Quoted from MagicMako:Well I made a quick video of my problem, I filmed the switch diagram in the "switch edges" test, you can see my hand in the reflection of the speaker panel, i roll a ball through the beam and it opens the switch but it does not close, I then give the playfield a pound and the switch closes again.
The switch changing state when you pound the playfield indicates a connection issue. My first guess, as I mentioned above, would be a cracked lead on one of the optos. The one on the right takes a lot of abuse due to launched balls. Could also just be a bad solder joint on one of the opto boards. Replace both of your long range optos. While you have them old one out, inspect the wiring closely and test for continuity on the wires. If okay, solder in the new optos and retest. Do not use Radio Shack optos. Get the correct WMS optos. You can get the optos individually for Rob Anthony (lockwhenlit.com), or buy the optos already attached to the small opto boards from the usual suppliers. Part numbers are listed in the manual.
Quoted from MagicMako:Also, I ran a few magnet tests again, and i was getting lamp interference errors again during opto check 1, which i had gotten before, then it went away for awhile, now it's back again.
When you replace the optos, make sure the new receiver goes on the same side as the old receiver. Same with the emmiter. I believe the emitter is on the right side (my game is on location 15 miles away or I'd look). Then run magnet test again.
