Every time the heat is turned on the engine fails. There is a burning rubber smell and rubbing/dull squeaking noise coming from the engine.

You sure the alternator is producing the correct output voltages during a heavy load

Absolutely sure that the alternator is not the problem. Charge on the battery is fine. Only have problems when turning on the heat/defrost etc.
