    One side has 4 pins and the other side has 6 and below it it shows:

    O/P:5V/0.15A
    12V/3.6A

    I don't know what wires to check.. what should I be looking for as far as voltages going to it?

    Those are the specs for the power supply not the transformer.

    The transformer will likely have some form of 50KHz 160V/380V duty cycle modulated square wave on the primary and lower voltage square waves of the same freq on the secondary.

    Anyo one of the 4 legs on the primary side should give me like 160V and I should be looking for less on the secondary side right?I wonder if I'm not getting anything I think I found a shorted diode but not 100% sure yet.

    Everything really depends on what the hell you are trying to do with it, doesn´t it?
