1976 Captain Fantastic. I've successfully rebuilt all flippers, drop targets, and pop bumpers and game was playing great. Ran into an issue where the game wouldn't reset from game over and adjusted the game over interlock relay. Game plays great again but none of the lights on the playfield light. Which switch in the game over interlock stack controls playfield lights? Thinking that has to be the culprit. Beyond that, where should I look? Thanks for any assist...you all have been a great help so far.
