    Ski just stopped running, start button will not do anything.

    I sold the ski, but they brought it back saying it just stopped running.
    He said he started it, and rode it less than 200 feet, and it lost power.

    1999 Polaris X45 1200.

    Symptoms.
    Engine will turn by hand. Not blown, had plenty of blue oil smoke in my driveway upon a quick test start and rev.
    Battery is NEW and is at 12.7 volts
    Engine will crank with a screw driver across the solenoid.
    When you press the start button , nothing happens
    When you pull out really hard on the stop button and press start , nothing happens
    When you press bilge pump nothing happens - and it did before
    There is 12.7 volts on the other side of the circuit breaker
    Inside the handlebar button looks brand new.

    What would you look at next?

    Has anybody seen this ?

    Thanks for you help.

    Is the plastic battery cover in place on the battery? Look for signs that the battery may have shorted (momentarily) to the electrical box.

    OR perhaps the NEW battery was initially hooked up with reverse polarity, then reconnected with correct polarity.

    Measuring voltages inside the electrical box, put the black meter probe on the black terminals inside the box, not on the engine case or the battery negative.

    Thanks, there is no continuity between the black wires in the electrical box and the engine block or the battery.
    Engine block to battery is good.

    where is the electrical box connected to the block or battery ground, I cannot find the connections.
    Thanks for your help.

    ...
    That is a symptom of burned 'electrical box ground' wires, often caused by electrical box shorting the the battery posts.

    The entire electrical box 'ground' is connected to the engine via a single thin black wire in the cable bundle that goes to the magneto stator (Gen III red engine carburetor ignition system). That thin black wire typically gets toasted when the battery shorts to electrical box.

    Sometimes some of the thin black wires inside the electrical box are also burned out.

    Tip: Always disconnect battery cables before using ohm meter to check continuity. Battery voltages can confound the ohm measurements if battery is connected.

    Sound like a that is the issue,

    Is there a usual fix ?

    Thanks

    I have just added a new ground from the engine block to the junction in the electric box, and everything works.
    What does the purple wire to the coil shown in the stator connected to the black do?

    Was there a plastic cover over the battery?

    You can find the wiring diagram in the linked info. That includes stator wire color coding for Gen III stators.

    No cover over battery, , i will get one
    I find it hard to understand what it may have shorted to.

    But it runs now.

    Thanks for the guidance. I was focused on voltage not on the ground.

    The electrical box shell is metal. It is connected to engine ground via that thin black wire to the stator. The positive post on the battery has full battery voltage.

    If the positive battery post contacts the metal electrical box then you have a short circuit to ground. Until the thin black wire burns out.

    That is why the plastic battery cover is critical in all Polaris models where the electrical box is mount on top of the battery.

    Electricity always flows in a loop. ‘Ground’ is half of the circuit loop.
