wpc flipper electronics rebuild(fixed)

[studley67]

please help.i have aquired a dr who with the flipper optos compleatly missing.
I am re-installing the components so it is back to how it should be.I have used new homepin opto boards a new flipptronics board but i still cant get the flippers to work in game mode.does the cpu determine if the switches are activated?or does the fliptronics board do this?
the flippers work in the diagnostics test.but not in game play.the switches ( optos) do not register in the switch edge diagnostics.

. $#$fixed. in typing this i realised where to look next.homepins new opto board has a test point for the 12vdc.so i tested.no 12vdc.checked the wiring.the grey/yellow was linking the 2 opto boards together but missing the active wire.i found the grey/yellow on the door interface board and re-routed it to the left opto board and voila we have flippers.i have earned my beer today.lol

Well done - I knew those test points would be handy someday.....
