    Polaris Freedom Star/Stop button problem

    I Have 2002 polaris freedom and it have some problem with start/stop button.
    when engine is running and i try stop it with that button it won't stop.
    I think it start running starter but motor is allready running.
    only way to stop it is with kill switch.

    what would be the problem?

    Welcome to GH.

    I think there is a green button and a red button on that control.

    You are saying the RED button is not killing the engine?

    Welcome to the Hulk

    Click here for the Polaris Service Manuals.
    2002 Freedom wiring diagram is on page 349

    There are two stop buttons on your Freedom, I think. There is the button for the safety lanyard. Then there is a start/stop button. And a separate bilge button.

    When the engine is running, does the MFI show the engine RPM?

    Does the safety lanyard stop the engine when it is pulled out?

    The Start/Stop combination button;

    Remove and ground the spark plug wires. Now, when the engine is off, pressing the button cranks the engine, and releasing the button stops the cranking - correct?

    When the spark plug wires are connected, the engine starts when you press the button - correct?

    If you then press the button again, then engine does not stop - correct?

    If I understand this correctly, I would say you need to first check for a problem with the start/stop button.
    Unplug the connector at the starter solenoid, and use a multi-meter to check the voltage on the Yellow/Red pin. It should show zero volts, and then 12 volts when the button is pressed.

    Next check the Black/Yellow wire. Make sure it is properly connected through the terminal board to both the LR-505 module and the CDI ignition module.

    Also make sure the Yellow wire is properly connected to the LR-505 module, and to the magneto stator coil. This is important.

    The Black/Yellow wire is the actual kill signal to the CDI. When the lanyard is pulled out, the lanyard switch grounds Black/Yellow.

    When the engine is running, the LR-505 module senses RPM via the Yellow wire. When you press the start/stop switch, the voltage connects through the start solenoid coil to the LR-505.

    Since the Yellow RPM signal tells it the engine is currently running, it then grounds the Black/Yellow wire, instead of cranking the starter. This is what is supposed to be happening.

    What I suspect is happening is that the LR-505 module doesn't know the engine is running. So when you press the button again, it tries to start the engine, not stop it.

    If my understanding is correct, and the wiring to the LR-505 module is properly connected, then you may need to replace the LR-505 module. This module controls the stop function of the start/stop button.

    One other check. With the engine running, what is the battery voltage?
    It should be about 14.5 volts. If it is below 13.5 volts, then there is something wrong with the magneto stator coil, or the LR-505 module.

    There is a Start/stop button, lanyard button and that bilge button.
    lanyard stops engine but that start/stop button only runs starter again while engine is running.
    what is LR-505 module and where is it?
    is it inside the electric box?
    I have to check that Yellow wire if it tels to engine is running to module.

    sorry about my english, it's not my native language

    Your English is good enough to get this problem fixed

    Where are you located?
    Update your Profile here.

    The LR-505 module is inside the electrical box, if you have one. Some newer Polaris do not have an electrical box.

    I have attached photos of an LR-505. You can verify which one you have by the printing on one end, and the wire colors on the other end.

    Can you answer the other questions I listed previously?

    I checked my electric box, and there is ONLY CDI module...It don't have that LR-505 module at all?!?!?. I think someone have done some new wirings there because inside electric box only have that cdi...no fuses, no nothing else.
    and that yellow wire wasn't connected, it's only hanging around inside electric box.
    Strange....

    What are the last two digits of the HIN number plate on the rear deck? I want to confirm that it really is a 2002 Freedom model.

    What is the history of this machine?
    Did it used to work correctly?

    The 2002 Service manual shows both a LR-505 module and an LR-85 module in the wiring diagram. The 2002 Freedom Parts manual (pages 25-26) shows both the LR-505 and LR-85 lamp driver modules, plus the CDI in the electrical box.

    Do you have an MFI digital dash display, or just a fuel gauge and trouble light?

    Last two number is 02, so it's orginal 2002 model.
    I have only fuel gauge.
    i don't know what is the history of this but i start to wonder what the hell has happened,and why...
    it runs just fine except that engine stop thing, and i'm not sure does the oil and over heat warning lamp work, because those module are missing...

    Looking at the 2002 Freedom wiring diagram again, it looks like the LR-85 module may not be inside the electrical box.

    Have a look around the wiring harness for something that looks like another LR module.

    The LR-505 and CDI are supposed to be in the electrical box.

    Are you pressing the red button in the center of where the lanyard attaches?
