Remove spark plugs. Disconnect large RED electrical plug at engine. Crank engine by using jumper cable to energize starter solenoid (bat cable terminal to small 3/8" nut on solenoid). Do you now have spark?

Reconnect that electrical plug, then remove the black/yellow wire from the ignition switch. Now, with the key in the ON position, if you have spark with that wire disconnected but none with it connected, the ignition switch is shorted...... replace it.
