The switch grounds through the ECM on the machine to allow starting.

Check the start relay and wiring as well and verify power to the starter solenoid small S terminal with the switch in the cranking position as ther should be. If so and not cranking over points to a failed starter. If no power then check the wiring, relays, fuses, and power in and out of the IGN switch and the safety switches.
