Engine won't turn off when ign switch is turn to off

Sounds like an in-line fusable link. Check manual or car dealer and ask for location. If you find it, use a test light to check for voltage on both sides of link.

Is the security light on or flashing ?
The yellow wire goes from the key switch to the neutral safety switch, then to the starter. So bypassing the neutral safety would make the starter crank the engine, but would have nothing to do with the rest of the engine.

might be a burned spot on the starter contacts where the brushes power the motor.
tap the starter to see if problem goes away.
sometimes you can clean the contacts but that is a temporary fix.

You can bypass the fob IF you know the security code.

DO NOT sit on seat, lift bike off kick stand, or anything else that will activate the security mode!

Turn IGN to IGNITION.

Quickly (within 2 seconds) hold BOTH turn signal switches until confirmation signal (KEY icon flashes at fast rate, in odometer window, a flashing "-" will be followed by 4 more dashes = "----")

Enter 1st digit (a) in PIN by pressing LEFT turn signal switch (a) times (i.e., 5 times for the number 5)
The 1st "-" will become the 1st digit (i.e., "5")

Press RIGHT switch signal 1 TIME.
The 1st digit is stored and the dash will flash.

Enter 2nd digit (b), and repeat sequence until done.

After the 5th digit is entered, the KEY icon stops blinking, and the system is disarmed.

The system will stay off until the IGN switch is turned off.

If at any time during disarming sequence an error is made, wait 2 minutes before trying again.

ck the ign. switch

when it wont start does engine crank? do u hear a click, a clunk etc? this will help us provide troubleshooting guide

Hello pbck98:

>>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.
>>If Spark, then the Shut Off Switch or the Wire is Bad.
>>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 have a New Coil/Ign Coil and Still No Spark, then
>>Turn the Coil Over and Check for Spark. Ign Coils are Wound 1 Way for Clockwise Engine and the Oposite Way for Counter Clockwise Rotation Engines. I have Seen Ign Coil Boxed Wrong and Turning the Ign Coil Over will Correct the Problem.
>>The Coil is Gapped to .015in from the Flywheel.
For Better Assistance;
>>Send me the Make, Model and Type or Spec Numbers Off the Engine, Please. With these I can Locate the Proper Manual and Better Assist you.
Please, Do Not Hesitate, If I Missed Something or 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. Be Safe and Be Happy. Thanks.

Good Luck

Hello B-N-L:

>>I Suggest you Check the Ign Module First and then the Safety Switches if the Ign Module (Coil) is Good. Remember that the Ign Module May Check Good, but if the Safety Switches Check Good, then Most likely the Coil is in the Early Stages of Breaking Down and will Cause this Problem.
>>You can Check the Ign Module (Coil) by Using the Following Instruction File.
The Following is an Instruction File I Made for Checking and Repairing this Problem.
>>Run the Engine Until it Quits, then Remove the Spark Plug. Wrap a Wire Around the Threads and Attach the Other End of the Wire to the Engine Block Turn the Engine and See if the Plug Fires.
>>If No, then Disconnect the Shut Off Wire at the Control Bracket First, Check for Fire at the Plug. If Still No Fire at the Plug; Then Disconnect the Shut Off Wire at the Coil (usually requires removal of the blower housing) and Check for Fire at the Plug.
>>If No Fire at the Plug , then the Coil/Ign Module is Bad. The Coil/Ign Module to Flywheel Gap is .020in.
>>On Some Model JD Engines, there is a Igniter that Goes Bad and Not the Coil. The Igniter is the Same as an Ignition Module. If the Plug Fires at Anytime During these 2 Checks, then a Safety Switch or Wire May be the Problem. Yes the Engine will Turn Even with a Bad Seat Safety Safety Switch. Usually if the Engine will Not Turn with the Ign Switch; the Blade Safety or Neutral/Clutch Safety Switch is Usually the Cause of this.
>>The Starter Turns and the Engine Doesn't Fire is an Indication of a Bad Coil/Ign Module or a Faulty Blade Safety Switch.
>>The Blade and Clutch Safety Switches Prevent the Starter from Engaging so the Blades or the Mower Does Not Move when the Starter Turns the Engine.
>>The Seat Safety is Designed to Stop the Engine if the Blades are Engaged or the Clutch Safety is Not Engaged when you Leave the Seat.
>>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.
>>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 Volt/OHM/Continuity 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 the Safety Switches Check Good, then Check the Ign Module (Coil).
>>Thanks.

It Aslo May Need to Relearn--Turn Key on for 10 minutes then Off for 30 Secs then Turn it Back on for 10 Mins Do this 1 More time this should let the ECM RELEARN itself

if module is fine try replacing pick-up coil located in distributor.
