I have a 06 Sundance Cameo with 1 single stage circulation pump and, 2 single stage jet pumps. one of the jet pumps started running constantly and will not turn off whether I hit the pump on/off button on the topside controller. I am assuming it is a relay that needs to be replaced on the circuit board (P/N 6600-161) but I am unsure which one it would be (K4, K5, or K6) I guess I could replace them all but if I only have to replace one I would rather do that. does anyone know which Relay(s) I need to replace?
