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

ddstoys:
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.

Peter munro:
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

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