I have a outside Spa built by Palm Springs Corp it is about 7 years old, l am trying to find a circuit diagram of the mother board.

Motherboard was made by Spa Builders Systems [in the US] Model LX-25.
It has 2 pumps,ozone generator and 3KW heater.
This is the one in the bottom of the spa with the motors NOT the top control unit.

I have a basic block diagram of the board but it does not show the jumpers and what they do.

A proper circuit would be greatly appeciated.
