Why Is My Positive Battery Cable Hot. If battery cables and connectors get hot enough to melt their insulating material you have a problem. Why would the positive battery terminals melt.
Having a hot negative battery cable is a sign that there is increased resistance in the battery cable. If you have a bad connection on either the positive or negative cables the one with the bad connection will get hot when trying to carry current while cranking the engine. Was returning home from a short in-town trip when I noticed that my idle wanted to dip at a stop.
The biggest reason a battery terminate or connection would get hot is the connection is lose.
Somewhere there is too much resistance in the cable. Sometimes the cable still looks good but inside the copper will have broken up to a point where. Report This by Manage My Life. Chemical reactions with copper clamps are not rare either.
