Yes, when I say AC i mean Air conditioning unit. The symptom begins when I use the Air conditioning unit and persists even after I disconnect it. Its almost like energy is being stored somewhere or the Salon Board is going into a certain mode. I can "reset" it by disconnecting and reconnecting the DC control jumper. I also notice the relay shut off even when I plug in the DC jumper cord. Or anytime I plug an extension cord in.
I am powering the Salon Relay Board VCC using 12v DC via a stepdown which pulls from 24VDC (I have the 12v coil model). The flashing relay #4 is controlled by Pin D34
D34. The contact side of the relays use 24V DC+ (NO) and flows OUT of the main panel through the 12mm connector/cable and into the SSR at sub panel. The DC- returns back to the main panel. The wiring diagrams suggest a 3 way switch Auto/Manual but these are currently taken out of the build for diagnoses. Check out the picture below to show you what I am working with. This is the sub panel, but please note Ive eliminated the excess ground wires.

Again, the switch stuff has been eliminated until I can figure out this issue.
Perhaps you can reiterate the conditions since I have eliminated the switches?
How do I test this?
To date, I have tried both. I ensured they were both sourced by the same 120VAC circuit which has correct wiring. 120V across hot and ground and 120V across neutral and hot. I see milliamps across neutral and ground.
I'm looking deeper into this. I did test my shed (which controls the Air conditioner) and neutral and hot were wired wrong by previous owner. I also came across an extension cord that has been used during testing which was also reverse wired. I fixed the extension cord and am no longer using the shed circuit until I have time to fix it.
I see the same issue using a different AC unit (similar BTU). I dont think it is the IN RUSH from the AC. I'm leaning towards faulty wiring in my house or some other issue with my panel wiring.
This is correct. Can we rule out the house wiring being that I ran the main and sub panel on the same circuit which is testing 120V across hot and ground and 120V across neutral and hot? I cant say for certain if another circuit is causing problems. This is quite the chore but its on the list to do. Thoughts?
