The "real" way is with a high voltage probe for your DMM. Some of the probes have a switch on the side for the range. In practice, I've had pretty good luck with pulling an arc with a screwdriver. Assuming the transformer was sized right in the first place, it's either dead or it works.

You should publish a book with all your esoteric troubleshooting knowledge. There's your million dollar idea. :cool:

Or maybe write a column for a trade magazine. ;)
 
The screw driver works well. Ground tip FIRST then bring shaft to post (ignition transformers) and reverse procedure when test is complete. I only have 600v rated gloves but they do seem to give a false sense of security. I had a highvoltage probe for my first digital meter but never did trust it. Shorting as described or installing a spark plug onto the secondary worked best. I agree that they either work or don't.

With neon transformers I think it is the fall from ladder that usually does the damage, along with the ladder coming down on top of you.
