Quoted from Cmjb13:To summarize...
I was working on the machine the other day and I had to lift the playfield. GI lights started having issues after that.
Resoldering the pins on the existing relay board as well as swapping it out with the one in the light box produces the same behavior: dim lights.
So yes, slight progress.
Last I looked, the playfield relay connector looked fine. I’ll try wiggling it when the machine is on to see if the light changes in any way.
Mmmm, go back to those “clean as a whistle” yellow wired connector on the right of the interconnect board and double check them, remove the connector. That connector is double looped, and often times the double part of the loop falls out or gets crappy.
