New board on Aquarite does not work with no light or display.

The rectifiers were "upgraded" to better ones by B&L Enterprises a few months ago. I was told that thermistors go bad because of overheating from rectifiers.
Would the fuse die with this cable issue even if the board is not turned on? OK. The rectifiers might be bad...
 
The original bridge rectifier is spec'd at 35A @ 400V. The rectifiers can be replaced with Bridge Rectifier Single Phase Standard 600 V QC Terminal GBPC from Digikey or Mouser - Mouser #: 583-MP356 Mfr. #: MP356 Mfr.: Rectron Description: Bridge Rectifiers 35A 600V.

Inyopools has a Rectifier Upgrade Kit - GLX-DRK (Aqua Rite)

You can use the existing Red & Black wires or you can build your own if needed. Your local auto supply carries the spade connectors and 14 AWG wires. Cut to length and crimp. It is very important to follow the label or pin-out on the replacement bridge rectifier when connecting the wires. If in doubt, ask![44]

The orientation of the rectifier and the correct wire connections is important. One corner should be cut to indicate the orientation. Also, three terminals are vertical and one is horizontal, which can also indicate the orientation.

You just need basic bridge rectifiers.

I think that something like the following should work.

Maybe someone else can confirm?

The old gen Goldline AQR swcg use 20A glass fuse mounted at the bottom of the metal enclosure. The Red & Blk wires carries the electrical current from the bridge rects to the mainboard.
If you are not sure which one of the two rects went bad, then yeah go ahead and shotgun them. As JamesW mentioned earlier, there is nothing special about the bridge rectifier.

Thank you so much for the helpful comments. Working fine, so far. Are the rectifiers getting too much heat from the chassis? Any way to isolate them? The bad rectifiers were KBPC5010.
