Nice to hear you got your opto prob fixed. I picked up a Maverick recently and it has not been working since day one. The ball will lock and register but then a bit later (randomly) the ball will release causing a 2 ball multiball (not correct).

I reflowed boat opto 1 on (receiver and transmitter). when putting it back together it did not work. it turns out that is was not aligned. so after much tweaking i got them aligned.

I thoroughly tested the boat optos (with balls). everything worked in switch test. fire up a game and shortly after locking ball one, during single ball play the boat released the ball again.

Maybe i still need to tweak the alignment of boat opto 1. Is there something else i should be looking at?

Well it turns out i was working on the boat optos when i should have been working on the boat entrance opto. turns out that the optos have been replaced with a read switch that does not work well. it seems to register randomly making my machine think that a ball has entered so it releases a 2nd ball into play.

I would like to put optos back in there. does anyone know where i can get a set that would work for this? is there a plug and play option?

I guess i should start with finding the part number and see anyone has them.

So I wonder why optos were never a good solution in the first place? Why did they not work well for that application? (boat entrance)

I wonder if I swapped back to optos (if i can find them) if i will just encounter the same original problems?

My reed switch is essentially having the same problems that I imagine the optos were having.

Maybe there is some adjustment I can do to my reed switch that will solve the issue as you suggested.

Anyone have any experience with reed switch adjustments and any recommendations?

Good info! Maybe I will revert to optos if I can find the boards!
