I have a Firepower that I recently installed two new flipper kits, during the course of which I managed to mess up the lane advance via the right flipper button. Not sure what I could have done but the land advance no longer works. I guess I could have impacted a solder joint somewhere during the process as the coils were kind of dangling free a bit as I installed the new hardware…I’m new enough at pinball repair to not know where to start looking.
Any suggestions?
