Machine intermitenly fail to step from 1st ball to secon ball

[AMF82_70LUVER]

Tonight I ran into an issue that I have not encoutered before. Every so often Lane 5 after a person bowls table comes down and picks pins up then sets them back down the !st ball Light briefly flickers then stays on and then I have to manually step the machine to second ball. we are running 5 board converted to single board chassis. On a side not also Had several calls for a sweep on the same lane. Tep the machine back to first ball then press the cycle button and it will cycle just fine. What am I lookg for ?

Ah ha, 82/70, SS chassis with Omega Tek board. You are experiencing an issue with the table cams causing it not to flip or stay on a ball cycle. If there are no weak springs, loose wires, or bad micro switches, then it's probably just a simple adjustment.

With this chassis setup the ball cycle switch happens as the machine is finishing its cycle, TA2 and SA are responsible for switching balls and also TA1. The ball cycle switch actually happens while SA is lifted (sweep running up to home) and while TA2 is lifted- the switch occurs when TA2 presses in the switch before the table stops with TA1.

So basically this is what you should do....

You need to check the adjustment between TA1 and TA2. Standing a safe distance in front of the machine, run a cycle and watch these cam levers. As the table comes to the home position what you should see CLEARLY happen is the switch on TA2 get pressed in BEFORE TA1- if this is happening at the same time or too close together it will result in this kind of problem with ball cycle switching. If you conclude this needs to be adjusted, all you have to do it slightly adjust one or both of them until the above condition is met- you may have to slightly readjust the table cams but when you are done you need to clearly see it press TA2 in before TA1, as long as it is doing that it should be fine. What happens is that the O/T board can be really touchy about the cam switching and if these are close enough it will cause this issue with the board.

maybe ta2 double clicking?

Yup could be that too.

I could be smoking crack again, but can't the offspot switch and TA2 cause the machine to step between cycles? provided the offspot is hooked up/working.

If you still have the AUX board connected in the chassis, cut the wires at the mother board, take it off and deep six it.

This is a small (about 3" X 2" give or take) mounted on the inside of the chassis on the mask connector side of the chassis. It has a good sized silver rectangular relay on it and some other parts. If I find one, I'll post a pic of it. I've pitched all of them I come into contact with though... It's purpose is remember what cycle the machine was on. They are almost 50 years old at this point and can indeed cause this problem as well as other stuff already mentioned. Just get rid of it just in case.

BTW - I'm 52 years old - and this makes me uncomfortable to even say that...

You clearly don't work for an AMF if you can afford crack
