Hi Guys, I'm stumped here. I have almost all issues fixed but 1. The pop bumpers. The lower pop is fine and works correct. The upper 2 pops is where my problem is. In switch test under the playfield if I manually test them I can get them to register. If I push the left wafer the left coil fires and so does the right. If I push the right wafer it fires and so does the left. If I push the lower wafer it will fire alone like it should. What am I missing? I checked wiring and it all looks right. I know its not a board problem as I have swapped it with another. Any Ideas? Diodes test fine.
