There should be a coil chart in the manual that lists all the coil locations and part numbers for the coils. I remember seeing it in the volcano manual specifically.

I'd suspect the IC driving the transistor next. Although the transistor heating up like that sounds odd. Are you sure it isn't backwards?

Can you post a couple photos?

Quoted from MostlyHrmlss:

with some washers

Keep in mind, metal washers are electrically conductive.

Quoted from MostlyHrmlss:

I don't think either could feed it enough current to make it heat up as fast as it does. I could be wrong, though.

Too much current or voltage in the wrong direction can easily cook things.
