My Flip-A-Card was working great but usually on powering on the game and 1st startup, the thousands reel would stop at 7. Additional presses of the start button and it would advance to zero. Ball would have to be put back in the outhole and game would play 100% and then on the next game the 1000 reel worked correctly and each subsequent game. When the game did start at 7000 the game still worked correctly, so the game would work fine even though 1000 reel was not a zero. After many hours of efforts to correct this I have not found/fixed the problem, but as I say, after first game then the 1000 would always reset to zero. Now problem has become more "complicated". The outhole, 50 point, 300 point, ball return and 3rd chute relays ALL cause the game to move the 1000 reel five digits. Also, the score motor itself (by gently pushing it off the stop position) will add 6000 points, then next 1/3 rotation adds 4000 point, so every two 1/3 rev of the motor get the thousands reel back to zero. None of the relays are activated by just letting the motor turn. In normal game play all four of the reels work correctly, each will advance the next reel in going from 9 to 0.
Has anyone seen this issue before and found the problem. My game is very clean and as far as I can tell all the motor switches, relay and bank relay switches are set correctly, proper gaps, clean contacts, etc. Cannot figure how the score motor (with its 5 pointed cam) can cause 6 or 4 pulses to move the 1000s reel. I do have the schematic and a fellow pinsider has been helping but I thought some other input and experience might lead to the solution. I am stumped by this.
Thanks.
