    Polaris backfires, cranks but won't turn over

    I have an 01 Scrambler 500 4x4. Been running fine. I started it and it died about a block down the road. Did the same thing again. Now it wont start at all cranks but wont turn over seems likes it backfiring through carb. Also, I did some welding on the back rack would that have an effect on the CDI or anything. Thanks

    probaly messed up somthing electical stator or cdi. are you getting spark all the time? It could also be anything from bad or coroded wire in ignition, kill switch, plug wire or faulty plug. but it definitly sound electrical.

    yes, Im getting spark. I got it to run for about a minute then it made an odd noise and died again. Is there anyway to test the cdi box? thanks

    its definitly a stator or cdi problem. talk to the dealer and c iftheymay have a spare cdi of a wrecked pred outlaw 500 or scrambeler, i belive they all are the same.

    Its rare for a cdi to just up and quit. i would pull your mag cover off and take a look inside. i had lots of problem with my old sportsman due to water in there also make sure the magnetic pick up on the outside of the flywheel isnt covered with metal filing from the starter bedix. and you may want pick up a climer manual they have all the tests in there exept for the cdi cause you cant really test it.

    Check the flywheel key while you are in the mag cover.

    The stator is a common problem with the 500 engine. If you find the stator to be the problem, google ricky stator before you have a heart attack when you find out the OEM price.
