take a 12V battery, connect the - to the hv output. then take a voltage meter and measure the Voltage between the + of battery and all the pin under the transformer. Only the ground of secondary gives you a significant reading. as for primary why dont you just wind your own on the exposed core of the flyback, of you can look for a pair of pin with a resistance of 1OhmHi all
I have a flyback from a tv set. I would like to make some expriments with it (HV, I know) but I dont know how can I define the legs of it (besides the red HV wire that is the HV output).
Dude, you think I don't know that. My mama taught me this in primary school. I'm telling the kid how to find the secondary ground cause its resistance is to high for a ordinary multimeter to handle.transformers dont work with a battery, that is direct current. you need alternating current. then only time current will be induced in the secondary winding is while the voltage is rising or falling in the primary causeing the magnetic lines of force to expand or collapse across the core.
Exactly, great minds think alike.electech. Chingyg was telling the poster how to determine the continuity on the pins of the transformer, not primary to secondary or anything like that. Just if one pin was directly connect to the other. Continuity testing on a multi meter will work just as well, but the secondary (HV) coil is usually a much higher resistance than the continuity of a meter will 'beep' to.
