Is the inside switch (in the doorway on the side) to cutoff the battery on or off? Are the coach batteries charged and connected? Are you plugged into 120 or on batteries only?

Thanks for all the suggestions and your efforts to help.I called the prior owner (who was the second owner) last night and he said he had never used the system and just dumped like a conventional RV. He said he just manually pulled the black and grey tank valves. I'm a little embarrassed that after crawling under and investigating further, I found that both electrical valves have been deactivated and turned into manual valves (no electrical connections, no gears etc.). Yesterday I had inspected only the wiring behind the panel with the switches etc.. I won't bother trying to fix or replace those. I then ran 12V direct to the sani-con pump (macerator?) and it did not come on, I tried to move it with a screwdriver, etc. and nothing, so I assume it is dead. Not going to replace that either! I will make extension handles for the valves so i don't have to crawl under the rig to activate them, and will just dump the good old-fashioned way through a stinky-slinky.
The following is a photo and notes I have for our 2016 PC2552. It may help in troubleshooting your problem.The top mini breaker (50 amp) is for the battery feed. The second breaker (40 amp) is the charge breaker. The third (20 amp) with black wires is the macerator pump breaker. The fourth (20 amp) with the brown wires is the slide out breaker. The fifth (20 amp) with the green wire is to the electric mini sofas. The black cube relay controls the macerator pump. The 10 amp latching controller turn the water pump on and off from multiple location.
flei,I admit I never dug into the main wiring of my PC, only peripheral circuitry to make specific modifications to things like the battery shield, stove hood, and the blanket change to LED lighting. I shy away from core changes for fear of unforeseen issues. Features like the sanicon system, I'll repair before changing, but that is my thinking to this day. Maybe later, I will develop a different RV maintenance strategy.Funny, I never even seen in my PC, that bank of diodes or whatever they are. Maybe I have them, just never stumbled on them.
