I have a hot tub issue: Sundance Cameo 8/21/2006 CA3850-100247721-0806 P/N 653-099REV.E The issue: The circulation pump went and I called a local hot tub repair place. The repairman verified the pump was bad and installed a new circ pump. It began giving an error code with an SN1 and ILOC after he had given up and left. However, he left without reconnecting the plugs form the J6 harness. He had also broken one tab (on the jumper wire) and crushed some others. I opened these with a paper clip, replaced the jumper wire and re-powered. I also checked the 4 small fuses and one was blown, so I replaced it. Still the same error codes. I also replaced the temp sensor and flow sensor because they were about due anyway. Same error codes. I temporarily wired the circ pump and disconnected the two main pumps so it will at least circulate (which works fine). I suspect that he damaged the J6 harness somehow. What else should I try before purchasing another J6 harness and trying that?
