Have you gone into diagnostics and tested the switches including the optos? Many boiler room problems stem from a faulty opto. Common for Sys3 to have opto joints go cold or for the power resistor on the opto interface board to desolder itself.

Quoted from robotronjohn:FYI according to Clay's system 3 guide we can substitute standard leaf switches... So if you want to get a game working while waiting on the actual part from PBR you can do so.
Quoting Clay's Guide " Luckily though, Smart Switches are downward compatible to regular switches. So if a Smart Switch fails, it can be replaced with a normal blade or micro-switch (without a diode, as all Gottlieb switch diodes are remotely mounted on an under-playfield mounted diode board)."
Nice idea in principle but in practice it is more complicated. For example, is it a standup or laydown switch? Front mount or back mount? Does it have a target? Is it soldered to the harness or does it use a connector? Do you have an appropriate regular switch to easily substitute?
If you're going to get rid of the smart switch in favor of a regular switch permanently, it's one thing. As a temporary substitute, unless I absolutely had to have that switch working in the game today, I wouldn't bother. Steve Young ships so fast it's not worth the hassle.
