Spliced the new sensor into the original 8" lead that came with the spa, We did do a continuity check with an ohm meter before using the old lead. The new sensor did not come with the appropriate lead. I will do an ohm's check and post the results. Thank you!

Good afternoon! We have a 2004 Sundance Bahia Spa, 240v/60amp 3-wire hot tub. I had a licensed electrician test the 240v components, pumps, heater. Two weeks ago the spa lost water temp (62°F) and showed an OH code with a temp of 109° F. We replaced the temp sensor and the display now flashes an overheat (OH) condition and reads 118°F. Both main pumps work on demand as does the circulation pump. We tested the flow switch by jumping the circuit at the pins on the control board and got a FL code. We jumped the lead at the CB pins for the high temp sensor on the heater and got the proper code when disconnected. The circuit board PN is 6600-288 REV A. Available CB's now cross to a 6600-726. Any suggestions would be extremely appreciated.
