Re: [TCML] Simple MOT question?

The MOT produces AC, so their really is no positive or negative polarity . 
However, the HV side of the mot, you will see one terminal connected to the core of the MOT, this terminal should be your core ground and be your HV ground for safety reasons. otherwise you have a huge hunk of metal energized, which in turn could energize what ever its sitting on, bolted too, etc, depending on material obviously. . 
Of course, you can always run the mot floating, (ie, with the core not connected to ground) But be sure not to touch it which its running. 
I personally have run mine floating when I am just testing one or whatever, but if i actually install one in something for permanent use, I always ground that terminal 
Now if your gonna put a few of them together to get higher voltages, their is a systematic method for doing this which can be found online, and the mots location within the array decides if that terminal is grounded of floating. Oil is usually required when doing this. 

Their will be two more connections below the HV side, usually smashed between the 120V and HV, this is a filament coil, it will output a high current at 2 volts or something like that, I generally just cut these wires back so they don't get in the way. 

The 120V (thick magnet wire connections ) also don't have a polarity, connect either of these connections two your 120V hot and neutral as you see fit. switching them around will simply change the phase of your HV output. changing the phase is useful when your connecting multiple mots together in an array, as the phasing needs to be right or your outputs will cancel and such. 

Did I leave anything out?

Subject: [TCML] Simple MOT question? 

I pulled a MOT from a good working microwave and overlooked to mark 
the leads. Am I right in assuming the terminal on the right would have 
been connected to the negative and the terminal on the left positive, 
or is it the other way around?
