Quoted from explosiveegg:It's really annoying how behind Stern is with their OS.
On my RFM, the switch is test displays a picture of the playfield and shows you exactly which switches are active. I'm pretty JJP does this too.
I believe the Stern switch test will cycle through the active switches. If there is one that is interment, it should be appearing and disappearing from the list.
From what I've seen, this is usually an opto that isn't screwed in very well that the shaking of the game from things like pop numbers cause it to go in and out.
Thanks ill check the optos. The two thinfs that make that sound are trough rollover and left ramp. So maybe left ramp opto is loose.
Side note i like JJPs menus for switches
