I'm finally back to working on my Silver Slugger project (Gottlieb System 3) and I'm stuck. Game powers on and starts a game and everything appears to play fine but after several minutes of being powered on, a few resistors on the resistor board below the pf start smokin'.
I picked up the manual and it looks like the pop bumpers run through the six resistors on this particular board but none of them appear to be locked on or anything. In fact, two of them work fine in test mode and one is non-responsive. I assume that one is the culprit but I'm not sure where to go from here. Can anyone give me some guidance? I have a few images of the board and segments from the manual that might help.
