Well see, the max current occurs probably a fraction of a second before the thing fails?
You feed power at variable voltages, with a load and see what it does. Then use maths to extrapolate the graph to the max (where it goes pop and catches fire...)

If its not tapped in many places to generate different voltages, you can form a pretty good idea from the size of the transformer, and the output voltage.

.  If the current rating is not on the xformer then you can get a ballpark figure by measuring the gauge of the wire and looking up the ampacity.
