MMU2s is constantly in power supply warning

I think it is most likely to be caused by a broken wire somewhere but I cannot seem to figure out which one.

For most part, it would run idler, move selector and then start flashing red and green. At first, all I had to do was unplug and re-plug in the wires, and it ran smoothly but now, it will not go past that point. I thought it was just pulley motor but I'm not sure as it did give me power supply warnings at other times like prior to starting idler, middle of selector movement, after loading filament into print head, etc on random one off occasions.

Does anyone know of a good way to check which of the wire is broken? Also, is there a way to just replace the wire? I want to make sure I order correct replacement part.

I forgot that I left this question on the forum. The issue has been fixed since. I re-flashed the MMU unit and it decided it was okay from that point on.
