Good job! Now we can be (mostly) sure that your pot is not working correctly. Once you remove it, just double check the resistance (from the center lug to one of the side lugs) as you turn it. Technically, there still is a very small possibility that there is a short on the center lug from some other 5 volt point, but practically we have enough information to warrant you removing the pot from the board. Once you do this final test on the removed pot and find out that it’s bad, email us at info “at” zeppelindesignlabs “dot” com and give us your address and serial number so we can send you a new part.
