Hello, I have a “Popper King” pachislo from the late 90’s? It’s made by IGT and it has bass fishing theme. My issue is this. Above the stop buttons there are three lights that should flash while the reels are spinning and go solid when the button is pressed. Currently two lights stay lit all the time and one never lights at all. I have tested the bulbs and they are all good. I suspect there is a flasher relay somewhere? Anyone have an idea where or what those relays would look like? I should add that the machine works fine. The reels stop as they should when the button is pressed. Thanks.
