Unplug the alternator and see if it stops turning on at all. If so, ground pin 2 (W/R wire), and see if the bulb stays lit.

If so, it's an alternator problem.

 

First, the only alternator I'd put in is a Bosch (and I did). Yeah expensive. Not a fan of those "Chains".

Second, after 16 to 20 years old, I'd just replace this with the alternator or those with undiagnosed problems if the alternator is still good: http://www.ebay.com/itm/NISSAN-MAXIM...6cac3e&vxp=mtr

I hope this helps!

 

I have a 1999 model Nissan altima. I replaced the alternator now none of the controls on my doorare working, the alarmwill not activate and once I turn on head lights the battery drains dead after about 5 minutes. Replaced the alternator twice with the same problem each time.

 

I have a 6 gen Max and I have changed my battery and altonator amd car won't run longer than 20 min
