Worth asking, did the tech mean the high voltage transformer that creates
the electric arc? Or the low voltage transformer that does the controls?
The high voltage transformer, I'd not want to try and read the output of

Do you have a voltmeter? If so, just monitor the output voltage from
the transformer when things are normal, leave it hooked up, and at the
next failure check the voltmeter to see if it is still putting out the
same voltage. This is basic, if you don't understand then find a
helpful handy neighbor.
