I just finished my high-voltage section upgrade. However, now that the displays are dimmer, I have noticed an issue with the player 4 display, consisting of the 1st and sometimes 2nd digit flickering. I tried reseating the contacts per Vid in his thread, but that did not work. I swapped the connector from one display to another, and that made the same glitch appear on the other display, so that rules out an issue with 4th player the display itself. That leaves the wiring harness or the master controller itself, or so I can at least figure. I suppose I will have to pull the master and look it over. Anyone have a similar issue before, and what was the cause?
