Looking for some info if anyone has had this same issue. I get optos registering when they shouldn't. In switch test if I slam both flippers repeatedly I get intermittent triggering of all 10 optos at the same time. Just a flicker. If I slam/hit/nudge/shake the game it doesn't do it. Only with both flippers.
Certainly seems like a power issue since they all trigger exactly together.
What I've done:
- Line voltage is good (through a voltage regulator to make sure). Game never resets anyway.
- Checked power(12v) continuity from PDB to 10-opto board and it's good. Voltage at opto board is same as TP1 on PDB.
- The unregulated 12v was a bit low(around 11v) so I replaced BR5 and C30 and now it's up around 14.3v and doesn't dip.
- I've installed a separate power supply for the accessories (lit buttons, ColorDMD, extra LEDs) just to make sure I wasn't straining the 12v.
- In the special system test/check it tells me all these switches(optos) are bouncy.
Other than re-pinning all the opto board connectors does anyone have any suggestion? I don't have housings or pins. Game plays anyway just annoying that I can hear it register switches when they aren't getting hit. Especially annoying to see the DMD animation for the ramp entry all the time.
Cheers
