Check out my thread from last year on the same topic http://www.bonnevilleclub.com/forum/...ic.php?t=46623
. There'* a link to an eBay seller "member-200607", or DynaTech Corp, that sold me a remanufactured Teves unit. I wouldn't say their customer service responsiveness is top shelf, but the unit itself has operated flawlessly since installation. You might try contacting them to see if they have another rebuilt unit available (they should have rebuilt my old unit by now. . . ).
That'* after you make sure yours is getting power. Your symptoms sound identical, though.
