Knocker not going off

[Peter munro]

On player one gottlieb top score knocker not going off for free game when high score is reached; on player 2 it does, what do I need to check thanks

If it’s working on player two I’d be checking the pcbs on the player one score reels

Do you have the schematic ? Find out what fires the Knocker coil through the second player circuit in the "player unit".


Is it working for the second / third high score ? ie - First is 10,000 points, second is 30,000 points - whatever it is set at.

High score knocker was working on player one but I adjusted score now knocker wont work it does work on player 2 on all 3 high scores; checked wires on score reels all seems ok, I don’t have diagram what enables the knocker to fire   Thanks Peter

Checked pcb on player 1 and found a wire had broken off re soldered now works as it should. Thanks for input Peter

Match number knocker not going off when last two digits match lighted number however it does go off at other times ie lighted number 50 and last two numbers say 20, what do I need to check to get the right alignment. Thanks Peter

Check the alignment and movement of the match unit (small stepper unit) also check the pcb on the 10s unit of each player

Cleaned 10s score reel not long ago and on inspection again wiper arm under reel not put back in right position, adjusted now matching. Thanks

Well done .  These games need tons of little tweaks to get them 100%

My solar city will match on player one but not player two, match relay seems fine and 10s relay pcb is good what else can I check. Thanks
