Hi, my inside controller is an fafco rs4, looks just like the aqualink or jandy rs4 inside controller. It worked fine then all of a sudden all the lights were on (red). I shut off the power at the breaker box and turned it back on then it'll go from looking as if there's no power to all red again. It seems all the timers are still in the main unit because it still turns on and off. I've looked everywhere and can't find anything thing on it.

So it just uses conventional AquaLink hardware? This is likely either a failure of RS-485 communications or a failure of the All Button (indoor) controller.
Pull the controller off the wall and inspect the four wires running into the back, make sure they are all secure. Pull the cover off the outdoor panel and do the same thing; in the top left corner you will see one or two red terminal blocks which should look the same as the one on the back of the indoor controller. The outermost wires (1&4) are power, the innermost black and yellow wires (2&3) are data.
If these are secure, you could take the controller outside and directly wire it to the panel with a short length of cable. This would eliminate any indoor wiring concerns.
If that still doesn't work, the All Button itself is probably bad - especially if you're saying the rest of the system seems to function totally normally.

Thank you and I appreciate it. Can it also be the battery on the board outside? I'm going to get into it tomorrow.
The battery's job is to handle the RTC in the device, it should run completely normally without it. But if you'd like you can remove the battery for a few minutes and reset everything and see if that helps. I'm still leaning toward an RS-485 comm issue, though.
