The Aqua Logic system does operate my pump. I can turn on the pump manually by pressing the button on the bottom of the relay - so, the pump is wired and powered OK.
I've done some troubleshooting and here's what I've found:
1) Violet to grey resistance is 2.1-2.2 ohms
2) Blue to white resistance is 2. ohm
3) Yellow to yellow voltage is 22.4 VAC
4) Voltage between the orange wires is nothing
5) Voltage between red and black wires is NOT 18-33 VDC - I think it's almost nothing
Brand new board and local display.
Are the rectifiers bad? Can I check?
 
I've been reading another post and looked on youtube to try and solve my problem:

1) Violet to grey resistance is 2.2 ohms
2) Blue to white resistance is 2.0 ohm
3) Yellow to yellow voltage is 24 VAC
4) Voltage between the orange wires is .4 VDC - almost nothing
5) Voltage between red and black wires is NOT 18-33 VDC - I think it's almost nothing

Are the rectifiers bad? Can I check?
Any other options?
 

 
Also check the pink 4A or yellow 20A fuses I think are on your board.
