Got a free dead Jandy VS Flopro from a frustrated fountain repair guy. Motor seems to spin. Broke apart the controller and it seems to be divided by the RS-485 comm board and the motor vsd board. There are 4 wires between them. Anybody know what signals are on the 4 wires? There are also 4 wires going to the motor.
