K8400 struder n°1 problem

Good day
I have an inconvenience with my 3d vertex K8400 Printer
The senses that connect to the printer head, knocked to the head that heats the extruder, and I melted the wires.
The cables were melted purple, black, blue, yellow and Maron
Now I could connect all the cables from the printer, but the (Nozzle No. 1) to connect the printer begins to raise temperature me, without giving any instruction, (Nozzle No. 1) by itself begins to raise temperature

As I can solve my problem?

cables melted me, cut the part destroyed, and connect wires with electrical tape

but when I connect the printer temperature continues to rise

I checked the heater extruder is not the problem, changing the heater extruder No. 2 to No. 1, I see that the problem has to be something on the motherboard I have burned.

Please help me

If a electric wire melts, always by serious overheating or short circuit.
Also note: You posted this on the K8200 forum instead of the K8400 forum.

When building up the K8400 (or any 3D printer) : always triple check electric wiring before connecting the controller to the ac port.
