I just went out with my fluke and measured everything I have 120 volts at the terminals I undid the circulation pump put a temporary plug on the end of wires and plug it into an extension cord and I have nothing at the circulation pump so thank you and I'll look up a part number and possibly see if I can order one local or order one from a warehouse thanks and see if that's my problem. I have a Watkins Bengal model M serial number M1 G1 257
