Hello Glen - I did a double take logging back in - "K9SJH" was the "Featured" member, lol - close ! Okay, thanks for letting me pick your brain this way, I greatly appreciate the assistance. I did your last suggestion and found this: between pins 1 and 3, I had the correct resistance, and when rotating the unit, the ohmeter moved slowly. However, although I would also get the correct resistance between pins 3 and 7, the needle would not move during rotation - it just stayed the same. So, can I conclude the wiring is good (I do have a connector in the long line). Maybe, as you initially suggested, something is wrong with the rotator pot itself ?
