ok, just hoping someone might have a pic of their control box wiring diagram. Thank you. I'll give that a try.

hi, the previous owner told me their son tried to fix it and I'm not confident they put everything back correctly so would like to have the wiring diagram to ensure all jumpers, dip switches and connections are correct

Hello, I recently bought a 2009 Marquis Epic spas (with circuit board: s/n 54278-04x, Marquise MQ2KU EL2 M3). I'm having trouble with my heater and need to troubleshoot my connections and dip switch settings but I'm missing the control system wiring diagram from the control box lid & so far I can't find this online anywhere. If anyone can share a picture or .pdf etc. of the system wiring diagram for a 2009 Balboa Marquis Epic spa it would help me out greatly. If everything is set correctly, I'll probably need a new heater, sensors, &/or a new circuit board, but want to take it one step at a time. I'll attach pics showing the circuit board info., chip, and current dip settings in case it helps. Thank you, -Kenneth
