Thanks Homepin but machine is 1968 which is pre manual and there is nothing in the back box. I have a schematic and know W relay (3rd chute relay) has a sticker over it with 3 plays relay on it.The P relay (2 plays relay) has a sticker over it with 6 plays relay on it . It also has a 2 coins relay (Q) . Really looking for some guidance with this guys
