    Seadoo 717 Stator Testing

    1999 GTI 717 Seadoo.
    1) Testing Yellow and Yellow/Black wires on stator, get .6 ohms (spec is 0.05-0.6).
    2) Black and Black/Red get 58 ohms (spec 40-76 ohms)
    3) No power to White coil wire. Have continuity from MPEM to White coil wire while cranking.
    Disconnected Black/Red wire (limitor). No power to White coil wire at crank.
    4) Voltage between Yellow/Yellow/Black wire is 2 VDC
    5) Voltage between Black and Black/Red is 3VAC.Spec on Yellow and Yellow/Black is 12 to 25 VDC running at 3500 RPM
    Spec on Black and Black/Red is 45 to 75 VAC at 3500

    Of course I don't neither specificatons since I am getting no spark to the coil.
    Any suggestions on what it is for to try next?

    What is your battery voltage while cranking?

    About 10.8 volts while cranking. Battery fully charged a 13.1 volts.

    Let me check my notes tomorrow on those cranking voltages.

    I tried a new MPEM. Didn't work. I ohm spec'd out the Generating and Charging coils at static. Both were well within specs.

    Can a stator that is showing fine at static be still bad?

    Stator ohms can be well within spec but have low output voltage. Give me a minute.......

    Ok, make sure your meter is reading properly.....stick the leads in an outlet and check for 120vac.

    My notes say yellow to yellow 6vac while cranking.
    Blk to blk/red 20vac while cranking.

    My Black to Black/Red is 3 VAC. Yellow to Yellow/Black is 2 VAC. Both at cranking.Looks like Mr. Stator is toast.

    That would be my guess......I'd sure try a different one.

    New stator didn't work. Black to Black/Red is 2.5 VAC. Yellow to Yellow/Black is 3.5 VAC. Both at cranking.I purchase this stator from JetUnit. Wondering if phases are reversed. I had this same problem with JetUnit on a 2000 Polaris Genesis FFI. Had to switch pins to get the right 20VAC.http://greenhulk.net/forums/showthre...=294026&page=4
