I tried:

1. cleaning the jones plug next to the indicator disk.

2. manually manipulating the gear/ latch mechanism in the indicator disk

3. filing the switches on the tracking control relay.

One of these actions (im guessing 2) caused the 100s scoring to get out of sync. The top rollovers register 300 when the ball enters play instead of 500.

Also, spinning the hands on the clock activates the state tracking control relay, but is no longer activating the score motor.

I suspect manual manipulation of the indicator disk was a mistake.

Internal documentation (literally)

Relays do not seem to always work in proper order on clock changes after the first ball relay has been triggered. They don’t move. Here is slow motion video of proper movement

No particular rollover seems to be involved as far as I can tell

It would appear 5 of the 10 rollovers are associated with the problem. I marked them with blue tape

The clock wheel is associated with relays on rollover switches. Only once a rollover switch relay has been triggered does the clock result in infinite score wheel rotation

The video shows it happening when I hit many rollover switches but perhaps just one is guilty

I did not have an issue playing Stock Car today either, all 5 balls went fine. We should tilt the machine to test Josh’s theory.

The same issue that Matt had yesterday has resurfaced. A guest stated that that they drained with 4 balls left in their game and the ball wouldn’t return to the plunge lane. The game was making the ticking noise again and after a few nudges it still didn’t return the ball to the plunge lane. I proceeded to press the start button and it reset the game. Is it possible that tilting on Stock Car ends your whole game rather than just the ball?
