There is no item in the console that could explain the symtoms you describe.
Cleaning electrical connections/grounds can help electrons travel where they should with less resistance (usually a Good Thing). Simply removing/replacing connectors can often (temporarily) helo them make better connections. But that won't make the battery boil.
Many chain auto supply store will test the starting/charging systems for free (keep in mind they tend to want to sell you things but if you are having a problem they should be able to point you in the right direction). If it were me, I'd remove the alternator & take it to Ye Olde Fashioned auto electrical rebuilding shop (typically an old place on the 'wrong' side of the tracks). They can test it and if needed repair it.
