    Steve,

    Rest assured your code works fine.. I've just breadboarded the PIC and it works, yet in the PCB ot only wants to ramp up ????? - strange !!

    I would of thought that if there was something wrong with the PCB I made (like a short) then the thing would not work full stop ! The board uses a 5.1 zenner to provide the supply to the PIC, and the output simply from GPIO 0 drives the gate of the FET and the LED - why it ramps up and not down I don't know ?

    Thanks mate.. don't waste any more of your time... I've attached the schematic just in case someone might see whats the issue ?
