I believe it is an opto switch in the ball trough.

Start by putting the game in switch test and break the "beam" by poking something between the two IRs.... The trough jam switch is triggered when the trough supplies a ball to the shooter lane so you can see if it being triggered by poking your finger or a screwdriver down there.

It's a start.....
