Pusher, actually every coil, be it a stator, an exciter coil, a spark coil or whatever, uses enameled wire when wound. So they attach the colored stranded wires at some point near the actual windings. So if all you need are new exiting wires because of the insulation cracking, you could easily go into the coating and get to the solders points for those colored wires and solder new ones on. Then mix up some epoxy and apply over the coatings and you should be good to go again. NO it isn't a piece of cake, but it isn't that hard to do either. And for a little effort, you could save yourself lots of money. JMHO
If you think you will have to cut up the sealed coating too much on your stator, you can make a mold from the original stator before even cutting into it so that when you finish soldering new colored strand wire outlines, you could mix up some epoxy and set the stator into it to seal it all up again. Just an idea.
