I am curious how you went about measuring the HV Side. How did you approach
this?

The transformer may just be 'burnt up' with severe short or something. Measure
the current on the LV and HV side for us to help.

The LV measurement can be done by placing the Multimeter in series with the
transformer, or by using a clamp amp.

The HV measurement can be taken by simply probing from one HV lead to the
other. Be careful your fuse is good in the multimeter, and do not slip when
measuring! 15kV can jump a solid 1/3 inch!
