Many MOT's are different so you sort of have to test for what you have....

Just a couple f things needing pointing out...
1. MAKE SURE TO GROUND THE CORE (that bolt where the secondary attaches is a good place to do this). If you do not then the core will have 2.2kv on it, as well as anything melt attached to it. Also because the primary winding was not designed to handle the high voltage you can get arking to it, which can in turn connect the high current from the mains in in series with the hv out, providing a very deadly situation.
2. Make sure to use some type of ballast. If you do not use a ballast it will overheat and you won't have a mot anymore.
Also, there probably will only be 1 hvout, so don't spend too much time looking for the second one.

Be safe and have fun :)

Very carefully.

Remember that a MOT is a LETHAL device. It is not like an NST. If you get shocked by a NST, you'll likely live to see the next day. One mistake with a MOT, and it will likely be your last. They are not current limited and should you get shocked by one, thats 2100VAC with practically nothing to current limit it. Almost like a mini pole transformer.

Seems like everyone here is providing info to your response, but no one has asked the obvious . . .

What will you be using it for???

I got shocked by my 4 stack once. It was about the most awful experience of my life. Keep that in mind when your using these things. Luckily, I must have hit the switch with my hand and stopped it. Burned a nice DEEP hole in my left thumb and a long line down my right palm. It hurt for weeks. Not to burst any bubbles, just be careful. I'm really lucky I'm still around.

Omicron,

Please provide a little more information when you post, this way the rest of the group here has a better idea of what you are attempting to do, and what problems you may be having. Most of members here will go out of their way to address your concerns, and answer your questions, however without a clear idea of what you are trying to do, its very difficult for us to help you.

Remember, if you expect members of this group to take the time to help you, then you should take the time to clearly state your intentions and inquiries with as much information as possible instead of simply posting, "I'MMMMMMMMMMM BACK - I tried it and nothing"

Thanks
Dan
