Quoted from ryanwanger:Actually, it's not the coil sleeve. There is still a sleeve in the coil, but it won't budge, so I can't get it out.
My guess is it is a melted down coil/sleeve. They only melt in the middle sometimes, and it looks like someone shoved gum in it or something.
I would imagine you're transistor is gone too, the replacement coil will probly lock on, till the fuse blows again.
Not sure why that coil would lock on, or maybe the x-istor just failed.
