    Take the red/purple wire from the cdi, and connect it to the orange wire from the regulator.

    Welcome

    Starflight is correct, you need to apply the CDI power change (CDI Red/Purple wire moved to Orange terminal), which was covered in a Service Bulletin.

    Have a look here;
    Polaris Domestic (red) engine

    Put a voltmeter on the Red/Purple wire that feeds directly into the CDI module, without unplugging anything.

    What voltage do you see when the engine is not running (cold engine)?
    Should be zero volts, or close to zero.

    Start engine, what voltage do you see?

    Shut engine off. What voltage now?

    Do you have a bilge pump?
    Does it actually run when the engine is running?
    Does it stop running when the engine stops?

    Either the LR module as failed, or you did not change the CDI connection correctly, or you are measuring the wrong Red/Purple wire.

    the red/purple wire that gose from the cdi to the org wire is the one i did the voltage reading from.
