Small Engines (Lawn Mowers, etc.): KOhler CV15S 15.5 HP on a craftsman rider, switch jumper, jumper wire
QuestionEngine wont start. No spark. I disconnected the lead to the ignition module and i then had spark and can get the unit to run. Do i need a new ignition module? or is there a relay or bad wire from the lead to the ignition module bad? Can i run it without the lead connected? it runs so i am not sure. thanks
AnswerHello Mark:
If the Engine Runs with the Shut Off Wire Disconnected from the Coil/Magnetron/Armature/Ign Module, then the Coil/Magnetron/Amrature/Ign Module is Good. The Problem is Most Likely a Relay (Depends on Model) or a 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). Check the Clutch/Break and the Blade/PTO Safety Switches First. 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. If all teh Sawitches Check Good, then Check the Middle Relay in the Series Under the Seat. Change it with One of the Outer Relays. All 3 Relays are the Same, they Just Operate Different Sections of the Electrical System. You can Use the Model Numbers Under the Seat and Go to this Site Addy, http://www3.sears.com/ and Enter the Model Numbers in the Upper Left Search Box and Click Go. Then Visually Verify the Equipment and Click Continue. From this Page you can View Diagrams or Parts Lists for you Equipment. Hope this Helps. I am Here if You Require More Assistance. Let me Know What Happens, Please. Thanks.
Good Luck
