It's been awhile now but my island acts up and seems to hang up causing a misalignment of the entrance from the ramp.
I have video here: https://photos.app.goo.gl/KrDVGYtVQioeLwoo6
If the island goes around a full cycle, I believe that it does re-sync at some point (don't recall at the moment). Also, I have removed the island and even raised it up a bit (on the rod) before tightening the set screw in hopes that it wasn't maybe pressing down too hard on the post which is coil controlled (pops up into the holes in the island track.
The one opto on the playfield under the island is brand new.
Let me know what to try, please share any pics that you might have of underneath your island etc...
Thanks.
