| Oct 27, 2017 at 0:16 | comment | added | Barry | This answer is good but how will the OP, given his level of knowledge and equipment, get a 5 volt, 60 Hz source? | |
| Oct 26, 2017 at 22:58 | comment | added | HXGamer | @mguima Thanks! I added my results to the main question. | |
| Oct 26, 2017 at 19:14 | comment | added | Marcovecchio | @mguima, I agree! But anyway, the AC generator is not necessary for wire identification, which is what the OP asked in the first place. I added this last test using AC just for completeness. However, he will need at least a cheap meter, otherwise he will have to guess! | |
| Oct 26, 2017 at 19:06 | comment | added | mguima | @Marcovecchio, I voted +1 for this answer that talks about using three resistors and also a 5V 60Hz sinusoidal generator, because it is technically perfect, but, for a perfect world. I fear that this answer will not help an OP who is trying to test a transformer using a 9v battery and watching the sparks! He probably doesn't have a multimeter neither a continuity tester, and maybe don't know what those equipments are. Sinusoidal generator is too much for him! | |
