    Question:
    I need the complete wiring diagram for my Husqvarna RZ5424/96659301 mower. It is equipped with a Kohler Courage 24 engine. The mower product code is 289821 and the serial number is 021112C001839. I believe it is a 2012 production model.
    It will not start with the switches and levers in the correct positions. I have verified that all the micro switches are functioning correctly. The oil level is good and the battery is fully charged. The ignition switch's solenoid output at the terminal reads positive in the start position but not at the starter solenoid itself. I have verified the starter solenoid is good by running a positive lead to it which will successfully starts the engine. This is the only way the mower will operate. There is no obvious short or break in the wiring.
    I have the ignition schematic available to the consumer but need the full diagram to track down the source of my problem.

      Ok, feels like Deja-vu!  I have the same problem.  Of course, rather than diagnose the problem like you did I replaced the wiring harness and all of the sensors. 

      It started right up, ran great....then I turned it off and the problem has not been solved.  What is really maddening is that the when I turn the key to start the yellow prong goes hot at the switch but not at the connection to the solenoid.  I am thinking of just running a wire from the ignition switch to the solenoid and calling it a day.

      Hope you figured this out.
