Confirmed power at box and inside unit. So doing my research I downloaded the fabulous Aquatrol diagnostics guide. Thank you internet for whoever created that guide!
Following through the steps I found that I did not have the correct 18-33 VDC between black and red wires so I replaced the rectifiers with part GLX-DRK. I now have 31 VDC between black and red on the main board.
Continuing to follow the guide, checked step H for PCB, reseated no apparent issues there. I do not have any voltage on pins 1 and 3 coming off the main board. It continues to say visually inspect for any damage but the board is in pristine condition. Am I just looking at replacing the PCB? Any other tips or things I should check? Including a Pic of the main board.
