Question about 2003 Nissan Altima
Changed Altenator, but no power going from altenator to battery,
See whit a multimeter if the current comes from the batery to the car.
After that check the cables from the alternator to the batery if they are broken.
Are the conections really tight?

Buy a fusable link at napa. The formula for creating one yourself is pretty confusing.

Don' t be so quick to think that it is the bearings. If the noise gets louder with acceleration try the alternator tensioner first. Mine was doing the same thing. Whining noise at start up and louder upon acceleration. Replaced alternator tensioner and the noise is gone. Hope this helps

sir , the altenator has 3 wires at the connector correct ? a white/red , a green/white and a black , the white/red wire is involved with a 10 amp fuse to do with the charging meter / gauge , the fuse located behind left side of dash .. the green/white wire is is involved with 2 fuses , a 10 amp ECU fuse and a 25 amp Main fuse located at left rear of engine compartment main box , and the black wire is involved with a main 80 amp fuse at the main box also . both of these 2 wires end up at the positive side of the battery , please verify all these fuses are good . if they are indeed good , then open wiring would be next step verify continuity on black and the white/green wires . i would post a link to diagram but autozone repair info site is down at this time . if ya need more help , please ask .

When the lights are on check the battery voltage. Should be 13.0 to 14.5. If you unplug the connector on the alternator when the lights are on, do they go off?

It is the two or three wire connector on the top side of the alternator. Either a wire has broke before the plug or there is a problem with the plugs terminals. The dealer sells a repair pig-tail if you need it.
