Welcome to our forum.
Hello everyone, brand new here, but I have this exact same issue with my tub. I have a 2001 Sundance Altamar. Can someone explain how I can go about switching the wires to the second relay? My setup is identical to the one pictured. Thank you very much.
Clover, thanks for the information. I tested the circulation pump, and it does not turn on. I will check if there is power going to it later on today. If the pump itself were to go bad, could it cause the 30a fuse to blow? I heard that only the heater has enough power to do that,
