Hoping someone can point me in the right direction. My HS was all working ok .....then all three Pop bumpers stopped as well as the left and right kickers??. Look for loose connections and broken wire ...could not see any thing . If I run the switch diagnostic it does not pick up the bumpers or the kickers. If I use the diode and jumper lead..the display suggests that all is good . If i start the game and fire the connector with another switch on the same row...the coil doesn't fire...score increases..Maybe my brain is fried from all of the xmas stuff. Oh ..I also changed the TIP 122 tranny over as I had some in my kit. I would appreciate any suggestions.
