    Polaris stator voltage

    2003 msx 140

    Just found out that the voltage regulator on this ski is integrated into the EMM.

    ski just had a new stator and flywheel installed last year, dealer that installed it told me it is throwing a code telling him stator is bad, is there a way to check voltage coming out of stator?

    I'm still holding off on sending the EMM in to DFI because my local dealer just downloaded my program and uploaded to another ski with a new EMM that he received with no program installed from polaris. Once program was uploaded on other ski it now runs fine.

    What the dealer did was transfer the fuel injector 'compensation maps' from your old EMM to the replacement EMM.

    If YOUR engine runs properly with the new EMM and not with the old EMM then the old EMM has a problem.

    Note: Always specify which model and year watercraft you are asking about

    Just had time to check resistance on stator pins.
    Pins 2&11 should show .1-.3 oms resistance, they were showing 34-36.
    Only thing is, this stator is only about a year old.
    Wish I knew what caused this stator to fail so soon

    34 ohms or .34 ohms?

    This does not make sense. There is no point in transferring your injector maps into another new EMM unless that new EMM is then installed onto your engine.

    Did your engine run with this new EMM?

    I was kind of hoping since he called to borrow my ski for this that he would've swapped the EMM out to troubleshoot this problem for me. Didn't happen. He did hook mine up to do a diagnostic and came to the conclusion the stator was bad and air temp sensor is bad
