Ok AVB, if it has a magnetron coil then all Nev needs to do is disconnect the wire wherever he can, then if he still has no spark then the coil is the problem.
Now is of course that is based on the model and type numbers given. If it is like it is here people swap these shrouds without even thinking about the important of the numbers. But I am fairly certain with the wire being a thin black wire it is the magneto kill wire.
