    I have a ytm200n as well.

    Don't know if you can help or not, but I figured I'd ask.

    My trike won't start. Looks like weak spark, but I still have no clue. Just trying to rule things out.

    Pickup coil ohms read to spec. Charge coil ohms are above spec. (should be 386ohm, is 460ohm). Charge coil generates about 60V AC while I'm cranking the engine over. Youtube claimed it should read 40V, but it wasn't a ytm200n so I don't know.

    Other check: Coil read in spec on the primary coil, but the secondary coil reads about 170K ohms, where it should read 5.9K ohms according to the manual.

    No big if you don't have time. I'm just wondering what a working machine reads before I spend a bunch of money on a coil and that isn't the issue. If possible could you measure your ignition coil. Spark plug wire to ground should read 5.9K ohms, according to the manual.
    Thanks,
    Jared
