Hi Pinball Fans,

My 1980's BK was working perfectly, went to play it yesterday, and noticed a strange issue. It's intermittent, but I am able to reproduce it every time for a certain scenario.

When there are 2 out of play balls in the upper playfield lock lane, the plunger lane kickout solenoid goes off continuously. When zero or 1 ballis in the upper lock, the game functions normally.

I have looked for any obvious leaf contact that are stuck closed, or not making contact, and they appear to be correct.

Which switch is likely the culprit for this error to occur? How do I check it, and or fix it?

Any thoughts on this appreciated!

Ball trough switch may be stuck on. The one I circled in the attached pic.
