Are you aware that opto TX & RX diodes have polarity and must be inserted in the PCB (or wired) the correct way around or they won't work?

Quoted from ibjames:At the solder points on the board with the little black receivers on it
Are the black things the photos? I'm trying to get my terminology down
The small, round black plastic packages with (usually) two legs are "opto receivers". The one at the the other end of the (invisible) light beam is the "opto transmitter" and (usually) they are in a clear package but can be a light pink.
In most pinball applications, they both are wired to a control circuit that is usually close by and the signals are handled by that board and passed on to the main control board (the MPU).
Both are diodes and MUST be connected the correct way around - IE: they have polarity.
