    Wattage is based on the load, not the generator. If you open the output of the stator, there's no load and no wattage. Shouldn't be a problem. (That's basically what the headlight trick does - opens one phase of the stator.)

    The one thing that opening the output will do is cause a very high voltage at the stator output. The rectifiers have to be rated to take the high voltage AND source the entire current used by the bike. (Anybody know what that is?) Also, the regulator circuit itself must be able to handle the high voltage coming off the stator.

    Switching supplies are very efficient. In fact, it wouldn't surprise me if a stator lived longer with a switcher since it doesn't need to generate as much current when the electrical system is lightly loaded.

      The voltage spikes are/can/will be filtered by a moderately sized capacitor...
