Hello, and thank you for choosing Just Answer. My name is***** you are still in need of assistance, I will be happy to assist you.
Our problem very likely lies either in your ignition switch, or your seat safety switch. Keep in mind, that the two green wires, in the wiring connector, that attaches to your seat safety switch, have to have voltage when your seat is occupied, and your ignition switch is on. The voltage to your seat safety switch, is provide via the A1 terminal, on your ignition switch.
First, check to see if you are getting voltage in and out of your seat safety switch wiring connector, (Green Wires). If you are not getting voltage, check for a loose connection from A1 on your ignition switch. If you are getting voltage, jump these two wires together, then give your mower another try.
If your mower performs satisfactorily with your green wires jumped, then it is likely that your seat safety switch is at fault. Your seat safety switch is a Normally Open Switch. You can check it for continuity. With the button pressed in, you should have continuity.
Without voltage from your seat safety switch, your Operator Presence Relay will close your ground path, and shut your engine down, when you either release your brake, or attempt to engage your blades.
We can continue from here. Thanks!
