Stress tester repair help needed

I have listed this in all of the arcade related groups, but maybe a arcade repair person lurks in this group. Acquired a Stress Tester, and it doesn't work. Anyone have schematics, or any idea how to calibrate this unit (has several trimpots and a test mode) Thanks

That's much newer than the ones I've worked on -- which had model A ignition coils and a rheostat. I'd expect a multivibrator circuit driving a coil with something to variably limit the voltage.
