The crypt popper on my BSD fires at random. Sometimes several times in a row, then nothing at all for a while. I've tested the solenoid, cleaned and tested the optos and both check out fine. The popper works fine when it's supposed to in gameplay but still fires randomly as well.
There don't appear to be any wires shorting either.
Im sure its something simple but i can't seem to pin it down so wondered if you folks had any ideas what might be causing it ?
