Has anyone figured out the logic of the micro-switches that activate the various functions on a POD XTL? Mine has some switches that are intermittent, and few have stopped working all together.
I'm tracing out the lines of the Bank down / A / B / C / D PCB and I have continuity from each micro-switch back to the pin header, but when I activate a known working micro-switch, I don't see a change of state from OPEN to SHORT (When I press the micro switch actuator, I would expect to see it go from either OPEN to SHORT or the other way around)
Many years as a board level repair tech, am familiar with test equipment and such. Kind of stumped by this seemingly simple board.
