    I have a kwa Sr12, and I am using a 9.6 v battery, have a infected armory active breaking mosfet installed, and for starters, semi does not work, and at the moment, when I plug in the battery or touch the deans connectors together, it starts firing... I think either the mosfet is bad, or the contacts are stuck, any other ideas ?

    Those are the two things that come to mind for me too.

    For the semi auto, check your selector plate and cut off lever.

    your mosfet is infected... in the past, they had a very high failure rate. if you run your battery dead, it will fry the mosfet. losing semi-auto can be caused by a number of problems, worn down cutoff lever, worn down selector plate, damaged trigger shuttle or broken trigger shuttle stop post.
