AnswerHello Gerald:
>>You can View a Breakdown of the Engine at this Site Addy; http://www.kohlerplus.com/login.asp (IE5 or Higher Required) and Select Enter as Guest. Now Select the Thumbnail of the Engine Catalog you Wish to View.
>>The Following is a Basic Instruction File I Made for Checking the Coil/Ign Coil/Magnetron/Armature on Small Engines. Any Input is Appreciated.
>>**To Check the Ign Coil; Remove the Spark Plug/s.
>>With a Good Plug, Wrap a Wire Around the Threads of the Plug and Attach the Other End of the Wire to the Engine Block.
>>Remove the Blower Housing (metal engine cover). The Wire that is Connected to the Coil/Ign Module from the Shut Off Switch needs to be Removed (unplugged) from the Coil/Ign Module.
>>Now Check for Spark at the Plug. **You can Replace the Blower Housing to Turn the Engine with the Recoil Starter.
>>If Spark, then the Shut Off Switch or the Wire is Bad or 1 of the Safety Switches is Bad (or has a Bad Connection) and Requires Replacing.
>>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 (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.
>>If Still No Spark, then the Coil/Ign Module is Bad. If there are Safety Switches on this Unit and the Coil is Good; you Need to Check the Safety Switches for Being Bad and Check the Oil Guard Switch also.**
>>If you Hit a Snag or this Does Not Correct the Problem, I Hope to be Here if You Require More Assistance. Hope this Helps. Let me Know What Happens, Please. May the All Mighty Bless You and Yours. Be Safe and Happy. Thanks.
Good Luck
