I'm going through an IJ and trying to figure out if I have some missing pieces related to the ball diverter in the upper right ramp.

I looked at the a-16301 diagram on 2-33 of the manual, and I do have that coil that the diverter arm connects to.
What seems funky is that the arm just seems floppy-floppy (technical term) with no resistance in either direction. It also didn't seem to "return" to a certain position (like I would expect a flipper to do). In other words, I can flip it back and forth, and it will stay wherever I put it.

Finally, the bottom of the guide seems like it is grinding on the bottom of the ramp. It seem a like there should be some kind of bushing between the ramp and the arm?

I'm not sure how this is supposed to normally operate, but this doesn't seem like it is as it is supposed to be.
