Small Engines (Lawn Mowers, etc.): CRAFTSMAN TRACTOR SEAT SWITCH, craftsman model, jumper wire

Question
Craftsman model 917.274040.  I thought seat switch had short in it and I tried to bypass it.  I do not understand the wiring schematic on removable and non-removable connections.  I got upset and cut the switch off the wires and put the wires together to complete the circuit but it still wont run when I let off clutch. Do I need to separate the wires or disconnect something else? Luckily it wont be needed till spring. I am a lifelong do-it-yourselfer and still learning that frustration does not pay, it costs. Any advice you can offer will be greatly appreciated. Thank you.

Answer
Hello Angela:

From your Description it Sounds like the Seat or Brake/Clutch Safety Switch is Bad. Lets Do some Diagnostics. 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. **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 (Clutch/Brake) Jumper from Same Color Wire 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 (the PTO Switch is the Safety for the PTO Operated Units). 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.**  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. Have a Happy Holiday Season and May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.

Good Luck
