hello, could anybody tell me how to figure out the primary
input pin(with approximate 1ohm coil inductance? how to find the polarity
for 2 input pins as well..)and the secondary high voltage and ground
pin for flyback transformer.. thanks

Hi!
I assume you mean flyback transformer as used in a TV or computer
monitor, not the kind of transformer used for (relatively) low-power
switching power supplies. If I'm wrong, please correct!
There
are several varieties of flyback transformer on the market. One kind
has a terminal common to the primary and secondary, the other does not.
Often, the output is a separate socket or lead, with high voltage
insulation - but not always.
To muddy the waters even further,
many modern flybacks are actually integrated power supplies - commonly
a voltage doubler or tripler is built in to the flyback itself.
So you need to be a bit more specific about what you need to know,
and where you're starting from!
Good Luck,
Fred
