You know I have that volume control and the resistance measurements were off by 100% from one side to the other. I have read the replies with help but it is 12 deg. here and too cold to work on fine stuff. I really don't mind troubleshooting, I believe you learn more that way than any other method. I love the names that click and clack give the help; Heywood Yabuzzoff Their cheuffeur is Russian; Peikup Andropov The butler; Mahatma koat.
