I have an Austin Powers that has me stumped. Scoop switch intermittent. Every switch in the column or row, before and after work fine in test or game play. All switches register as fast as you can click them.
I clamp a meter to the switch and it registers as fast as you can click it. In test it registers very slow. Or every other click or not at all.
I changed the micro switch and diode. Was working well for a while now back to the same thing.
