P90 Basic Mosfet Help

    Hi lads,

    I'm currently installing a basic mosfet into my P90, but for the life of me I can't figure out where to wire the trigger wire from the mosfet to the two stage P90 trigger assembly.

    The mosfet I'm using is a extreme fire SW SF which has three screw clamp terminals. One from the battery, one to the motor and one to the trigger switch.

    Every guide I've looked for deals with AB mofets which are wired a bit differently.

    Thanks :)

    You need to de-solder the RED wire coming from the motor which is currently connected to the switch at connection 2 and solder it at connection 1, you will now have three wires soldered together at connection 1

    You need to solder a new wire (this wire can be quiet small as it is only carrying 10-15ma) to connection 2 and attach to the MosFet at the 3rd connection from the left (the TRIG the one you circled in the photo)

    As this MosFet has a built in reseting fuse you could remove the existing fuse
