Fully restored Strange World chime unit is acting up on me. The very first time one of the tens point sling gets hit and fires, the chime unit( smallest bar) rings normally. From then on, the metal plunger that strikes the bar is held up into the coil until I power off the game. With the game off, the plunger drops out and then easily goes in and out of the coil. Is there some sort of magnetization going on? Any help is appreciated. Thanks!
