Original poster: "by way of Terry Fritz <twftesla-at-qwest-dot-net>" <Beans45601-at-aol-dot-com> Is it possible for only one side of the nst to work? I have 2 15/30 NST's, and at first, one of them stopped to work on one side. Then, a day later, the other one did the same thing. but, on one side, everything is peachy! what is going on here... Thanks Adam
