Power Transformer Testing - how to

[anti-doom]

I have some power transformers and output transformers. How do I check or test them to know which one is good and which one is bad? Any recommendation would be appreciated. Thanks?

Ues a ohm meter, but you will have to have the schematics of the transformer to tell you what the color coded wires are for. For example the primary output taps , test with a ohm meter, it should give you a reading, then test secondary output taps or wires and that should also give you a reading. Then test primary and a secondary wire, there should not be any reading on your ohm meter.
Youtube has a few good videos on testing transformers.

Uhm, plug it in and check for appropriate voltages?
