    Short of using a paper clip to complete the circuit, is there a better way to determine which switch is defective on a machine with multiple switches. I have a 44" Toro Z. When the handles are pushed out and the parking brake applied, the motor dies. Also it will not start with the brake applied and handles extended. Jumping the wires at the stater solenoid will start the engine so that eliminates the seat switch and everything works just fine. Just seems like a primitive way to isolate theproblem.

    Xpnd, If you know where each kill switch is, get your ohm meter & check the switch.

    There is a relay on that machine that controls the brake and motion control lever circuit. The contacts in the relay are silver, and if they corrode together it will keep killing the ignition circuit. your Toro Z is very similar to the Exmark Lazer Z as far as wiring goes. I think they use the same relay. Let me know what you find.
