I do have the book and the schematic. However, I will be the first to admit that I am not very good at reading the bingo schematic. I can read the EM Pins schematic much better, probably because I am more used to them. In any case here is what I have found.
Turning machine on with balls in the playfield holes.
1. Press coin switch to simulate coin being deposited.
a. Multi-play relay activates only
b. lights are not on relative to the holes the balls are in. I need to activate the anti-cheat relay for the lights to come on.
2. If more coins are added, nothing happens.
3. Activating the Start relay manually
a. Table opens and balls drop
b. One ball is lifted into slot
c. Control and search motors start to run
4. Shooting first ball closes table
5. After 4th ball is shot, the control and search motors stop running. I realized that this only happens if there are no credits. If there are credits, the motors continue to run.
Only 1st card is activated.
When machine is turned on with balls underneath playfield, the control and search motors come on when the machine is powered on.
The coin switch seems to only turn on the multi-play relay and nothing else. So I assume that is why only the first card is in play.
The search unit motor always runs when the control motor is running.
I have cleaned the contacts on the control unit.
I have also cleaned the contacts in the 4 relay bank in the back cabinet Anti-Cheat, Multi-play, Start, and Replay Reset relays.
The coin lock relay is not activated so coins go through directly to the return tray. That is why I have been manually pushing the coin switch.
Even if I manually put credits on the game, the credit button will only activate the coin lock when pushed.
Let me know if there is any more details that would help fix this game.
