel that this is the best use of my time. I don’t have much info to help you out. Things I don’t know.
1. What kind of Snapper are you talking about?
2. What are the units model and serial numbers?
3. What switches are you talking about?
4. Getting an engine to start and run is very different electrically than a units controls shutting down the engine.
5. Do you have any electrical troubleshooting experience and can you read electrical wiring diagrams if we can find them.
Sounds like you are throwing parts at this unit to see what sticks, but I try to help by figuring out causes before telling someone to spend money. Electrical troubleshooting is difficult enough if the unit is my shop, but trying to do it in a forum like this is nearly impossible if I don’t have a good picture of the problem. I’ll be glad to try to help you, but unless I have a better picture of what you have in front of you, there isn’t a whole lot I can do.

read your owners manual
To move you have to be in the seat & the brake must be off
So 2 switches need to be working for this to happen, the seat switch & the parking brake switch
So one or the other is not working or the wires between them is not sound

I’ve had plenty of experience with electrical troubleshooting, but you need to understand basic electricity before you try to tackle electrical troubleshooting. You posted pictures of wiring harnesses, not diagrams, they are mostly useless when troubleshooting. I’ve attached a wiring diagram, which techs use for this type of problem. Bert stated that there are two switches which may be the cause, so they will need to be tested. The seat switch-is NC when off the seat and the brake switch has two circuits, one is NC and the other is NO. On top of that the seat switch plug defaults to NC when disconnected. Hopefully you understand how these work or you’ll have a difficult time troubleshooting. There is also an electrical module where all these components hook into, which I’ve seen go bad.

I don't think there is way to test this,am l right or wrong

Rivets said:

Yes there is a way to test switches if you understand what NC (normally closed) and NO (normally open) means.
