when a MOT dies

I found an OLD 500 watt microwave, and I took the 2100VAC XMFR out of it and 
hooked it up to 120V, and tried to arc the + to -. I got a tiny 2" 
electrical flame and the transformer began to sing and turn into a super 
powerful electromagnet. It died soon after.

When MOT's are about to die, you can actually hear a change in pitch and you 
will notice the primary begin to vibrate radically, eventually you will pop 
the breaker. On a good standard MOT, the transformer has a STEADY 60Hz tone, 
and you should be able to pull a good 6" to 8" electrical flame between + 
and - with a 2kV tranny.

If you aren't getting these arcs or close to it, chuck the MOT out or rewire 
it!! The primary is most likely burned up.
