I've got an odd switch issue going on with my DH. When you trigger the right ramp enter (switch #51), switch 31 (left ramp enter) and switch 41 (Trough opto) are registering with it. 31 and 41 are both optos and test independently. Switch 51 is a micro switch, is wired correctly and has a good diode attached to it. I took the CPU out and tested it in Flintstones and switch 31, 41, and 51 tested as they should. I took the 16 opto PCB under the playfield and tested it in Scared Stiff - Again no switch issues found. Not sure where to go from here. I didn't test the cpu from flintstones or the opto PCB from scared stiff in DH because they are not in the same location. Any thoughts??
