Quoted from pinballdork:If I leave the machine in switch test mode, and don’t touch anything, It’ll randomly register both switches, also. I haven’t tried disconnecting the switches and leaving the power& IO to the board. I’m not home. But I do have one LED on the board that is lit. Funny, the optos did seem to occasionally trigger when I fiddle with the fuel shot area also. But not consistently. ???
I would replace the opto(s) that are registering. I have seen some weird behavior when they go. My Sparky started randomly triggering. In switch test I found that it would trigger any time I touched the left ramp with my finger. I figured it was shorting somewhere, so I checked everywhere and even went as far as insulating the entire wire with electrical tape, yet it still did it. Finally gave up and ordered a new one, and that fixed it right up. That was a weird one though.
Such a great game, and now that EOTL is obtainable by mortals it is really over the top.
