Hello Graham:

You can View a Breakdown/IPL of the Engine and Mower at this Site Addy, http://jdpc.deere.com/jdpc/servlet/com.deere.u90490.partscatalog.view.servlets.H... and Enter the Model Numbers (STX38) and Click Find. Then Select the Sectional File. Then Select the Section of the Mower you Wish to View Online. Select the Electrical File. Just to be Sure you have the Seat Safety Correctly Bypassed; **Check the Seat Safety Switch. PLEASE REMEMBER THAT THE INSTRUCTIONS FOR CHECKING THE SAFETY SWITCHES IS JUST THAT!!! FOR CHECKING ONLY. I NEVER Suggest a Mower be Operated with a Safety Device or Switch Disconnected or Bypassed. Now. On Some Model Mowers you can Simply Unplug the Safety Switch from the Harness. On Other Models you have to Place a Jumper Wire Between the Harness Terminals (on the 4 Post Switch Jumper from Same Color Wire to Same Color Wire). The Seat Safety is Showing No One is Seating in the Seat when the Clutch or Blades are Engaged.**  Make Sure you have a Good Connection if using a Jumper Wire. If the Seat Safety is Good, tehn Check for a Bad Wire. Sometime the Harness will get Rubbed and a Wire will Ground Against the Frame. This is a Rare Cause, but it Does Happen. If you Hit a Snag or this Does Not Correct the Problem,  I am Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Thanks.

Good Luck
