Hi Neal you can do the reverse amp check ... short the hi V
outputs and read the amps the 120V source draws and work the amps
backwards from 15KV if you get a really oddball reading ( not 30 or
60mA ) then try the numbers with the secondary side at 12KV and repeat
the numbers see how that turns out ...
