I shall have a look in a moDo all the trough opto's work? Forget about the first one nearest the flippers. There's one at the other end of the trough that's made when popping a ball up, maybe that one is out?
After searching pinside I think I may of solved the ring light and flasher prob. A 5 sw and diode assy #c-13940. It's been jumpered and looks a lil worse for wear

Jumper doesn't necessarily mean the board is fubar. Test all connections and components on it before replacing it.

Either reinstate the high power interlock, look for the disconnected cables in the base, or before you raise the playfield, whip the power connector off the trough opto board, so making machine think balls are still in place.
Sounds like your having a rough day, I'm sure you'll figure it out.one thing to bear in mind is the boot up diagnostic and test report often report switches that aren't faulty at all just because they haven't been operated ingame for a few games. The other day I started getting report check some of the switches on the battlefield just because I had played quite a few games without hitting a ball up there.
If someone else knows more about how this works I'd like to know, for instance does a certain number of games without activating a switch mean it gets reported?
It's the 3 red flashers that are alone the wireforms with the rings. Cheers andy I will try and have a look tonight
Presumably you mean flashers 21, 22 & 23 (see manual page 2-43)? - which are orange (usually).
Are the bulbs OK - swap with ones from the back wall (which I presume are working)?
Re the optos - you can check that he emitter is working with a camera phone. You will probably need to get the phone in the beam, but if working, you should see the emitter glowing blueish (check with a working on e.g. battle field as it's easy to get the phone in the beam).
You mention that you have checked continuity on the wires - but have you also checked for power - at both the opto PCB and again on the leads that feed the emitter and receiver ?
