Default Re: Testing a transformer for shorted turns

Nice simple idea.

I'm a little worried about what might happen if you used it on a low voltage secondary of a transformer. If there's enough voltage to light the neon (60 to 80V) then the voltage across the primary will be excessive.

Also don't connect it to a very low power transformer such as an intervalve one. The current from the battery may be sufficient to burn out a winding.
