Hi all, I purchased LED's and new Alltek lamp driver boards (main and aux) for my Kiss machine. I connected the control wires from each board to the tilt/game over/ wire on the lower right side of the back box door. Everything is functioning properly except the second "S" in the large KISS display at the top. In attract mode and self-test all lights illuminate except lamp 4 (per schematic) in the second "S". When I disconnect the control wire from the aux lamp driver board lamp 4 illuminates but is dimmer than all of the others. Additionally, during gameplay the second "S" never illuminates. Any thoughts or ideas on what could be causing this?
