    That's my problem, I can not understand how I burned both at the same time for no apparent reason,
    if they burn so easily rotax engine would be the worst in the world, but we both know that's not the way that rotax built engines.

    That's why I came to the forum to see if anyone had been in the same situation

    I have never heard of both ignition modules going at the same time. Not being there is an issue, but I would look for something else.

    Hi Edgar

    I would definitely look for a broken wire or two around the modules. Depending on the age of the engine, some of the earlier modules (fitted with the 4 pin plug) had issues with the wire breaking down inside the coloured sleeve and so it looked perfectly OK, and could work fine, but the the wires could separate and cause the module to shut down. That would be my first point of call if it is an older engine.

    I'm with Mark. Check all wires first.

    i already check all the wires

    maybe we are dealing with a case that Rotax should study


    Thanks for your concern about my case
