After searching the archives, I know this question has been asked a thousand times, but I am not grasping what to do next.
My IJ has suddenly started blowing F116 whenever you hit the flippers. I disconected J118, which stopped the fuse from blowing, but also disconnects the flippers. I ran a full battery of tests, and it appears to be ONLY the flippers which are not working.
So I'm not sure what to test next. I am getting a solid 12V from the TP on the board; I am confident BR5 which serves the 12V is working, because the other coils are firing. And the coils themselves are not causing the fuse to blow, it's the buttons themselves(?!)
So do I need to start looking at the Fliptronics board? I have never had to diagnose anything on that board. The fuses there look OK; I am about to pull them to test for sure.
