YOU could have tried just touching the rods that go on the wrist to a .9999 silver wire somehow. SOTA is very expensive and I havent seen replacement parts from them that are affordable. A good seller on ebay is selling the ozonator for around 70$ now, much more affordable , plus sota never sent me a silver pulser unit i bought in 07 , they sent me some BS letter with some tracking number but it was never sent.
