Any time you have heat, you have a bad connection or too thin wire. I just fixed one for someone that burned up two adapters. The usual fix is to polish (clean) the connectors until they shine. Then bend in the female ones so there is heavy tension. I bead blast them when possible, except for the main power cord because I cannot get it all the way to the bead blaster.
Then reassemble them and turn in on again. Start feeling the outside of all connections and the cable itself. If there is no heat then wait for 10 minutes under load and check a second time. Any place there is heat felt, you have a poor connection. I did find one power cable once that the heat was coming from the cable itself. I cut back the cable about 2 feet and reinstalled the plug. Dissecting the cutoff piece showed that corrosion had crept down the wires itself for a foot or so.
On the female ends tarnx, or soaking in slightly watered down Catsup will usually clean them up. I have also heard, but never tried, soaking them in Coca cola.
Anyplace there is heat you have a problem.
