Quoted from schudel5:
I've never run into a coil that just 'weakens'. I have run into coils that just stop working (broken winding...I had one just happen again last night) or blows a fuse (shorted winding). If it seems like the coil is sluggish or doesn't have enough ooomph, it's always been a mechanical issue with the linkages or coil sleeve, tarnished connector or dirty switch contact to the coil.
Yes there have been situations where the coil has overheated, at some point in it's life from being shorted on, and the inside diameter has decreased. This is still a result of something happening to the coil indirectly that caused the coil to become damaged.

Yea, stop holding the flipper up people! We know who you are!
