I bought two potentiomeers recently, they are both 10K rotary made by the same company. Initially the only difference appeared that relative to the board one has the rotary dial flat, the other upright. The first worked as expected with pin1 - signal in, pin 2 - signal out, pin 3 - ground. The second doesn't work at all with pin 3 connected to ground.
I'm presuming the pins were switched so pin 2 is ground now? Is there supposed to be a standard configuration?
It does seem to work with pin 3 disconnected and no ground at all, will just leaving it like that make any difference?
Thanks.
