This is regarding the Castle in BSD. When a castle lock is qualified, I shoot the castle. The diverter comes down and the ball goes into the castle for Ball Lock 1. Opto 53 does not recognize the ball in the castle (almost every time, it does "see" it if the ball comes in really slow), the up post drops and the ball goes back into the shooter lane and fires back into play.
OK, so first I reseat all the connectors from the opto to the Opto Board under the playfield, Same issue.
Then I reflow solder to the connections on the 10 Opto Board. I also reflow solder on both sides of Opto 53. Same thing.
I "thickened" up the top of the Up Post to make sure the balls sitting in the Castle are dead in the middle of each of the 3 optos. Nada.
Switch Edge Test shows all optos closed as they should be. In switch edge test a slowly rolled ball checks out just fine on Opto 53. Anything faster than your Grandma triggers the first two optos then nothing for Opto 53 (Lock 1). It basically says that the last switch detected was Switch 54 (Lock 2).
I checked continuity from the optos to the 10 Opto Board with dmm, all good.
I replaced the pair of Optos (Transmitter/Reciever) for Opto 53. Same issue.
I replaced the 10 Opto Board with a brand new replacement board from Homepin thinking it was a bad LM339. No change.
My plan for tomorrow is a visual inspection of every inch of the wires between the opto and the board to see if maybe a partial break is causing these intermittent issues. As far as I can tell there are no other issues with any OTHER optos/switches.
Anyone have any ideas what else I should check/do?
