NISSAN MAXIMA NOT STAYING RUNNING
 

I HAVE A 97 NISSAN MAXIMA AND I HAVE BEEN HAVING PROBLEMS WITH IT. I THOUGHT IT WAS THE BATTERY, SO I REPLACED IT. THEN IT WAS STILL NOT STAYING RUNNING, SO I FOUND OUT THE ALTERNATOR NEEDED TO BE REPLACED. I REPLACED THE ALTERNATOR AND IT STILLS SUCKS ALL MY JUICE OUT OF MY BATTERY BUT I TESTED THE ALTERNATOR AND IT IS GOOD. I HAVE NO IDEA WHAT THIS COULD BE. ANYONE ELSE HAVE ANY SUGGESTIONS?
