Thanks for the reply. Both of those switches in the lock work fine as stated in my initial post. Rolling a ball into the lock and they both register.
Hi Angus. Please re-read my post. There is only one switch in question, #62. This is the one right behind the newton ball. The switch is most likely working. The problem is that the switch has to sense that a ball is on it when the sarc is in it's flat position (which it probably does), but it also has to sense that a ball is present when the sarc is lifted in the back to accept a ball from the ramp shot. The position of the sarc changes where the ball hits the switch tip. The switches on the LE's are an early design where the tip almost comes to a point at its highest point This leads to the problem where it's only being triggered when the sarc is flat. The arm on the newer switch design has a longer, flatter top which allows it to be more easily triggered when the sarc is in different positions.
I would recommend that you try your switch tests again. I'm pretty sure that you are going to find the switch is not being triggered (or is intermediately being triggered) by the ball when the back of the sarc is lifted up.
Edit: Angus, my apologies. I mentioned switch #62 a couple times and I was confusing that with switch #39 or #40 (whichever is the one right behind the newton ball). #62 is the one on the sarc mechanism disc that senses the back of the sarc is down and under the playfield. If you are getting confirmation that all 4 of the switches on that disc are operating correctly, not sure why you would get an error regarding #62. However, I'm not sure that the behavior of not locking the ball during play has anything to do with switch #62. #62 shouldn't be triggered until a ball is unloaded from the sarc. I had the same issue as you. When the ball dropped into the sarc, the back of it would immediately lower and put it under the playfield to be ejected out from the ramp. Would never lock the ball. The switch right behind the newton ball worked fine, but it would not sense a ball when the sarc was in its loading position from the ramp. I replaced the switch with the new design and never an issue since. There were no error for the switch because it would get triggered when sarc was flat.
