That cable should not have signs of heating, the amount of current is very low....but it looks like you must have a bad connection that is causing a high resistance and heating.... you need to get a new cable end and crimp it on....
You can dig around and find a competed cable on amazon, but it is handy to be able to extend or replace cables at times... these are links for the proper connector and crimp tool... the outermost jaw is for the jst-xh...the inner jaws will do dupont connectors which are also commonly used.

Pretty cheap right? Think it would work?
When I was asking about this for the ender 3 /u/robbob2112b gave a very detailed breakdown on what they had done.
> These are what I use on the tevo and when I put the e3dv6 on the ender I'll use them there too....
>I started them about 6 inches back up the wires from the hot end spaced them out so them aren't one big blob.... used different ones for different things so they can't be switched out and if for some reason a wire pulls loose it doesnt short anything... doing it I can swap out the hot end in minutes, do a PID tune and I'm off to the races.

>Any chance you could be more specific on the dupont connectors required?
You'll need 4 pin dupont housings and dupont female connectors and a crimper for them. That's assuming you have something to strip the wires as well. You can find the dupont female pins and housings cheaper places like aliexpress, ebay, etc.. but I recommend buying a quality crimper instead of whatever is the cheapest you can find as a quality tool will make the job a lot easier. If you're really strapped for cash, there's video's of people crimping dupont connectors with pliers online instead of the crimp tool.
>So <motor><cA> => <cB><cable><cC> => <cD><RAMPS board>
The wires transfer over to the same place from melzi to ramps, and pretty much any board. You'll have a X endstop, y endstop, z endstop, then connectors for the X motor Y motor Z motor and extruder motor, and so on and so forth. A ramps guide will help you visualize what to connect where.
>Any idea how big a cable for the power?
IIRC, the stock wires at 18ga, which is fine for the ramps board since it only draws 5A for all the motors, hotend, etc. The only other larger gauge connectors are for the heatbed, which I believe are also stock 18GA. FWIW, I'd go with a external mosfet instead of using the ramps on board ones which are rated for 11A, which is just within spec of what the bed draws.
I bought this crimper and it works great on JST:

AFTER I bought it, I found THIS one:

Which does JST and many more than the first. Grrrr.
