    For mains T/F I just conect to the power with secondary disconected & check current draw, if excessive will have shorted turns & over heat. SMPS T/Fs i use a home built tester that suplys a HF sine wave to T/F, & meter. If there is shorted turns the meter needle will drop. This little unit has served me well for nearly 30Yrs, checking SMPS & TV flyback T/Fs.
