I Recently got a KILLER DEAL on the 38" Rider Mower listed in the title. Runs GREAT but won't crank without jumping the Starter Solenoid! NEW Battery, Positive Cable, Starter Solenoid, 4 Position Starter Switch. I suspect it's a faulty Seat Switch, Mower Disengage Switch, or Park Brake Switch. My PROBLEM is I can't find MANUALS or a WEB SITE that recognizes my MODEL NUMBER (including the MURRAY site) NEED some HELP HERE!! Am I on the right track here TROUBLESHOOTING? WHERE can I get MANUALS? The Mower was assembled in Lawrenceburg, TN. Thank you

It is most likely one of the safety switches you have discussed as they interrupt the start sequence via the solenoid. You have to check each switch independently for change of continuity relative to the engaged and disengaged switch position to determine which switch may be at fault. If you find that all are working then check for a shorted lead wire from any of the switches next by checking each for continuity. Good luck
