I replaced the alternator and both batteries 3 months ago. 2 days ago my wife lost all power on her way to work. Had truck towed home. Popped the hood andfound red plastic cover on the lead and terminal cover melted. Have now charged both batteries but have not started and put a meter on them or the alternator yet.

What would cause the melting?
Would this be causing an issue with alternator?
Would this cause the batteries to not charge?

Any and all help is appreciated. Low on funds so need to do this myself.

Heat generation at a specific spot like that is almost always due to a high resistance connection. Clean it up really good and reattach it. You may even need to cut back and install a new terminal. Solder connections are best. Start the engine and watch your voltage at idle and at about 1500 rpm. Should be below 14.4 volts.
