Car dieing

[leafybug]

My 1990 240sx keeps dieing when im stopped and have my heater and lights on, i replaced the battery and that helped for about 3 hours, but its dieing again, is it the alternator or something else? Also the deck keeps turning off when i turn the heater on, and when i put the lights on.

Check your battery terminals for tightness and cleanness, alternator belt and 75amp fuse. Sounds like alternator.
