    Re: Bad transformer

    I would first consider the controller IC. How about a picture of the board so we can locate the components on it.

    No I dont have a ring tester. I was looking for a board but no luck.Mabey I can find a generic one somewhere.

    Re: Bad transformer

    The only way to be sure is to test it with a ring tester, but I doubt you have one. Another possibility is the controller IC is damaged and the output is stuck permanently on, which will blow the fuse.

    I checked all fets and the gates work on all of them.Pain in the butt with a 9v battery.
    This set had a lightning surge and the power strip even burned out.So much for bargen power strips.

    The transformer is just a part of the supply. Something in line with it is more than likely failed; probably a shorted MOSFET, which drives the transformer.

    Re: Bad transformer

    I have no reading at all and the transformer is off the board.
    F1 only blows with transformer on the board.

    Re: Bad transformer

    What resistance do you get? Primary side rarely fail, its DC resistance will typical be less than 1 Ohm. I doubt that you have bad transformer.
    Did you chekc the rectifers, MOSFET'S, etc?
    Any picutres of the boards?
