It's not likely that they are bad, but it is posssible. --- Quote from: spisi on August 30, 2022, 09:41:51 am ---What is attract mode exactly? Is it just when there are no credits and the game is going through various screens. Or is there a certain screen? --- End quote --- "Attract mode" is the time between gameplay sessions when the game shows a loop with the title screen, a short scoring/gameplay tutorial, and/or a sample of gameplay to attract the attention of passers-by and convince them to drop in some quarters and play. The manual didn't specify a specific screen or sequence during attract mode so the menu button press sequence should work if you start it when a game is not in progress. The menu button press sequence won't work if you release P1 Start (or the connection breaks) in the middle instead of at the end of the sequence. If you want to eliminate the switches and wiring harness as possible problems, you can insert straight pins into the P4 connector housing so they make contact with the sides of the wire pins then perform the button presses by shorting the straight pins with alligator clip jumpers. - P4 Pin 2 is ground. (black or green wire) - P4 Pin 5 is Service. (yellow wire) - P4 Pin 6 is P1 Start (white wire) - Connect one end of two alligator clip jumpers to the ground straight pin. (black or green wire) - During attract mode, connect the other end of the first jumper to the pin 6 P1 Start straight pin. (white wire) - Connect the other end of the second jumper to the pin 5 Service straight pin. (yellow wire) - Disconnect the second jumper from the pin 5 Service straight pin. (yellow wire) - Disconnect the first jumper from the pin 6 P1 Start straight pin. (white wire) - You should be in the game menu now. If that doesn't work, you might want to ask over at KLOV. Scott |

Glad to assist. :cheers: Did you figure out if the intermittent was in the wiring, P1 Start button or Service button? Is the PCB saving stats now? Scott |
| spisi:
Something must be wrong with the wiring or buttons. I didn't test that, I just did the straight pin thing and it worked no problem! Yessssss it's FINALLY saving stats! :applaud: |
