Could it be the reason it was on the curb was due to a bad coil ?

Hello Guys!
My current cooktop has a big crack. My wife literally found a pristine
ceramic cooktop on the street. I tried to install it - there were four
4-pole plugs which inserted properly into the oven part of the stove -
but when I turn it on, only the outer rings fire up. Compatibility
issues between stoves aside, I'm convinced I can make this work, if
only I can get some info on the wiring scheme. I am in Germany. The
oven/stove control is "Wamsler" The original cooktop is long gone, and
the recent one had it's own "surface" controls, so I can't reverse
engineer like I would like to. I simply can't find any wiring info for
either the stove/oven or the cooktop online. I'm hoping someone here
has expertise, and can give some helpful hints!
