Quoted from phil-lee:Spring overwound
Could be that. It should have 3-4 winds tops.
I had a similar looking thing though on my Klondike where the stepper was kind of twitching when activated and it was the coil, even though it had the correct ohm reading.
On steppers, from Clay's superb guide: http://www.pinrepair.com/em/index2.htm#steps
Quoted from Bkelley:So I disconnected one of the springs that the coil needs to fight to move ball to ball and it worked. Of course need the pull back for further operation... Seems like needs some marginal reduction in spring tension... Balancing act.
Is the other side nice and clean and contacts sitting correctly, and a bit of lube on the rivets? Something is off it you need to disconnect a spring. And did you check the coil with a multimeter?
