if found out that the wire wasnt good, so i replaced it. But the 4 hashbord heat the wire melt, so i found another hashboard and everything is fine. What is the second mode?

Where did you get a replacement wire? It will melt if you are using very thin wire or cables.
I'm a bit confused do you have stocks of hashboard as a replacement?

What exactly second mode are you talking about?

A mostly short circuit is the reason why wire and cables are melting without a multitester we do not know if the hashboard is shorted or not.
