Small Engines (Lawn Mowers, etc.): craftsman lt 1000 lawn tractor electrical problem, switch jumper, jumper wire


Question
finished mowing and cleaned tractor.  18 HP B&S engine OHV about 8 years old.  Started, but when the clutch is released, it dies.  Some type of electrical interlock device, I think.  Disconnected seat safety deadman switch and it still does it.  Transmission in neutral, blade disconnected.  There is an interlock where the blade must be disengaged to start.  Could it be the clutch interlock?

Answer
Hello Michael:

>>From your Description it Sounds like the Seat Safety or the Connection for the Seat Safety is Bad or the Safety Interlock Relay May Require Replacing.
>>The Following is the Instruction File for Checking 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. **Make Sure the Switch has a Good Connection. 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.**  
>>The Following is an Instruction File for the Safety Switch System. Any Input is Appreciated.
>>The Color Code of the Wires May be Different than those I Use as a Reference in the Instruction File.

>>**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 (Clutch/Brake) Jumper from Same Color Wire (Example: White to White) First and then Check for Fire, Now Include the Black to Black Wires if No Fire. Check the Clutch/Brake and the Blade/PTO Safety Switches First.  Then Check the Oil Guard Switch (if Applicable). Check the Seat Safety Last. Usually the Seat Safety is Not in the System for Starting the Engine. Just to Ensure Someone is in the Seat when Engaging the Transaxle and/or Blades. Use a Paper Clip or a Short Wire to Make a Jumper.**  
>>Use a Multi-meter and Check the Continuity of the Switch. The Meter should Show when the Contacts are Closed and Open. The Meter will Swing All the Way Over when the Switch Contacts are Closed and Swing Back to the Rest Point when the Switch Contacts are Open.
>>For Better Assistance, Send me the Model Numbers Off the Mower, Please. With these I can Locate the Proper Manual and Better Assist you. The Model Numbers are Usually Located Under the Seat (Ride On Mowers) on a Sticker or Tag on the Body. Examples: Honda Model Numbers; HR194 PXA, HRB215K2 SXA, ect. Example: Sears Model Numbers; 123.123456 .
>>A Model Number would Help me Assist you Better. Go to this Site Addy, http://www.searspartsdirect.com/partsdirect/index.action?sid=PSHx20080114x00001 and Use the Model Locator on this Page.
