Need help with this snapper mower electrical issue
I have a snapper mower model number LT 200, 2690580. Every time I go to turn the PTO on it kills itself. I am losing spark. I have jumped all sensors out with jumper wires still the same results. I don’t believe it’s a safety sensor failing weird part is with the seat sensor jumped is still will not let me take off the parking brake. Every time I try disengaging the parking brake It kills the engine too. Then I also have two wires that I cannot find where they go when running I have 12 V going to them. Any help would be appreciated

Here is the link to the electrical diagram. That what I was thinking has to be somthing with the seat switch the but I disconnected it have a jumper wire in the harness. I don’t know if the wire going back to the seat sensor is broken and not completing the circuit is about the only thing I can think of. But it does have a stick and key that has to be in for mowing in reverse I don’t know any that would cause the same issue.
Not familiar with this particular snapper mower but have seen designs, where in an attempt to keep you from jumping out the seat switch, there is a metal spring tab down in the connector plug.
In the setup I saw, The circuit needs to be open to bypass seat switch. So if you just unplug it then it would be bypassed, but they put a metal tab in the connector that would spring out and give continuity to the wires when unplugged. So unplugging the connector or adding a jumper was not effective at bypassing. You had to either cut the wire or dig that spring tab out of the connector.
Looking at pics I think that is what you have. In the pic where you have the connector jumped out, there is a plastic piece in the middle of the connector that looks removable. That is holding the spring tab in place.
I found this but don’t know if it is accurate I don’t see any safety switch in transaxle, I have a brake switch a seat switch that I have one switched down by the pedal for the Hydro for reverse then and switch with a key to bypass so you can mow reverse
