Do this get a voltmeter read the battery before you start the Maz it should read above 12.4 volts and over - record reading. Now start it up and turn headlights On and heater to high. Your reading should be between 13.5-15.5 volts- If not the alternator is not putting out.
Also the battery might not be taking the charge, or the electrical system has a short creating an excessive current draw.
